Abstract
Concrete is the main material used in the construction industry not only for the ability to produce infinite variety of shapes for precast forms and for its characteristics of high resistance to compression, but primarily for their low manufacturing cost. Nonetheless, the production [...]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
Nowadays, metallic fibre reinforced cementitious composites are widely used on many different construction elements: concrete beds, slabs, precast concrete industry, etc. Fibres reduce the crack generation due to the cementitious composite shrinkage and improves its flexural strength, [...]
Abstract
Autogenous self-healing of cement-based materials is a topic of current interest. This research evaluates autogenous self-healing in four types of mortars based on Portland Cement, one containing CEM II and the other 3 formulated with CEM I and different additions: fly-ashes; nanosilica [...]Abstract
Cement being the main constituent of concrete plays a vital role in concrete production. In Ethiopia, cement consumption has grown well with a growth rate of about 16.1% per year. Hence, an alternative material to partially replace cement was initiated to reflect the needs of the [...]
