Effect of Local Coarse Aggregate Type on Concrete Mechanical Properties in Bangladesh

Different types of natural coarse aggregate are available in the local market Bangladesh, which primarily imported from several regions neighboring country, India. This paper aims to find best locally for concrete preparation terms mechanical strength. It also reports on results an experiment investigation that looked at effects six different aggregate, namely Burimari, Bhurungamari, Bholaganj, Tamabil, Jaflong and Dinajpur Hili (Indian Black Stone), Bangladesh properties concrete. Concrete cylindrical specimens 100mm diameter were prepared by each type keeping other ingredients constant. mix ratio water/cement adopted study 1:1.5:3 0.48, respectively. The Compressive strength, splitting tensile strength modulus elasticity investigated 7, 14 28 days curing age. obtained showed Stone) is most suitable concreting having distinguished variation compressive compared aggregates used research.
