Concrete Design Production. Concrete is a mixture of two components: aggregates and paste. The paste, comprised of cement and water, binds the aggregates (usually sand and gravel or crushed stone) into a rocklike mass as the paste hardens. A properly proportioned concrete mix possesses acceptable workability of the freshly mixed concrete and ...
Advantages of Masonry Construction. These general advantages apply for all types of masonry units (brick, stone or concrete blocks): Masonry is noncombustible, so improves fire protection for the building and its occupants. Fireplaces are commonly made of masonry for the same reason.
is not feasible or desirable. The characteristics of concrete containing fine crushed glass during its process, the best ratio of fine crushed glass which leads to higher strength of concrete in order to produce concrete blocks, and the effect of waste glass replacement on the expansion caused by Alkalisilica reaction (ASR).

1. What is the difference between a metric and an imperial block? Prior to 1979, all concrete blocks manufactured in Canada were based on the following imperial dimensions height of 8", length of 16", widths ranged from 4" to 12". However, the actual dimensions of the blocks were 75/8" by 155/8" by between 35/8" and 115/8" to
