Sand and Gravel. Sand and gravel deposits found on beaches or in rivers and streams, are mostly quartz (silicon dioxide, SiO 2) grains. Weathering of rocks such as granite forms these quartz grains. In the process of weathering, the softer, weaker minerals in granite (such as feldspar) are weathered away.

The physical properties of aggregates stem from the inherent properties of the source rock; these include texture, structure, and mineral composition. Textural properties give rise to internal characteristics, of which the pore size is perhaps most important. Structural characteristics define the degree to which the minerals within the aggregate are segregated or oriented in one…
Physical Properties of Aggregate: Flakiness Index The flakiness index of aggregate is the percentage by weight of particles in it whose least dimension (thickness) is less than three-fifths of their mean dimension. The test is not applicable to sizes smaller than 6.3 mm. The flakiness index is taken as the total weight of the
is done for the physical properties of manufactured sand with the natural sand by conducting various tests on physical properties of fine aggregates. In this study tests on physical properties of fine aggregate are carried out in the laboratory for both natural sand and manufactured sand.
What Are the Physical Properties of Sand? Sand is primarily composed of finely granulated silica and, depending on its location, can include various rock, coral, shell or lava fragments. It is lightweight and easily transported by wind and water. Its composition directly affects its color, resulting in black, white, pink and green coloring.
Primary raw coarse aggregate (granite) and sand (crushed limestone) were used indifferent concrete mixes. 2.4 Use of Recycled Aggregates in Construction. Crushed sound and clean waste concrete of at least 95% by weight of concrete with typical total contamination lower than 1% of the bulk mass.
Aggregates in Concrete Concrete Technology 10 Rocks are classified according to origin into three major groups: 1. Natural Mineral Aggregates- Sand, gravel, and crushed rock derived from natural sources. (a) Igneous Rocks -formed on cooling of the magma (molten rock matter). Granite, basalt: hard, tough, strong Excellent aggregates
