Influence of Kenyan phonolite manufactured sand on concrete performance

There is a shortage of river sand and a large number of phonolite deposits around Nairobi, Kenya, but the quality of manufactured sand made from phonolite is poor. In this paper, the effects of phonolite manufactured sand and river sand on the performance of C30 and C50 concrete are studied through...
