AN EXPERIMENTAL ATTEMPT ON PLAIN CEMENT CONCRETE USING MARBLE DUST AS A PARTIAL REPLACEMENT TO CEMENT AND ADDITION OF COCONUT FIBER BY WEIGHT OF CEMENT

Abstract

Demand for cement continues to grow, and also increase in the cost of conventional building materials; for this objective, the use
of industrial waste products and agricultural by products are very constructive. These industrial and agricultural by products
such as Fly Ash, Rice Husk Ash, Silica Fume, Marble Dust and Slag etc can be used as cementing materials because of their
pozzolanic behavior, and natural fibers like jute fiber, Coconut fiber can be used to increase the tensile strength of concrete,
which otherwise require large tracts of lands for dumping, thus the concrete industry offers an ideal method to integrate and
utilize a number of waste materials, which are easily available, and economically within the buying powers of an ordinary man.
Presence of such materials in cement concrete not only reduces the carbon dioxide emission, but also imparts significant
improvement in Tensile strength, and Compressive strength. The present study is carried out for evaluating the influence of
Marble Dust and Coconut fibers in M25 & M30 grade concrete. This study presents the results of workability, compression test
and split tensile test on concrete which were casted with various percentage of Coconut fibers ranging from0.75% to 1.25% at a
regular interval of .25% and Marble Dust ranging from 7.5% to 12.5% at regular interval of 2.5%
