Abstract

This paper presents the determination of an appropriate compressive–flexural strength model of palm kernel shell concrete (PKSC). The direct and indirect Ultrasonic Pulse Velocity (UPV) measurements, with respective to mechanical properties of compression (cube) and flexural (slab) [...]

Abstract

In recent years Venezuela has presented a crisis on the demand, commercialization and production of cement, the material needed for construction, therefor additive cements are being used without any type of regulations. This work presents the physical-mechanical characterization [...]

Abstract

Experiments on the development of compressive strength and static and dynamic Young’s moduli were performed by the following mix proportions of concrete: the first uses different types of Portland cement without fly ash (FA) with a water-cement ratio of 45%, keeping at different [...]

Abstract

This work present to the mathematical model in the form of ANN, intended for projecting concrete compressive strength. Input data was classified according to the type of component material and its content in concrete mix (cement contents, coarse aggregate, fine aggregate, water and [...]

Abstract

The local fired brick production technique is the known method of brick making, especially in Jimma Town. Firing of bricks in local brick production method is conducted by burning of much amount of woods. But this method of firing bricks by burning of woods will affect the environment. [...]

Abstract

Many years ago, consolidation accomplished by laborers wielding a variety of spades, tampers, and similar tools. In Ethiopia, there is no enough knowledge by the laborers, while the site engineers ignored the correct application due to some constraints. The agreement of acceptable [...]

Abstract

Cement is one of the components of concrete plays a great role in the construction industry. Nevertheless, it is the most expensive and environmentally unfriendly material. Therefore, requirements for economical and more environmentally-friendly cementing materials have extended [...]
