MECHANICAL PROPERTIES OF HIGH-PERFORMANCE CONCRETE PRODUCED IN SUDAN
Abstract
compressive strength exceeding 80 MPa. Research includes use of mineral admixture (silica fume) and Aggregates(Crushed stone and quartz sand).
Effect of different level of silica fume replacement of cement by 0, 15, 20 and 30% on main properties of HPC, i.e., compressive strength, density and slump were investigated. Test results revealed that it is possible to produce HPC in
Sudan, with compressive strength in excess of 80 MPa using materials which are available at local markets, if carefully selected and mixed in such a way as to give optimum distribution of granules. Optimum percentage of silica fume
necessary for producing HPC is about 20 % of cement weigh.
