Experimental Investigation on the Strength of Concrete with Partial Replacement of Cement using GGBS and Alccofine
Abstract: Cement is the most important ingredient of concrete. A large scale production of cement consumes large amount of energy and produce a large amount of carbon dioxide (CO2) gas which harmful to human as well as environmental and natural resources. So, to avoid the effect to use industrial waste productions as a supplementary cementitious material (SCM) in making concrete i.e. silica fumes, rice husk ash, fly ash, metakaolin, alccofine, ground …

Performance of Polymer Modified Polypropylene Fiber Reinforced Concrete
Abstract: AbstractThe fiber reinforced concrete (FRC) is a composite material essentially consisting of conventional concrete reinforced by random dispersal of short, discontinuous and discrete fibers of specific geometry. The conventional plain concrete possesses high compressive strength, low tensile strength, poor impact strength, ductility, and little resistance to cracking and poor resistance to chemical attack. The presences of micro-cracks at the mortar aggregate interface are responsible for the inherent weakness of plain …
