can be a replacement for fine aggregate. Which lead s to a cost reduction for making of concrete. Which can be get easily from quarry waste, so that we can check the workability and strength of the concrete. If it sat isfies the normal concrete quality and strength in we can use it as the replacement for the fine aggregate[14].Continues r esearch

Aggregate Blending, Absorption Specific Gravity 20 Fine Aggregate Specific Gravity Calculations Example Problem Given A = mass oven dry = B = mass of pycnometer filled with water = C = mass pycnometer, SSD aggregate and water = S = mass SSD aggregate =

aggregate per unit volume of concrete is selected, for the particular maximum size of coarse aggregate and fineness modulus of fine aggregate. The weight of per cubic meter of concrete is calculated by multiplying the bulk volume with bulk density. From Table, for 20 mm coarse aggregate, for fineness

Using aggregate makes concrete much stronger, with the aggregate acting as a type of reinforcement. The aggregate increases the lifetime of the concrete, and makes it more durable. Contractors can choose from fine aggregates, made from small particles of material, and coarse aggregates, which are made with large chunks.

concrete increases with an increase in coarse aggregate content until a critical volume is reached, while Bayasi and Zhou (1993) found little correlation between .

Fine aggregate is the essential ingredient in concrete that consists of natural sand or crushed stone. The quality and fine aggregate density strongly influence the hardened properties of the concrete.. The concrete or mortar mixture can be made more durable, stronger and cheaper if you made the selection of fine aggregate on basis of grading zone, particle shape and surface texture, abrasion ...

Lightweight aggregates: As mentioned in the body of this paper, lightweight concrete contains aggregate that is natural or synthetic which weighs less than 1100 kg/m lightweight is due to the cellular or high internal porous microstructure, which gives this type of aggregate a .
