Recycled geopolymer aggregates as coarse

2020-3-10  Grading of coarse natural basalt aggregates, recycled geopolymer aggregates (RGA) and recycled PCC aggregates obtained after crushing, prior to remixing. The average 24-h water absorption (ASTM C127) [58] and specific gravity (ASTM C127) [58] of graded coarse aggregates were measured to be respectively 6.4 ± 0.2 and 2.26 ± 0.20 for RGAs, and

Mechanical Properties of Recycled Aggregate

This paper presents an experimental research on mechanical properties of recycled aggregate concrete (RAC) at low and high water/binder (W/B) ratios. Concrete at two W/B ratios (0.255 and 0.586) was broken into recycled concrete aggregates (RCA). A type of thermal treatment was employed to remove mortar attached to RCA. The RAC at a certain (low or high) W/B ratio was prepared with RCA made

Use of Recycled and Waste Materials in Cement Concrete

2019-9-2  aggregate and 3 parts of coarse aggregate were used to prepare concrete mix. In mix proportion silica fume and fly ash were used as cement replacements on a weight basis. In all concrete mix a constant water to binder ratio 0.5 was used except the concrete mix prepared with recycled aggregate subjected to variations in water-cement ratio.
