In contrary, a lower specific gravity of sand will result in lower density of concrete. The specific gravity of fine aggregates found in Pune region varies from 2.6 to 2.8. 4. Silt Content. This is found by wet-sieving of sand and material passing 75-micron sieve is classified as silt.

Concrete is an artificial stone manufactured by mixing together coarse and fine aggregates, cement, water and often other components such as cement replacement materials, e.g., pulverised fuel ash, and chemical admixtures, e.g., superplasticisers. The grading of an aggregate defines the proportions of particles of different size in the aggregate.

used as the replacement of fine aggregate in the concrete. Concrete cubes were cast taking 10%, 20%, 30 %, 40% & 50% of plastic as partial replacement of fine aggregate and tested for 7 & 28 days of compressive strength of concrete.

AGGREGATES FOR CONCRETE E1-3 sieve and predominantly retained on the 75 µm (No. 200) sieve is called "fine aggregate" or "sand," and larger aggregate is called "coarse aggregate." Coarse aggregate may be available in several different size groups, such as 19 to 4.75 mm (3/4 in. to No. 4), or 37.5 to 19 mm (1-1/2 to 3/4 in.).

For conducting the tests, initially a portion of conventional fine aggregate (i.e. sand) was replaced by equal proportions of ceramic and surkhi powder till all of fine aggregate got replaced. The results obtained from various tests conducted on concrete of grade M25 were analyzed and ultimately compared to that of the standard M25 grade.

partial or full replacement of fine aggregates. Fine aggregate was replaced with CCB by weight up to 100 % at intervals of 10%. The properties investigated were: workability, density and the compressive strength. The slump test and the compacting factor test were used to assess the workability of the concrete sample specimens.

Alternative materials for coarse aggregate in concrete can be rubber, glass, expanded fly ash clay, or plastic materials. On the other hand, agro-wastes, to industrial by-products, alternative materials for fine aggregate in concrete can be of a wide variety. In the following section, you will get a brief idea on these aggregate alternatives.

waste copper slag as replacement material of fine aggregates in concrete. Mix proportion has to be done for M25 grade of concrete with water cement ratio 0.50. The fine aggregate is replaced with copper slag in proportions of 0%, 20%, 30%, 40%, 50%, 60%, 80%, and . Tests were performed for properties of fresh concrete and hardened concrete.

aggregates cannot be overemphasized. The fine and coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influ-ence the concrete's freshly mixed and hardened proper-ties, mixture proportions, and economy. Fine aggregates (Fig. 5-1) generally consist of natural sand or crushed
