Mix Design and Properties of Recycled Aggregate

2014-8-26  At fresh state, the mix design of concrete with recycled aggregates requires an additional quantity of water to obtain a similar workability as a concrete formulated with natural aggregates (Hansen and Boegh 1986). Such a modification may obviously affect the mechanical characteristics of recycled aggregates concrete.

Concrete Mix Design for Completely Recycled Fine

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 ...
