Abstract

The Zoquite company is a vibrocompressed manufacturer located in the city of Guanajuato, in whose workshop pumice bricks with water-cement ratio of 1.0 and 1.2 were produced in a quasi-artisanal manner, which were cured in the curing chamber of University of Guanajuato. Likewise, representative samples of the raw materials were transported to the laboratory for analysis, finding that they complied with the specifications of the standards, except that the pumice has grains higher than 3/8”, which generated a porous texture in the brick that had influence in the failure path. In the pumice bricks that were characterized in accordance with the NMX and the ASTM standards, it was observed that the mixing water has a marked effect on the absorptions and contraction since its rationing is carried out considering the need of water for the accommodation by vibrocompression and not so much for hydration of Portland cement, a condition that resulted in a simple compression resistance that was reduced for the first days of curing, but at 28 days of curing it was higher than the standard limit of 3.43 MPa, an effect that is not as marked in the batch with the highest water content. Thus, the quality control of the pumice bricks manufactured by Zoquite, even when they are produced empirically and almost by hand, got the requirements established in the standards.
