Properties enhancement of recycled aggregate concrete

01/08/2018· Grinding can be mechanical grinding,selective heat grinding (involving microwave to heat up and weaken the original ITZs between the virgin aggregate and the BM, and subsequent mechanical grinding) (Bru et al., 2014), or heat grinding (very high temperature heating of RA prior to ball milling) (Ma et al., 2009, Tateyashiki et al., 2001). Bonded mortar may be removed by employing

THE IMPROVEMENT OF RECYCLED CONCRETE AGGREGATE A

Recycled Concrete Aggregate (RCA), derived from Concrete & Demolition waste generally consists of natural coarse aggregate and adhered mortar which makes it porous due to high mortar content, inhomogeneous and less dense [3,4]. The volume of the residual mortar in RA varies from 25% to 60% according to the size of aggregate.

rinsing of recycled concrete aggregate

Recycled concrete aggregate (RCA) is the designation used in BS 8500-2 for recycled aggregate principally comprising crushed concrete. Designations of recycled aggregate other than RCA are of lower quality and may contain significant quantities of masonry which would preclude or limit their use in structural concrete.

The Effect of Grinding Process on Recycled Cement Paste

14/01/2020· The use of recycled aggregate in new concrete requires a beneficiation process, which separates the natural aggregate from the attached cement paste/mortar. The clean natural aggregate is used as recycled aggregate, while the attached cement paste/mortar is of no use. As a result, the majority of concrete recycling studies focus on the recycled

Properties enhancement of recycled aggregate concrete

01/08/2018· In this study, the intrinsic properties of recycled coarse aggregates (RC), associated with bonded mortar, were modified with two different pretreatment techniques viz-a-viz HCl pretreatment and Na 2 SO 4 pretreatment, while maintaining a fixed aggregate-to-solution ratio of 1:4.5. The residual bonded mortar was quantified to evaluate the potential of both techniques.
