With the use of 100 percent manufactured sand, the strength of concrete can increase by up to 7.5 percent. Due to less surface area and better grading of m sand improve the workability of concrete. The flexural strength of the concrete also can be increased by using m sand. Because manufactured sand is processed from a selected grade of …
Ready-mix concrete, or RMC as it is popularly called, refers to concrete that is specifically manufactured for delivery to the customer's construction site in a freshly mixed and plastic or unhardened state. Concrete itself is a mixture of Portland cement, water and aggregates comprising sand and gravel or crushed stone. Uses 1.
