Suitability of Crusher-Dust as Masonry Construction Material
Abstract
Crusher dust generated at Kunduchi quarries in Dar es Salaam during aggregate crushing is counted as a waste material, and some times it .is disposed away or sold at a cheap price of not more than a quarter of that of sand. A study on the use of the crusher dust as a building material has been carried out in which samples were collected and analyzed for grading (sieve analysis). In additional to that, other samples were stabilized with a small amount of cement, from which bricks were produced and tested for compressive strength. Other bricks were bonded together using mortar which had the same ratio of cement to crusher dust as that which was used for manufacturing the bricks. Then both the bricks and the walls were tested for compressive strength. The results obtained from sieve analysis as well as compressive strengths have shown that the crusher dust masonry is a suitable building material which leads to lower cost of the walls if compared to concrete blocks.
