fine aggregate zone classification codes
Fine aggregates are the aggregates whose size is less than 4.75 mm.Example: Sand is used as fine aggregate in the preparation of concrete and cement mortar.
bulking of fine aggregate increases its volume. hence the mass for a given volume is less, which leads to richer mix than required. therefore batching of fine aggregate must be done by weight and not by volume.
60 % throughout in B.Tech Aggregate firstly...... However it was reduced to 55% in 10th, 12th and B.Tech Aggregate.
Cement mortar is a mixture of cement, fine aggregate and water.Concrete is a mixture of cement, fine aggregate, coarse aggregate and water.Generally, concrete have higher strength than cement mortar.
mix ratio is 1 : 2 : 4 cement : fine aggregate : course aggregate
rock crushing
The specific gravity of fine aggregate typically ranges from 2.60 to 2.80. This range can vary depending on the mineral composition and moisture content of the aggregate. Specific gravity is an important property that influences the weight, volume, and overall performance of concrete mixtures.
