Take the required amount of aggregate sample (for a sand (fine aggregate) minimum of 0.5kg sample is required. Arrange the required no of sieves as per the contract or job requirement in a descending manner. (i.e. keep the sieve having the largest size opening at the top and the smallest size opening at the bottom)
Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. The composition of Sand varies, depending on the local rock sources and conditions, but the most common constituent of Sand is silica (silicon dioxide, or SiO 2 ), usually in the form of quartz.
2.2. Fine Aggregate Tests. As discussed earlier, the grading of the fine aggregate is an important factor that influences the performance of concrete, therefore all fine aggregates were tested for particle size distribution according to BS EN 933-1:1997.
Screening is the separation of material into 2
The fine aggregate will typically consist of natural sand, crushed stone sand, crushed gravel sand stone dust or arable powder, fly ash, and broken brick (burnt clay). It will be hard, durable, chemically inert, clean and free from sedimentary coatings, organic materials, etc. and will not contain any appreciable amount of clay shells or pellets and harmful impurities.
Secondary Screening. V’Sepa air screen installed as a secondary screen in a quarry to accurately screen coarse aggregate while removing ultra-fine dust. The dry washing process removes the need for water in the secondary screen. Input Example: 0-40mm quarry rock with less than 1.5% moisture. Output Example:
Concrete is a mixture of cement, coarse aggregates, fine aggregates or sand and water. The approximate ratios of these components are as below: Based on the ratios and the anticipated cement consumption in the country, the expected requirement of sand will be about 500-550Mt in the next few years or so.
Gravel sand refers to a sand which content of gravel grain in sand stone that account for 25% to – 50% in total quality (particle size > 2 mm). The standard of sand used in architecture: refers to rock fragments that its particle sizes < 5 mm , form and accumulate in natural waters such as lakes, seas, and rivers.

Chieftain 1400 Wheeled. The Chieftain 1400 Wheeled Inclined Screen is one of Powerscreen’s most popular screening products. The machine is ideal for small to medium scale production and is versatile enough to meet the screening needs of many applications. This inclined screen thrives in aggregates, sand and gravel, and recycling applications.
fine aggregate loosely in the mold, filling it until overflowing occurs, and heaping additional material above the top of the mold. Lightly tamp the fine aggregate into the mold with 25 light drops of the tamper. Each drop should start about 0.2 inch above the top surface of the fine aggregate.
Sand is a granular material composed of minerals and rock sediments. What is sand used for? The purpose of sand are various. Sand can be used independently, or as a blend product. The main purposes are for sandboxes, playgrounds, grouting between tiles or blending it with earth. Sand is for instance an important raw material in the construction
The Sand Equivalent Test Procedure. A prepared sample of fine aggregate is added to a working solution of calcium chloride and glycerin in a unique graduated cylinder. The cylinder is agitated in a prescribed manner, either manually or by a mechanical shaking device. After agitation, a metal irrigation tube is manually worked into the sample

Coral sand, glass sand, gypsum sand, silica sand, river and sea sand, green sand, desert sand, heavy mineral sand, and volcanic sand, etc. Stone Screening: By screening crushed stones stone screening is obtained and are fine particles and in batter strength, to concrete, the grains are strong and sharp.

The silt content determination for fine aggregate by volume is done in the following manner: The glass cylinder is filled with a saltwater solution (concentration of the solution will be teaspoon full of common salt for every 570ml) up to 50ml mark. Add sand (fine aggregate) until the level of the sand is up to the 100ml mark.
