Effects of pulverized fuel ash on the moisture ...

1966). Pulverized fuel ash (PFA), whic ihs produced from the combustion of finely ground coal, is a dust containing between 50 an 7d0 % of particles of the same size as fine sand (Hodgso & Hollidayn, 1966). It seemed possible, therefore, that additions of PFA to soils which contained only a small pro-portion of fine sand could increase the AWC of

Alkali-silica reaction in concrete - Understanding Cement

ASR is caused by a reaction between the hydroxyl ions in the alkaline cement pore solution in the concrete and reactive forms of silica in the aggregate (eg: chert, quartzite, opal, strained quartz crystals). A gel is produced, which increases in volume by taking up water and so exerts an expansive pressure, resulting in failure of the concrete.
