Fly ash being a pozzolanic material is very often used to enhance the physical and mechanical properties of cement and concrete. Whereas, blast-furnace slag cement is used due to its low heat of hydration and high sulphate and sea water resistance. Researches indicate that fly ash geopolymers ...
The present study has been done by adding steel fibers to concrete in a view of improving the mechanical properties of SCC so that it can be applied in beam column joints. An ideal mix proportion was arrived at, as a result of repeated trials and specimens that were cast and cured. The...
The basic properties of aggregates, such as water absorption and specific gravity, mechanical properties, such as abrasion resistance, effect, and crushing values were considered. Workability of fresh concrete and strength parameters of hardened concrete, such as compressive strength and tensile strength...
