Abstract

the continuous use of sand from river beds leds to an environmental problem. The production of cement leads to the emission of a vast amount of greenhouse gases, forcing researchers to look for an alternative. The possibility of use of quarry dust and pond ash as a suitable replacement of fine aggregate and cement in concrete respectively is explored in this study. It has been estimated that 20% of rock comes out as dust during crushing from quarry site. In the thermal power station the ash which is fall at the bottom of boiler is mixed with water and then it is carried away from plant through pipes and finally dumped on open land. After evaporation whatever ash remains is called pond ash. The need to develop concrete with non-conventional aggregates is urgent for environmental as well as economic reasons. Here fine aggregate is partially replaced with quarry dust by 20%, 35%, and 50%. Along with that the cement is also partially substituted with Pond ash by 5% and 10%.Hence, there are seven batch mixes including conventional one. In this study the following tests will be done: (1) Compression test (2) Split tensile test (3) Flexural test.
