This work investigates the effect of olive waste ash (OWA) on the durability of concrete exposed to alkali-silica reaction (ASR). Three OWA contents were considered in the work: 7, 15 and 22 %, with crushed Pyrex glass used as reactive fine aggregate. The other experimental parameters investigated in the study were: w/c ratio (0.4 and 0.5) and air content (non-air-entrained and air-entrained). The OWA concrete specimens were submerged in 1-N NaOH solution at 40 °C to accelerate the ASR. The ASR damage was monitored by measuring the expansion of concrete prisms and the decrease in compressive strength. |
