What is ready mixed concrete
Ready mixed concrete means to concrete that is blended to be delivered from a central plant instead of being mixed on the job site. Each batch of ready mixed concrete is specially manufactured to the contractor's specifications and delivered to the contractor in cylindrical trucks, commonly known as "cement mixers", in a plastic state. Ready mixed concrete for delivery from a central plant instead of mixing at the construction site provides an option that is easier for the customer to use and transport. When the ready mixed concrete reaches the construction site, it is frequently remixed to ensure that the appropriate precipitation is obtained. However, the remixed concrete tends to be set up faster than the concrete which has been mixed only once. Materials such as water and some additives are often added to the workplace at the workplace after blending to ensure that the specified properties are obtained before placement.
Contrary to popular belief, ready mixed concrete and cement are not the same thing. Cement is actually just a component of ready mixed concrete. Ready mixed concrete is made up of three basic components. Which are basically water, aggregate (rock, sand, or gravel) and finally cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates. This combination, or ready mixed concrete, will be poured and harden into the durable material which we are all familiar
Quality concrete is obtained as a ready-mix concrete mix plant make use of sophisticated equipment and consistent methods. There is strict control over the testing of materials, "process parameters" and continuous monitoring of key practices during the manufacture.Poor control on the input materials, batching and mixing methods in the case of site mix concrete is solved in a ready-mix concrete method.
TYPES OF READY MIXED CONCRETE
Ready mixed concrete may be examined under three categories due to the mixing ways of it. There are three types of ready mix concrete (RMC) depending upon the mixing of the various ingredients as given below:
- Transit mixed concrete
- Shrink mixed concrete
- Central mixed concrete
