Handling of Aggregates in The Ethiopian Construction Industry:
Sandy Materials in Civil Engineering Usage and. The production of aggregate for the infrastructural development of the country has been increasing for the production in Ethiopia. Normal weight aggregate is generally produced in Ethiopia by crushing parent rocks using mechanical crushers or traditional methods. Basaltic rock is a good example of parent rock, which is used mainly for coarse aggregate production in and around [4]. 2.2.

Environmental Impact and Sustainability in Aggregate Production
Somewhat simplified, the activities of the aggregate industry can be compiled into four essential phases (Danielsen 2007 ): (1) Inventory and planning, (2) Quarrying and production, (3) Use of aggregates in construction, and (4) Reclamation of mined-out areas. Each of these phases will contain a number of sub-activities.The study also identifies in aggregate, the price of maize taking the average of prices in all the markets has increased by 46%.

Opportunities to boost sesame production in Ethiopia
Ethiopia has produced a total of 8,598,531 quintal of oil seeds in the 2017/18 two harvest seasons (Belg and Meher seasons) covering 879,551 hectares of land. The share of commercial farms meanwhile is small. Out of the total production 18 percent is produced by commercial farms, according to the Central Statistics Agency of Ethiopia The cost-effectiveness analysis of concrete mix design has been carried out by calculating the unit cost of concrete per cubic meter for each mix design method using the cost of concrete ingredients in Debre Markos City, Amhara Region, Ethiopia, with a current cost of cement of $8.67 per bag, the coarse aggregate of $20 per cubic meter, Comparative Analysis of Selected Concrete Mix Design Methods
