Effect of Partial Replacement of Cement by Quarry Dust, Rice Husk Ash with using Polyester Fiber in Concrete

Abstract

Generally Portland cement is used as binding material in concrete which liberates large amount of co2 while manufacturing. Hence there is an urgent need for proper attention and to minimize their impact on the sustainability of our living environment. In this study quarry dust and Rice husk ash were partially replaced for cement material, And adding the polyester fiber to strengthening the rebar. In this investigation marble dust and rice husk ash are used as a replacement for cement in various proportions such as 0%, 10%, 15%, 20%, 30% in a total replacement of 30% of cement, Where in each proportion the remaining percentage is filled by the Rice husk ash. Marble dust contains more than 50% of silica content in it. Study of Index property and engineering property were obtained in laboratory. Cube casted along the polyester fiber with aspect ratio 100 is adding as reinforcement agent. Polyester had added as 0.1% .
