Avaliação da resistência à compressão e absorção de água em tijolos solo-cimento com incorporação de vidro moído

Abstract

The different waste generated by human activities cause problems of increasing proportions. Need so more areas intended for their deposit, making the cost increase over the years, mainly due to the shortage of sites for landfill and increasing distances to be travelled to the final destination of the waste or tailings. In the present work had as objective to verify the technical feasibility of the incorporation of urban solid waste, glass, manufacture of ecological bricks. Were shaped bricks in the proportions of 0, 2.5, 5 and 7.5% in relation the amount of cement to particle diameters less than 75 µm and in the proportions of 0, 2.5, 5 and 7.5% of glass in relation to total mass (cement + ground). The bricks after cast went through wet cure and were tested to simple compression to 07 and 28 days old. The results showed that none of the molded bricks hit the minimum strength laid down in standard. The water absorption test was performed at 28 days of age the bricks. In relation to water absorption was found all the bricks presented values above the maximum recommended value.
