Concrete is a heavy, rough building material made from a mixture of broken stone or gravel, sand, cement, and water that can be spread or poured into molds and that forms a stone-like mass on hardening. However, concrete is a very brittle substance and possess a low tensile strength or resistance to horizontal forces such as expansion or contraction. Aggregates comprise 60 to 75 percent of the total volume of concrete. Cement is the glue that holds the materials of the concrete together. 'Cement' vs. 'Concrete' This distinction is not a new one; we have citations from over a century ago in which writers take care to observe (or admonish) that concrete and cement are not synonymous (the reasoning being that cement is one of the parts of concrete)..

If people have been distinguishing between these words for well over a hundred years, millions of dollars in advertising money has been spent, innumerable angry letters and tweets composed, why is it that we still define cement as “concrete”? Concrete has a high, compressive strength meaning it can withstand vertical forces. In its simplest form, concrete is a mixture of paste and aggregates (sand & rock). Relatively thin buildings sections can require small coarse aggregates, though aggregates up to six inches (150 mm) in diameter have been used in large dams. Concrete, on the other hand, is a relative newcomer (at least in the sense that is under dispute). ©2021 Concrete Contractors Association of Greater Chicago.

Cement is a unique adhesive agent make it an excellent binding component, but on its own, cement is prone to cracking. Besides portland cement, concrete may contain other cementitious materials including fly ash, a waste byproduct from coal burning electric power plants; ground slag, a byproduct of iron and steel manufacturing; and silica fume, a waste byproduct from the manufacture of silicon or ferro-silicon metal. Cement, when mixed with water, will form a paste that will harden. A properly proportioned concrete mixture will possess the desired workability for the fresh concrete and the required durability and strength for the hardened concrete. Excessive impurities in mixing water not only may affect time and concrete strength, but also may cause efflorescence, staining, corrosion of reinforcement, volume instability and reduced durability. It is strong and more durable than the other cement or mortar alone. Concrete Vs Cement.
