The sand brick can also be made by using dolomite quarry waste as a sand replacement at 0%, 25%, 50%, 75%, and by the weight of sand content . The dolomite sand can produce autoclaved aerated concrete (AAC), which showed better performance than the normal autoclaved aerated concrete . The various literature studies revealed that the ...
2.5. Stone Quarrying in Ethiopia Ethiopia is the place on earth in which humanoids made the first stone tools, and the sophisticated use of stone in the construction of building dates much earlier 3.5 million years back. The country hosts some of the world's most impressive stone works from Antiquity and the Middle Ages in the world.

This research was conducted to examine the potential of basaltic crusher dust as a partial replacement for Portland Pozzolana cement in hollow concrete block (HCB) production. Quarry dust is one of the waste materials abundantly available and pozzolanic material in the quarry industry. In doing so, physical tests of cement pastes and hollow concrete blocks of …
The bedrock geology of Ethiopia exhibits a variety of rock types that can potentially be developed for building stone production. The ETHIONOR project has so far included investigation of such resources in the southern and central parts of Ethiopia. Within the Precambrian, there are several deposits of pink and grey granitoids, grey and white marble, soapstone and serpentinite; a …
Sand is used more than any other natural resources except water and air, However, it's extracted at a rate far greater than it's renewal. The availability of sand in the growing demand of the construction industry will be a challenge due to a wide range of variability, cost, and, quality problems. This study aims to investigate normal strength concrete by …
The price of cement, river sand and quarry dust were obtained from the local market as SLR 1095 per 50 kg bag, SLR 5925 per cubic meter and SLR 5330 per cubic meter, respectively.
