Abstract Scope |
In the casting process it is common to use green sand, as it is a simple and cheap molding technique that leads to the generation of a significant amount of waste after demolding the manufactured part. The objective of this work is to use this residue for the production of interlocking concrete block paving (paver), using the percentages of 5, 15 and 25% of the residue in the mixture in substitution. The compressive strength and water absorption were analyzed, according to the Brazilian standard NBR 9781/2013, comparing the results considering paver with and without the use of green sand residue. The results achieved for paver with 5% of residue proved to be more efficient, although the others also presented acceptable behavior, being this new product an alternative to mitigate the environmental liability of this residue, being able to reduce the final cost of the product and the consumption of feedstock. |
