How Fine Aggregates Afeects Concrete Mix Design

How Fine Aggregates Afeects Concrete Mix Design

Fine aggregate is on of the major constituents of concrete which can influence concrete mix design substantially. Various factors such as fine aggregate fineness modulus moisture content specific gravity and silt content affect the mix proportions of concrete. Fineness modulus specifies how much fine aggregate is required in a given mix design.

Use Of Coal Waste As Fine Aggregates In Concrete

Use Of Coal Waste As Fine Aggregates In Concrete

The concrete paving blocks were produced in a ver- tical shaft concrete mixer. The reference trace used 5.36 kg of cement 6.26 kg of coarse basaltic aggregate 14.18 kg of river sand aggregate and a watercement ratio of 0.39. The coal waste was used as a substitute for river sand aggregate considering the following volumetric

Aggregates Cement

Aggregates Cement

For a good concrete mix aggregates need to be clean hard strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates which account for 60 to 75 percent of the total volume of concrete are divided into two distinct categories--fine and coarse.

Concrete Mix Design For Completely Recycled Fine Aggregate

Concrete Mix Design For Completely Recycled Fine Aggregate

The undesirable properties of conventional recycled fine aggregate RFA often limit its application in the construction industry. To overcome this challenge a method for preparing completely recycled fine aggregate CRFA which crushes all concrete waste only into fine aggregate was proposed. The obtained CRFA had high apparent density and its water absorption was lower than that of the .
