In this study, we have used grit and crushed sand for the design mix and found the characteristic compressive strength at 3,7 and
Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categoriesfine and coarse. Fine aggregates generally consist of natural

For the concrete with crushed coarse aggregate, calculate the percentage of fine aggregate in total aggregate by absolute volume from the table. 6. For any
According to BS 8007, aggregates should comply with either BS 882 or BS 1047 and have an absorption, as measured in accordance with BS 8122, generally not greater than 3%. The Civil

Sahu et al. (2003) observed that concrete made using crushed rock sand attained the comparable compressive strength, tensile strength and modulus of rupture as the control concrete. Sahul Hameed and Sekar (2009) concluded that the compressive strength, split tensile strength and the durability properties of concrete made of quarry

They prepared the concrete mixes based on Bureau of Indian Standards, ACI and British codes by using crushed rock sand and natural river sand as an ingredient.

The effect of the heating temperature on the strength of concrete cubes produced without inclusion of crushed glass, as control specimen, and concrete cubes containing crushed glass content as sand replacement in percentage levels of 0–100% are shown in Fig. 5. The results show that there is clearly decrement in the compressive
B. Balapgol, S. Kulharn, K.Bajoria (2002), investigated the use of crushed sand as fine aggregates along with fly ash in concrete. They says that a combination of fly ash and crushed sand yield a far superior concrete mix than crushed sand alone. Hadassa Baun and Amnon Katz (2009) studied the percentage of fines in crushed sand and its

While using crushed stone dust as fine aggregate in concrete it is found that there is increase in compressive, flexural and tensile strength of concrete (Nagpal et al., 2013).

The Concrete has been traditionally made with use of Natural / River sand as fine aggregate. As sand contributes to around 25 to 35% of total concrete along with coarse aggregates, cement & water, the properties of the fine aggregates would be one of the major influencing factor in determining the fresh & hardened Concrete properties and
