Strength Properties of Concrete by Replacing Coarse Aggregate with Blast Furnace Slag and Fine Aggregate with Crusher Dust
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 11
Abstract
The demand of river sand in the construction industry has consequently increased due to Urbanization and mass construction of housing resulting in the reduction of natural sources and also an increase in price. In such a situation crusher dust or robo sand can be an economical alternative to the river sand. Hence crusher dust was used as replacement of fine aggregate with a dosage of 10%, 20%, 30%, 40% and 50%. In order to reduce the cost of concrete the usage of pozzolan in place of cement is also proposed to use. Blast Furnace Slag is a non-metallic product consisting essentially of Silicates and Alumino silicates of calcium's developed simultaneously with iron in a blast furnace and is granulated by quenching the molten material in water or steam, and air. The present Investigation has been undertaken to study the effect of blast furnace slag and crusher dust on the mechanical properties of concrete, when coarse aggregates is replaced by blast furnace slag and fine aggregate with crusher dust in different percentages i.e. 0%, 10%, 20%, 30%, 40% and 50%. The main parameters investigated were cube compressive strength, split tensile strength and flexural strength. The tests were conducted on concrete with ratio 1:1.86:3.77.
