Recycled materials, such as post-consumer glass, slag cement, or recycled aggregate, are often used in the composition of the blocks.

Lower-density blocks may use industrial wastes, such as fly ash or bottom ash, as an aggregate. They also have an added decorative effect to certain types of block, such as split-face, due to their distinct red and black colors. In the western United States, where they are easily obtainable, porous lava rock gravels are used for weight reduction. portland cement and aggregate, usually sand and fine gravel, for high-density blocks). Composition Ĭoncrete blocks are made from cast concrete (e.g.

Ĭlinker blocks use clinker (ash created as a waste product from impurities in minerals such as coal, limestone and iron-ore), also called slag. In Australia, they are often known as besser blocks (because the Besser Company was a major supplier of machines that made concrete blocks), and also as grey blocks or concrete masonry units (CMUs). However in the United States breeze blocks also refer specifically to decorative blocks used on exterior walls to allow the breeze through, which were an important feature of Mid-Century Modern design. They are also known as 'breeze blocks', a term derived from 'breeze', referring to the small cinders and cinder-dust that are by created partially burned coal. Those that use cinders ( fly ash or bottom ash) as an aggregate material are called 'cinder blocks' in the United States. The use of blockwork allows structures to be built in the traditional masonry style with layers (or courses) of staggered blocks.Ĭoncrete blocks may be produced with hollow centers (cores) to reduce weight, improve insulation and provide an interconnected void into which concrete can be poured to solidify the entire wall after it is built.Ĭoncrete blocks are some of the most versatile building products available because of the wide variety of appearances that can be achieved using them.

Modern reinforcedĬoncrete can contain varied reinforcing materials made of steel, polymers or alternate composite Of the concrete that might cause unacceptable cracking and/or structural failure. Reinforcing schemes are generally designed to resist tensile stresses in particular regions Reinforcing bars (rebar) and is usually embedded passively in the concrete before the concrete The reinforcement is usually, though not necessarily, steel Low tensile strength and ductility are counteracted by the inclusion of reinforcement having Reinforced cement concrete or RCC is a composite material in which concrete's relatively The mixture of cement, fine aggregate (sand) and coarse aggregate and reinforcement to increase its compressive and tensile strength are generally called Reinforced cement concrete (RCC). The term RCC stands for Reinforced cement concrete.
