Basaltic rocks are widespread in the Central highland of Ethiopia (Pik et al., 1997). Basalts are in high demand now and likely to continue to be the preferred source for crushed rock aggregate in the future. The use of basalts as aggregate material and building stones is increasing from year to year in Ethiopia (USGS, 2010).

Aluminium and Zinc affect "Ecosystem Quality" by 45.6% and 17.7%. In particular, in the first case, the highest contribution can be attributed to 41.1% due to basalt sand, 26% due to basalt gravel and 23% due to Portland Cement production, while in the second, it is mostly due (for 92.4%) to the transportation linked to the raw materials ...

On the other hand, basaltic rocks in general have higher unit weight than other rocks and, therefore, basalt aggregate has high relative density, even though, they cause segregation and therefore difficulty in pumping of concrete (Fookes, 1980; Neville, 1995). Besides, basalt rocks also have potential from the point of view for alkali–silica ...
