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 …

Effect of Compressibility on Undrained Bearing Pressure of Circular Footing Resting on Two-Layered Clay
Abstract: The present study aims to investigate the behavior of a circular foundation on layered clay of varying properties. There are several solutions for the bearing capacity of footings on two-layered clays, but none of them considered the compressibility of the strata. An underestimation of the soil bearing capacity is the main cause of failures. The typical difficulty in estimating the capacity of soil is its complicated behavior attributed to the …
