7 Gray RMC ready mix concrete suppliers near me, Packaging Type: truck, Grade Standard: 5

Ready mix concrete refers to concrete that is specifically manufactured in factory and then delivered to the construction site in a freshly mixed or unhardened state instead of being mixed on the site. It is usually transported in cylindrical trucks known as cement or transit mixers. Ready-mix concrete varies by its 28 days compressive strength which is designated as M15, M20, M25, M30 etc. M15 implies that the compressive strength of concrete will be 15N/mm2 after 28 days. The grade of concrete is defined by the structural engineer designing the building. Ready Mix Concrete is bought and sold by volume – usually expressed in cubic meters.Advantages of RMC: RMC has perfect proportions of cement, coarse aggregate, sand and water which ensure uniformity and high strength of concrete. It increases the speed of construction and reduces the labour requirements. There is no need for space for storing the materials like coarse and fine aggregate, cement, and admixtures if you are using RMC. Moreover, RMC helps in reduction in noise and air pollution.Limitations of RMC: There are chances of setting of concrete if transportation time involved to deliver RMC is more. Generally, admixture and retarders are added to the mix which prevent its setting.RMC without Fly Ash: Usually prepared by using OPC Cement while preparing a concrete batch. RMC without Fly Ash is more expensive than the one with fly ash. Also, RMC without fly ash is also accociated with lower setting time and early attinment of strength.
