Aggregates for Concrete

Recycled concrete, or crushed waste concrete, is a feasible source of aggregates and an economic reality, especially where good aggregates are scarce Conven-tional stone crushing equipment can be used, and new equipment has been developed to reduce noise and dust Aggregates must conform to certain standards for optimum engineering use: they must be clean, hard, strong, durable particles free .typical white concrete" It also reports default SRI values for new gray and new white concrete of 35 and 86, , was made for the absorption of the aggregat Some of the specimens therefore had insufficient mixing water, the finished surfaces were irregular, and it was difficult to obtain reliable reflectance results For specimens produced using concrete mixtures with sufficient mixing.

Crushed Concrete Aggregates

Crushed concrete aggregates also called as recycled concrete aggregates are fragments and pieces of concrete buildings which are demolished or rebuild These crushed concrete are cleaned from dirt and broken to smaller pieces to manufacture aggregate which is termed as recycled aggregateHigh absorption is particularly noticeable in crushed fine material, which is less than 475 mm in size (minus No 4 sieve size), and particularly in material from air-entrained concrete (since there is substantially more air-entrained mortar in the fine than the coarse RCM aggregates) The minus mm (No 200 sieve) fraction is usually minimal in the RCM product Some typical physical.
