What is concrete?| Manufacturing process of concrete
Concrete is a mixture which is composed of materials like cement, fine aggregates (sand) and coarse aggregates mixed with water which hardens with time. Concrete is the main material for 90% of construction works. There are many types of concrete based on the the materials used in the mixture during manufacturing process of concrete.Concrete: Manufacturing Process . A good quality concrete is essentially a homogeneous mixture of cement, coarse and fine aggregates and water which consolidates into a hard mass due to chemical action between the cement and water. Each of the four constituents has a specific function. The coarser aggregate acts as a filler.Concrete: Manufacturing Process BrainKart

How Cement is Made Cement Ingredients History of Cement
This Portland cement is a fundamental component of concrete.Concrete is produced when portland cement makes a paste with water that joint with rock and sand to harden. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminium, iron and other ingredients.. Common materials used to The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular Manufacturing of Portland Cement Process and Materials
