Depending on the deposit and variety quarry sand fraction varies in the range of 1.5–5 mm.According to this parameter, the varieties are divided into small-medium and large-fraction species. Particle size determines the type of use and is especially relevant for mixing with cement.
Crushed Stone Sand. It looks like gravel and feels like gravel. But unlike gravel, crushed stone sand is a natural but commercially created resource that is made from crushed minerals, such as granite or limestone. Crushed stone sand is commonly used for road construction, and is widely known as a low-cost, high-value commodity.

The proportion of 25% laterite to 75% quarry dust and 50% laterite to 50% quarry dust with 0.6 water cement ratio produced workable concrete with good structural characteristics; iii) The density of hardened concrete using lateritic sand and quarry dust was found to range from 2293-2447 Kg/m3.
The density is typically measured in kilograms per cubic meter (kg/m3) or pounds per cubic foot (lb/ft3). To determine it, a specific volume of sand is weighed and then divided by the volume it occupies. The volume can be determined using a container with a known volume or by measuring the displacement of water when sand is placed in it.

Fees and costs. In addition to the application fee and an annual land rent, royalties on extracted materials are charged: An annual land rental for a lease or a licence is based on 1% of Appraised Market Land Value, with a minimum rent of $675 per year. Additional rental is charged for secondary uses associated with the operation.
The quarry dust was supplied by factory ID Interlocking Brick Sdn Bhd., Terengganu. The specific gravity of quarry dust was 2.69 and the fineness modulus was 2.8 with density of 1,630 kg/m 3. The quarry dust of size 6 mm after sieving was used. The quarry dust was then dried in the room temperature before used.
Density is also called as unit weight of substance. It is represented by symbol called row ( p). Density represents the degree of compactness of material. If the material is of more density, it is more compacted material. Density is defined as the ratio of mass to volume. p = m/v Units = kg/m 3 or lb/ft 3 Conversion: 1 kg/m 3 = 0.624 lb/ft 3.
mix was maximum at quarry dust and increase in strength was about 14% and 11% respectively compared to normal concrete. Water absorption of lateritic sand is 4% by weight and quarry dust is 2% by weight. So super plasticizer (Forsoc conplast 430) of optimum 1.5-3% is used to get desired workability.
