Study on Properties of Polymer Mortar with Foundry Sand

Concrete is an irreplaceable construction material worldwide. Due to many external factors, concrete structures deteriorate. Every concrete structure is liable to deterioration and needs maintenance and service by repairing the cracks and distress to maintain the service life of the structure. Polymer mortar is one such material which is used as a repair material. Urbanization has led to increased use of construction material like river sand and accumulation of industrial waste. The adverse change of too much removal of sand from river beds is a threat to ecosystem and lack of land for disposing foundry sand which is a waste from casting industries has forced to search for another possible solution. Recovery and re-use of foundry sand as an alternate source to river sand contributes to reducing the demand for sand and also provides an environmentally sound method for foundry sand disposal. In this paper, we will be using polymer mortar as control mix without changing the water to cement ratio (w/c) and partially replace foundry sand in different proportions. This paper deals with study of the properties of polymer mortar with foundry sand as an alternate source to river sand by performing a series of strength tests with different proportions of foundry sand.
