Abstract :

During the manufacturing of paper products, waste is generated that requires proper reuse or recycling, among which is the sludge from its WWTPs composed mainly of cellulosic waste. The sludge consists of organic fibers, inorganic materials, and about 60% water. Daily production and the limited capacity of sanitary landfills cause social and environmental problems. An alternative for its management is to incinerate the sludge, which is used as part of the cement, light aggregates in the construction industry, soil improver, cement elaboration or other minority applications, but most of it is deposited in landfills. In this project bricks were manufactured, which are made with sludge from the paper industry, lime, cement and construction waste (all in one 1/4 "to fines). As for the mud that was used to make the bricks, it had to be dried, due to the high humidity they had, since this could generate problems of excess water in the specimens.Physicochemical and microbiological tests were carried out on the sludge of the paper industry in order to corroborate that there is no risk in their handling. Subsequently, a mix design was developed to know which mix is ideal for brick making. The elaborated specimens were subjected to compression and absorption tests according to the NMX-C-411-ONNCCE-2013 (Building Industry �?? Masonry �?? Blocks and Masonry units for non-structural use �?? Specifications and test methods). From these tests, it was obtained that the best mixture for making bricks should have the following percentages:
