13 Different Types of Concrete Blocks - Home Stratosphere

Often confused with concrete bricks, aerated autoclaved concrete blocks are composed of the same aggregates as bricks, but the composition or mixture varies, resulting in a larger yet lighter version.This quality has enabled a significant reduction in cost. Plus, research suggests that its high durability has led to a reduction in the overall consumption of steel by 15% and concrete by 10%.

concrete | Definition, Composition, Uses, Types, & Facts

Concrete is characterized by the type of aggregate or cement used, by the specific qualities it manifests, or by the methods used to produce it. In ordinary structural concrete, the character of the concrete is largely determined by a water-to-cement ratio. The lower the water content, all else being equal, the stronger the concrete.
