Concrete Blocks Raw Material. Lightweight concrete blocks are made by replacing the sand and gravel with expanded clay, shale, or slate. Expanded clay, shale, and slate are produced by crushing the raw materials and heating them to about 2000°F (1093°C). At this temperature the material bloats, or puffs up, because of the rapid generation of

For normal concrete and HSC, the concrete compressive strength test results from cube specimens are generally higher than cylinders specimens [6]. As states in BS 1881, the compressive strength of concrete gained by cylinder specimens is equal to 0.8 times of the compressive strength gained by cube specimens.

Building sand responds well to cement in order to form high-end concrete bricks. But you have to remember mixing with crushed stone to create a less smooth surface on the bricks/blocks, which will make plastering grip much better for a longer lasting wall surface. Adding the stone partickes will also increase the brick strength.
