Effect of Mechanical Properties with Addition of Vigna Mungo And Bamboo Leaf Ash in Recycled Green Sand Moulding

摘要

The quality of cast products in Recycled Green Sand (RGS) moulds is mainly influenced by the mould properties, such as green compression strength, permeability etc. RGS was made by mixing with different percentages of additives such as Vigna Mungo (VM) and Bamboo Leaf Ash (BLA) to RGS. Consequently, cylindrical specimens of RGS were prepared based on standard procedures. In order to study the effect of VM and BLA additives to RGS, the prepared RGS specimens were subjected to basic sand testing including permeability, green compression strength using standard methods and equipment. In the present investigation, experiments have been carried out that the RGS specimens containing VM 0-1.0% of RGS by weight and BLA 0.5-2.5% of RGS by weight were exhibit attainable green compression strength and permeability. It also obtained experimental results and were proved that RGS specimens revealed relatively enhanced properties as compared to green sand specimens contained without any additives.
