Therefore, selection of optimal quarry sites for crushed aggregates is a prerequisite for safe operation and economic viability. The present study was carried out around Harer and Dire-Dawa towns located about 520 km from Addis Ababa.
also concluded coarse aggregate producers produce less than 50% of the minimum recommended production capacity of crushers. Improving efficiency and product quality in the coarse aggregate industry in and around Bahir Dar could be addressed: In the short term, appropriate
A detailed study was conducted by Tesfaye A. and Giulio B. on Termaber basalt, a widely used basalt in the central highland of Ethiopia and that comprise the major source of local crushed rock aggregates and building stone.
Construction aggregate is crushed rock material used in concrete which make up most of engineering works. The main objective of this research was to assess the quality of coarse aggregates and evaluate their suitability for concrete of the limestone rock material sources in Mekelle area, northern Ethiopia.
One crucial material is aggregate, which is a broad term that encompasses crushed stone, gravel, sand, and recycled concrete. Aggregate is used in the manufacturing of concrete and asphalt, making it a vital component in the construction industry.
Construction aggregate is the sized, or crushed and sized, rock material used in concrete and asphalt, which make up most of highways, bridges, houses and other engineering works. Aggregates range in size from large boulders (rip rap) used as fill in large construction projects to finely-grained
Three aggregate types, crushed limestone, crushed dolomite, and uncrushed gravel, were tested in the laboratory for resilient modulus (M-R) and permanent deformation characteristics at...
The study presented in this paper was carried out on basalts that are widespread in the central highland of Ethiopia and that comprise the major source of local crushed rock aggregates and building stone.
Geo-engineering evaluation of Termaber basalt rock mass for crushed stone aggregate and building stone from Central Ethiopia. Tesfaye Asresahagne Engidasew, G. Barbieri. Published 1 November 2014.
Natural aggregates are obtained from quarries by processing crushed rocks or from riverbeds while artificial aggregates are obtained from industrial by products such as blast furnace slag.
