How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed ofportland cement and water,coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction calledhydration, the paste hardens and gains strength to form the rock-like mass known as concrete. Within this process lies the key to a remarkable trait of …Get Price
Sep 11, 2017·CEMENT CONCRETE. It is a composite material where in a pasteof cement, made with water, on solidification binds firmly together the various particles of inert materials like sand and stone ballast.The inert material called “aggregate” is well graded in size from fine sand to pebbles or stone ballast or brick ballast.Cement concreteis an extremely versatile material of construction which ...Get Price
