Concrete - 1 part cement, 2 parts concreting sand and 3 parts 20 millimeter aggregate. Mortar - 1 part cement, 4 to 5 parts building sand.
Natural sand has eroded from mountain rock and is mined from where it was deposited. The host rock determines the exact mineral composition, but most sand is composed of silica from broken down quartz crystals. This type of sand is extremely resistant to weathering and breakdown due to its chemical hardness and will last longer as arena footing.
Silica Sand. This was once the most popular type of paver sand, but it had many disadvantages. The sand was generally placed between the pavers after fitting, and this improved the fitting of the pavers, but it had to be kept stable by adding a sealant over the top, and was often washed away during storms.
