A study was conducted to establish the suitability of using all-in-aggregates as an alternative to conventional stones and sand for concrete production in order to reduce the cost of producing concrete for low cost housing without compromising on quality and strength.
The physical and mechanical properties of all-in-aggregates obtained from ten different sites in three regions of Ghana and used for concrete production were therefore determined by carrying out various tests including sieve analysis, Atterbergs limit tests and slump test. In addition the compressive strengths of concrete cubes made from the all-in-aggregates were determined at 7, 14, 21 and 28days.
It was found that strengths obtained were comparable to concrete made from conventional sand and stones under similar conditions. It was therefore suggested that to further reduce the cost of low cost housing all-in aggregates with comparable properties could be used as substitute for conventional stones and sand in concrete production.
