Recycled aggregates: Guidance for producers and purchasers

Recycled aggregates: Guidance for producers and purchasers Introduction Issues addressed Index Page 2 Page 2 Page 3 The characteristics that make an aggregate suitable for a specific construction application are set by the designer [s engineering specification The specification stipulates the relevant aggregate product standard and will use the standard [s classes and categories to setIn terms of morphological characteristics, recycled aggregate is less favorable than natural aggregate The grains are irregular, mostly with angular shape, rough and with cracked surface and porous These grain characteristics grains significantly affect the workability of fresh concrete, as well as the permeability of liquids and gases in the hardened state; they also significantly depend onPROPERTIES OF RECYCLED AGGREGATE CONCRETEPore characteristics of recycled aggregate concrete and Feb 22, 2021 The recycled coarse aggregate came from the same batch of abandoned concrete structures, and the strength grade of the primary concrete was about C30 The porosity and density of recycled coarse aggregate were 1141% and 2573 kg/m 3, respectivelyget price Author: Jiangang Wang, Jinxi Zhang, Dandan Caocharacteristics of recycled aggregate
