Experimental Investigation on Waste foundry sand with Recron fibre in Reinforced Cement concrete

Civil engineering

The consumption of natural resources in construction has increased from decades, which is the result of high cost. , construction industries have already identified alternatives like manufactured sand, robo sand, rock dust etc. Another alternative to this can be use of waste material in concrete to overcome the use of natural resources use of waste material like foundry sand in concrete could be make possible to achieve the low cost construction. This paper is based on the Experimental investigation on waste foundry sand with recron fibre in Reinforced Cement Concrete. The detail study about the waste foundry sand is a waste material obtained from ferrous and non-ferrous metal casting industries. and properties of the materials are determined by various tests and the mix proportion standard specimens will be casted and cured for 28 days to get the compressive strength, flexural strength and split tensile strength. In this process Recron fibre is comonomer special for( improved holding of cement aggregates ,Tensile strength :4000-6000 kg/cm2, Melting point > 250oC) also fibres are uniformly dispersed which has better properties to resist internal stress due to shrinkage. Also reduces segregation and bleeding Then the final result is evaluated by comparing the above strengths of reinforced concrete filled with waste foundry sand and Recron fibre .
