An experimental investigation on the buried internal explosion in finite thickness concrete targets was carried out, with the aim at developing an available criterion for the critical collapse of rear-surface to determine the critical collapse thicknes... see more

This paper presents a dimensionless model for the depth of penetration (DOP) of a projectile penetrating into a concrete target, based on the similarity theory involving intermediate asymptotics, complete similarity, and incomplete similarity. The calcula... see more

In this paper, we attempted to make an investigation to use E-waste as fractional substitution intended for coarse aggregate. The accumulation of electronic waste is a major concern in big metropolitan cities and certain tier 2 cities in which huge quanti... see more

Due to the high aggressiveness in which the concrete structures are exposed, many researches have been developed in this area and search for materials with superior mechanical performance and durability has been the target of the researchers of concrete t... see more

A new spiral warhead structure which makes concrete failure by self-rotation is proposed in this paper. Concrete dynamic response when subjected to the oval and new proposed spiral projectile vertical and oblique-angle (from 60° to 70°) impacts of differe... see more

The damage of concrete subjected to explosion loading is an important issue in defense engineering. The damage degree of concrete is related to many factors, such as the type of explosive charge, the depth of burial and the parameters of concrete. In this... see more

This research project evaluated the effect of using recycled aggregate and ground granulated slag on pervious concrete specimens compacted using two different methods: fixed energy and fixed porosity. The permeability, compressive strength, and solar refl... see more

A Haitian general contractor/civil engineer was having difficulties achieving the target concrete strength even when the mix was designed in compliance with the regulations and client criteria. An experiment was carried out to assess the quality and perfo... see more

This paper presents the results of an experimental evaluation between predicted and practice concrete strength. The scope of the evaluation is the optimisation of the cement content for different concrete grades as a result of bringing the target mean val... see more
