Structural lightweight aggregate-Structural aggregate meeting the requirements of ASTM C 330 with bulk density less than 70 lb/ft³ (1120 kg/m³) for fine aggregate and

Standard Test Method for Determining the Relative Density

4.1 Bulk relative density (specific gravity) is the characteristic generally used for calculation of the volume occupied by the aggregate in various mixtures containing aggregate including Portland cement concrete, bituminous concrete, and other mixtures that are proportioned or analyzed on an absolute volume basis. Bulk relative density (specific gravity) is used in the computation of voids ...

Replacement of Fine Aggregate by M-Sand

Coarse aggregate can be defined as inert granular materials such as gravel, crushed stone and sand. Coarse aggregate is one of the essential ingredients apart of water and cement in concrete production. It consists about 60 to 75 percent of total concrete production Coarse aggregate comes from particles greater than 4.75mm but commonly in a range between 9.5mm to 37.5mm. Fine Aggregate Locally available river sand …
