Concrete – Wikipedia

Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a lime-based cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement.

Chemical admixtures are the ingredients in concrete other than portland cement, water, and aggregate that are added to the mix immediately before or during mixing.

Concrete shrinks during the hydration process and has a tendency to crack, especially pea gravel mixes due to their high water content. This is called shrinkage cracking.

Chemistry. Non-hydraulic cement, such as slaked lime (calcium oxide mixed with water), hardens by carbonation in the presence of carbon dioxide which is naturally present in the air.

Water-to-Cement Ratio and Aggregate Moisture Corrections

Two of the most commonly specified requirements for concrete used in the manufactured concrete products industry are the design compressive strength (f’ c) and the maximum water-to-cement ratio (w/c).

Because the mixing occurs in the free space above the mixer floor, the wear on the liner plates is very low; the outer 70% of the lined surface is rarely touched by concrete.

Secondary Efflorescence. All masonry and concrete materials are susceptible to secondary efflorescence, including concrete countertops. Secondary efflorescence is most often caused by moisture or water vapor migrating through a concrete slab, bringing soluble salts to the surface of the concrete.
