In this study the potential for using demolition aggregate for lean-mix
of cement concrete and geopolymer concrete are investigated. To reduce the
production cost of concretes and for reuse of demolished concrete, this study is
undertaken. The effects of incorporating demolished aggregates in low strength
and geopolymer concrete mixes, on physical and structural properties such as
water absorption, split tensile strength, compressive strength, etc., are
investigated. This paper identifies various influencing aspects related to the
use of demolished aggregates such as replacement level, aggregate sizes, as
well as mixing procedure, strength development over time, etc.. In the present
study, the lean concrete mixes were prepared in the ratio 1:6:8 with the cement
content of 175 and 200 kg/m?, and geopolymer mix with 3M, 4M, 5M and 6M molar
concentration. Systematic comparison was carried-out between different types of
lean cement concretes and geopolymer concretes, with the experimental test
results. - See more at:
