properties of aggregate. The dominant rock for coarse aggregate production in Ethiopia is generally basalt while ignimbrite is most commonly used for masonry stone. On the other hand the majority of sand is collected from river beds (Abebe, 2005). In Mekelle area there are four lithologic rock units, dolerite, sandstone, limestone-marl-shale

Products are distributed throughout most of Ethiopia, even though a major part of the production is used in the capital. Fig. 13. Wall cladded with the Ambo sandstone, Hotel Sheraton, Addis Ababa. Basalt is widely used for local construction, both as building stone and aggregate, in those parts of the country where such rocks are found (Fig. 14).

of concrete is occupied by aggregate and 90% of asphalt pavement is aggregate [4, 5]. This increased the demand of aggregate in line with the sectoral devel-opment. Yasmin, in 2015 based on the annual cement production volume, estimated the demand of Ethiopian for sand would be approximately 1.5 million tons per year [6].

In Ethiopia, the practice of using alternative ingredients to produce materials was observed weak in some scenarios. It was because ignoring the right procedures to perform the required material requirements for construction materials. ...

Sand is a fine-grained material that is commonly used as a base for concrete and mortar, while aggregate is a larger and coarser material that is used for the structural support of concrete and asphalt. Understanding the differences between these materials is essential to ensure the success of any construction project.

Ethiopia is the 4th leading producer of pumice and scoria aggregate in the world following Italy, Chile, and Ecuador . Scoria is abundantly found especially in the main ethiopian rift valley (MER) and around Bahir Dar, however, it's used is limited to a base course in road construction and production of hollow concrete blocks [ 10 ].

Scoria is widely available around the central towns of Ethiopia, especially around the rift valley regions where huge construction activities are taking place. The aim of this paper is therefore to analyze …
