Effect of cut-size particles on the pozzolanic property of bottom ash

In this study, river sand that had a quartz content of up to 84.76% (the remaining 15.24% was microline) was selected for evaluating the reactivity. Moreover, the river sand and GBA had the same fineness, namely, 95 ± 1% of the particles passed through a No. 325 sieve (with an opening size of 45 microns), to reduce the packing effect due to ...
