The concrete blocks produced conventionally and using 50% of tailing were in the same absorption range. In comparison, the blocks manufactured with the highest amount of waste (70%) showed the highest value for absorption. Based on these results, the use of 70% tailings in the production of blocks presents the least favorable results.Web
