Specific gravity of cement, fine aggregate and crushed ceramic tile are 2.63, 2.65and 2.50 respectively. It was observed that 10% at 0.5w/c of replacement has higher water absorption rate of 1.14% and 5% at 0.5w/c of replacement has lower water absorption rate 0.88%. ...

Use of aggregates with low specific gravity such as shale, sandstone and chert can produce poor performance in concrete, ... a maximum 1.0% of a coarse aggregate to be comprised of materials finer than 80 µm which can be relaxed 2.0% for crushed aggregate provided that the fine material is the dust of fracture and free from clay or shale.

5.2 Relative density is used to calculate the volume occupied by the aggregate in various mixtures containing aggregate, including hydraulic cement concrete, bituminous concrete, and other mixtures that are proportioned or analyzed on an absolute volume basis. Relative density (specific gravity) is also used in the computation of voids in aggregate in Test Method …

of particle size distribution carried out on the aggregates (fine and coarse – crushed granite stone, limestone and marble stone) are presented in Table 1. 2.2.2 Specific Gravity Specific gravity (G s) is generally defined as the ratio of the mass of a given volume of material to the mass of an equal volume of water at the same temperature.

Properties of aggregates such as bulk density, specific gravity, voids, water absorption and its values are presented in this article. 1. Aggregates: Bulk Density, Specific …

The relative density (specific gravity) of an aggregate is the ratio of its mass to the mass of an equal volume of water. Relative Density = Mass of the Aggregate / Mass of equal volume of …

The parameters tested are flow time based on New Zealand flow cone, loose bulk density, uncompacted voids and specific gravity. In order to enhance the performance of the poor crushed sand, different samples of crushed sands were blended which ... concrete mix made with aggregates such as crushed aggregates which generally have higher specific ...

Recommended Values of Specific Gravity and Water Absorption for Aggregates The specific gravity of aggregates normally used in road construction ranges from about 2.5 to 3.0 with an average of about 2.68. Water absorption shall not be more than 0.6 per unit by weight.

material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi- mately 60 to 75% of the volume of concrete.

identification of stone. The specific gravity of aggregates ranges from 2.5 to 3.0.Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. Water; at a temperature of 73.4'C (23'C) has specific gravity .Specify gravity is important for several reasons.

It is used for concrete mix design and if not specified the specific gravity is taken as 2.7 because the specific gravity of most aggregates obtained from different sources falls between 2.6 and 2.8.. 5.Surface Texture of fine aggregates: Generally, round surface aggregates are better for smooth aggregates, this property is also related to coarse aggregate.
