The objective of this experimental study was to use ground clay brick (GCB) as a pozzolanic material to minimize the alkali-silica reaction expansion. Two different types of clay bricks were finely ground and their activity indices were determined. ASTM accelerated mortar bar tests were performed to investigate the effect of GCB when used to replace cement mass. The microstructure of the mortar was investigated using scanning electron microscopy (SEM). The results showed that the GCBs meet the strength activity requirements of ASTM. In addition, the GCBs were found to be effective in suppressing the alkali-silica reaction expansion. The expansion decreased as the amount of GCBs in the mortar increased.

• Effect of particle size on alkali–silica reaction in recycled glass mortars (2014, unknown): “A number of studies [12,34–39] have established the ASR suppressing mechanism of pozzolanic reaction, which results in: (a) enhanced impermeability of cement paste and hence reduced mobility of ions; (b) reduced alkalinity of the pore solutions as a result of depletion of cement; (c) reduced amount ”
