What Is Concrete Blocks?
Spread the cement over the sand and add aggregates. Use a shovel to mix the sand and cement until a uniform colour is achieved. Sprinkle water over the surface of the mixture. Continue to mix until the correct consistency of concrete is reached.
The Process Of Mixture For Concrete Blocks
The standard mix for Concrete Blocks is 1:3:5, 1 part cement to 3 parts sand & 5 parts stone aggregate, by volume. 1 part cement to 8 parts mixed aggregate is much the same thing. Note that the ratio is different by weight, since the ingredients don’t have the same density. Many other mixes are also possible.
