Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates.

What goes into the most commonly used building material? Concrete is a mixture of cement, air, water, sand, and gravel–it's as simple as that! Not exactly. The typical concrete mix is made up of roughly 10% cement, 20% air and water, 30% sand, and 40% gravel.

Cement requires a closely controlled combination of raw materials, including calcium, silicon, iron and aluminium. Common materials used to manufacture cement include limestone, shells, and chalk or marl, combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.

It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 2 to 3 percent of gypsum. Several types of Portland cement are available. The most common, called ordinary Portland cement (OPC), is grey, but white Portland cement is also available.

Portland cement, known also as hydraulic cement, is a finely ground, grayish powder used as a binding material and made from pulverized and burned limestone and clay or limestone and shale mixtures. Plastic cement, a flexible, water-resistant sealant, is made from portland cement.

Concrete is a mixture of cement, air, water, sand, and gravel–it's as simple as that! Not exactly. The typical concrete mix is made up of roughly 10% cement, 20% air and water, 30% sand, and 40% gravel. This is called the 10-20-30-40 Rule–though proportions may vary depending on the type of cement and other factors.

The composition of cement is GaO (lime) or limestone 62% silica (SiO2) 22% alumina (Al2O2) 7.5%, magnesia (MgO) 2.5 % etc. thus, limestone is the major raw material for cement.
