RMC (Ready Mixed Concrete) is concrete that is specifically manufactured in a ready-mix plant according to a set recipe or as per specifications of the customer, at a centrally located batching plant.
It is then delivered to the customer’s construction site in an unmixed state in the transit mixture of the truck.
Unlike ordinary concrete, RMC enables precise proportioning and uniformity of the concrete components. This ensures that the strength, workability, and quality of concrete remain consistent throughout the batch.
RMC also contains various admixtures, such as fibers, admixtures, pigments, and admixtures. These admixtures make the RMC much more durable and easier to use. It also reduces shrinkage from drying and cracking.
RMC also has a continuous quality check, which helps maintain the quality of the concrete. In the ordinary concrete, that quality check is not done, which can lead to the inconsistency in the quality of the concrete.
The less water used in RMC also makes it an extremely resistant form of concrete, making it more durable than traditional concrete. This also gives it greater power to resist external forces such as vibration, heat, and pressure.
Last but not least, RMC reduces the amount of time needed to complete the construction works, since there is no need to manually handle the concrete during production or transportation. It also saves costs in terms of manpower, equipment, and materials due to decreased labor, fuel and other resources.
What are the advantages of using ready mix concrete instead of site mixed concrete?
Using ready mix concrete instead of site mixed concrete has a number of advantages including convenience and cost savings. Ready mix concrete is premade and delivered to the job site, saving you both the time and energy of sourcing, delivering, and mixing the materials on-site.
Additionally, ready mix concrete is made under controlled conditions in a batching plant, meaning that each batch can be held to a higher level of quality control than would likely be possible with site mixing.
Ready mix concrete production often includes automation and improved efficiency, which can also help to lower costs. With ready mix concrete, you can also choose from a variety of concrete mixes and additives to customize your project for the specific application rather than relying on a site operator to mix a specific mix on-site.
Ready mix concrete also means less labor costs and a more consistent product overall. In summary, using ready mix concrete can save time, energy, and money while delivering a higher quality, more consistent product.
What is the difference between ready mix concrete and cement?
Ready mix concrete and cement are very similar in that they are both used for making concrete, but there is a big difference between them. Ready mix concrete is a pre-blended mixture of cement, water, and aggregate (like sand and gravel) that is delivered directly to the job site in a ready-to-use state.
Cement, on the other hand, is an ingredient used to make concrete. It is a finely ground, grayish-brown powder that is the main binding agent in concrete, and when mixed with water, gravel, and sand becomes concrete.
Cement does not have the aggregate mixed into it and does not contain anywhere near the same amount of water that ready mix concrete contains. Cement also requires a certain amount of skill and knowledge to properly mix, whereas ready mix concrete can be poured with no additional mixing.
What is the strongest concrete mix?
The strongest concrete mix is a mix composed of cement, aggregate, water, and any optional ingredients that are added to create a desired effect. Cement is typically composed of a mixture of calcium, silica, alumina, and iron oxide and has a higher compressive strength than other materials.
Aggregates are classified based on the size and other properties of the particles; for example, smaller particles may be used for increased strength and larger particles for greater workability. The water in the mix plays a vital role in the hydration of the cement and helps the mix to reach its desired strength.
Additionally, the ratio of cement to water affects the concrete’s strength, thus other optional ingredients such as superplasticizers may be added to reduce the amount of water needed and increase the strength of the concrete.
Ultimately, the strongest concrete mix will depend on the ratio of ingredients and the desired strength, workability, and other qualities needed for the project.
Which is better cement or concrete?
The answer to this question really depends on the application. Cement is a powdery substance made from limestone, clay, gypsum, and other ingredients. It is used as a binding agent and when mixed with water, it forms a paste.
This paste is left to harden and form a solid structure that is strong, durable, and resistant to environmental conditions. Concrete is generally a mixture of cement, sand, gravel, and water. It is generally used in applications where a strong and durable material is needed, such as in foundations or roadways.
In terms of which is better, cement or concrete, it depends on the application. For example, for smaller projects where a strong bond is needed, such as an adhesive for tiles, cement is usually used.
For larger and more permanent structures, such as foundations or buildings, concrete is usually the better choice since it is much more durable and resistant to environmental conditions.
What is ready mix concrete used for?
Ready mix concrete (also known as RMC or pre-mixed concrete) is a homogeneous mixture of cement, aggregates and additives, which is prepared at a batching plant and transported to the point of construction in special trucks equipped with revolving drums.
Ready mix concrete is used in a wide variety of construction applications, whose uses can vary from freeing, fencing posts, simple structures like footings and foundations, up to complex structures such as multi-storey buildings, bridges, and factories.
It is especially preferable for large scale projects, since it allows for a higher speed of construction and easy on-site mixing. Ready mix concrete is typically used wherever uniformity of the concrete mix is desired and when large amounts of concrete are needed.
Applications range from basic slabs, walls, and foundations to more specific uses such as marine construction and maintenance, detailed landscaping, noise barriers, and projects requiring special attention to durability.
Ready mix concrete is especially beneficial in certain areas such as high rises, bridging, roads, tunnels, and other large-scale projects which need highly specialized materials. It is preferred in multiple-unit dwellings and other larger-scale projects due to its low cost and time-efficiency, allowing for both the initial installation and positioning of the concrete to be done in only a few hours.
Is ready mix concrete good for construction?
Yes, ready mix concrete is a great option for construction. Ready mix concrete is a pre-mixed material produced in a batch plant and then delivered to a construction site via truck-mounted mixers. It offers many advantages to construction projects as compared to traditional sites-mixed concrete.
First, it saves time since it is pre-mixed and therefore, it is quickly ready for use on the job site. Secondly, it reduces labour costs since it requires fewer operators than site-mixed concrete. Third, it provides superior consistency and accuracy of the final product since the constituents used in the ready mix batch have already been correctly proportioned.
Another advantage is its enhanced strength, durability, and better surface quality. Ready mix concrete eliminates the need to store and mix large quantities of material onsite, which would otherwise increase the cost, complexity, and duration of the project.
All in all, ready mix concrete is an excellent option for construction projects.
Is ready mix concrete cheaper than mixing your own?
It depends. Ready mix concrete can be convenient, as it is already mixed and ready to be poured. However, you must factor in delivery costs. If there is a short lead time and need to get the job done quickly, ready mix concrete is probably cheaper.
However, if you can plan ahead and don’t mind spending a bit of extra time, mixing your own concrete might be the better choice. Ready mix concrete usually requires the use of a concrete mixer, which can be expensive to rent, so unless you are planning to use it for multiple projects in the future, mixing concrete yourself might be more cost-effective.
Additionally, you have more control over your own mix design when mixing concrete yourself, which could make it a better option for more complex projects.
Is RMC better?
Whether or not RMC is better is ultimately subjective, depending on what your specific needs and preferences are. RMC stands for Ready Mixed Concrete, which is composed of cement, water, and combination of sand, gravel, and other admixtures.
It is created in a factory, batching together the different components in the right proportion, and then is delivered to a job site. This concrete is pre-mixed and ready to use in a variety of applications, making it an easy choice for DIYers and professionals.
In comparison to traditional concrete that is mixed on the job site, RMC offers several advantages. It is highly consistent and eliminates the risk of mis-estimating how much materials are needed for a project, reducing the possibility of overages or shortages.
It also reduces labor costs as the mixing can be done by the supplier and it requires less skill to operate the machinery used for mixing. Additionally, since it does not require any wet cement to be moved, it is a much safer option for workers on the job site.
Ultimately, whether or not RMC is your best choice will depend on your individual needs, goals, and preferences. It is up to you to decide which option will best suit your particular situation.
How strong is bagged concrete?
Bagged concrete is a pre-mixed form of concrete and is commonly used for smaller construction and home improvement projects. Many types of bagged concrete are available, and their strength depends on which type is used.
Typically, these types range from a low strength of 1,500 psi and generally reach strengths of 5,000 psi and above. Some specialty types of bagged concrete, such as ultra-high performance concrete, can even reach strengths of up to 20,000 psi or more.
Generally speaking, many smaller, common home improvement projects are done using bagged concrete that has a strength of around 2,500 to 3,000 psi. Meanwhile, large scale commercial projects typically use a higher strength bagged concrete, such as a strength of 5,000 psi or more.
In addition, regardless of the type, the concrete’s ultimate strength is strongly related to the conditions in which it is used. For example, proper curing and reinforcement are essential in order to achieve maximum performance from the concrete.
How long does ready mixed concrete last?
Ready mixed concrete typically lasts for many years and can last indefinitely when appropriately cared for. The longevity of ready mixed concrete depends on the environment that it is being used in, how it was prepared, the quality of the concrete mix, how thick it is, and how much reinforcement (if any) is present.
In general, ready mixed concrete can last up to 25-40 years if it is used in a dry and normal environment, prepared properly, and contains good quality concrete mix. However, if the environment is wet or has extreme temperatures, the life of ready mixed concrete may be shorter.
Additionally, if the concrete mix has been contaminated with dirt or other impurities or is too thin, the longevity of the concrete may be considerably lower. Furthermore, when reinforcement is present, it can help to increase the durability and strength of the ready mixed concrete, and thus can extend its life span.
What concrete mix is the strongest?
The strongest concrete mix would depend on the specific requirements of the project. Generally, a mix of one part cement, two parts sand, and three parts gravel (known as a 1-2-3 mix) would be considered a good all-purpose concrete mix, and is the most commonly used mix for most applications.
Other mixes might include a 1-1-2 mix, which adds additional strength, or a 1-3-5 mix, which is typically used for large foundation projects. It is important to consider the purpose of the project when selecting the appropriate mix, as some mixes are optimized for higher compression strengths, while others are better for withstanding extreme temperatures or weather conditions.
Ultimately, working with an experienced concrete professional or engineer is the best way to determine the right mix for a given project.
Can you concrete over old concrete?
Yes, you can concrete over old concrete. However, it is important to take proper preparation to ensure the new concrete adheres to the existing material. First, you should inspect the old concrete to make sure it is structurally sound and any loose material is removed.
The old concrete should also be cleaned and dampened prior to pouring the new concrete. The concrete should be tamped down with a vibrating plate compactor to ensure a stronger bond between the two layers.
If possible, use a curing agent to finish the surface of the concrete and reduce the chance of further damage to the structure. It is important to maintain a regular supply of water to the fresh concrete and protect it from the elements for at least 48 hours to ensure proper curing.
Overall, concrete can be applied over old concrete but careful preparation and protection is necessary to ensure its durability and longevity.
