Sharp sand, also known as concreting, coarse or grit sand contains a greater proportion of larger particles than builders or soft sand. As a result it is best used as part of the base underneath driveways, patios, artificial grass or block paving where a layer of hardcore or MOT is used then topped with a layer of sand and compacted for a smooth level surface.

The best concrete mix for footings is actually pretty easy to make. It's 1 part Portland cement, 2 parts sand and 4 parts stone aggregate by volume. Add in 3 quarts water per 80 pounds of dry concrete. Aggregate should be between 1/2 – 1 inch in size. That's it. Concrete is a fantastic building material that's very easy to make.

For common batching proportions, 1 ton (2,000 lb, 907 kg) of masonry sand is required for every 8 bags of masonry cement. If more than 3 tons (2,721 kg) of sand is used, add ½ ton (454 kg) to account for waste. For smaller sand amounts, simply round up to account for waste. This equates to about 240 concrete masonry units per ton of sand.

 · Concrete viscosity is measured by "slump" which refers to a specific test where the amount that a cone filed with concrete will lose its shape once the cone is removed is measured in inches or mm. A concrete with zero slump would be very rigid and dry and inclined to hold its shape, where a concrete with a slump of six inches or more would be extremely wet and not inclined to hold a shape.

Aggregate definition and Shape, Types, Properties. Aggregates occupy 70 to 80% of the volume of concrete. Physical characteristics and in some cases, the chemical composition of aggregates affect the properties of concrete in its plastic and hardened state. In concrete, cement reacts with water and ensuing cement paste sets and harden resulting in shrinkage.
