“…The effectiveness of EPP in mitigating ASR can be attributed to pozzolanic activity [6,7], possessed by the material. In suppressing expansion, the porous nature of EPP might play an important role by providing a distributed air bubble system that accommodates expansive gel in concrete [7]. Furthermore, G.E.…”

Abstract. ASR suppression by FA, SF, EPP, FA in combination with SF and EPP were evaluated by both mortar bar and concrete prism test. Mortar bars were made based on JIS A 1146, meanwhile concrete prism bars were casted in accordance with Rilem AAR-3. Both specimens were stored in 40 o C 100% R.H. controlled room. Mortar and concrete mixtures used reactive aggregate in pessimum proportion. The results indicated that FA in combination with SF and EPP showed smaller expansion compared to FA. The best of concrete mixtures in reducing expansion is combination of FA with SF (FA15SF10).

“…This fact may be related to water uptake due to the high surface area gained by these additives. EPP could be used in small quantities as a cement replacement due to its high water absorption capacity [34]. However, in case of CS there is a slight decrease with increase dosages and density that means CS did not have the ability to excess water uptake.…”

“…A number of researchers have shown that the ASR expansions can be controlled by using sufficient natural and artificial pozzolans, such as perlite powder (PE), pumice powder (PU), zeolite powder (ZE), fly ash (FA), brick powder (BP) and silica fume (SF) (Ahmadi and Shekarchi, 2010;Andiç-Ç akır et al, 2008;Bektas and Wang, 2012;Bektas et al, 2005;Demir, 2010;García-Lodeiro et al, 2007;Gupta, 1992;Khandaker, 2005;Quanlin and Naiqian, 2005;Ramyar et al, 2004;Thomas et al, 1999Thomas et al, , 2006Thomas et al, , 2007Thomas et al, , 2011Turanli et al, 2003).…”

In this study the effects of natural and artificial pozzolans on alkali-silica reaction expansion of mortars were investigated by using the accelerated mortar bar test method in accordance with the ASTM C 1260. For this purpose, four natural pozzolans -ignimbrite powder (IG), perlite powder (PE), pumice powder (PU) and zeolite powder (ZE) -were used as cement at replacement levels of 0, 5, 10, 15, 20, 25, 30, 35 and 40% by weight of ordinary Portland cement. Four artificial pozzolans -fly ash (FA), brick powder (BP), silica fume (SF) and aerated concrete powder (AP) -were used at replacement levels of 0, 5, 10, 15, 20 and 25% by weight. The expansions of mortar bars were reduced as the replacement ratios of each natural and artificial pozzolans were increased, with the exception of specimens with a replacement level of 15, 20 and 25% AP. It is determined that at comparable replacement ratios SF is the most effective among the pozzolans used and is followed by PU, ZE, IG, PE, FA, BP and AP respectively.
