How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
In this way, 10% of marble powder used in place of cement was appropriate quantity in concrete. It is observed that concrete of M25 grade, mixing with 10% of marble powder and 1% of polyethylene glycol - 400 gives optimum result when compressibility, split tensile strength and flexural strength tests were performed and examined for 7 and 28 days.
Roman concrete, also called opus caementicium, was a material used in construction in Ancient Rome.Roman concrete was based on a hydraulic-setting cement.It is durable due to its incorporation of pozzolanic ash, which prevents cracks from spreading.By the middle of the 1st century, the material was used frequently, often brick-faced, although variations in aggregate allowed different ...
