The masonry has been widely used in various regions of Brazil, showing itself as a growing market for this type of construction technique. This research studies the compressive strength of concrete block prisms seated with chemical mortar type A and B and conventional mortar industrialized, aiming to analyze comparatively the results. The use of chemical mortar derives from the construction site stockpiles of sand, cement and lime, with no need to add any component, because the product already has a satisfactory workability, in addition to be already prepared for a determined resistance so the constructor just need to make an analysis about the costs. The concrete blocks used in the tests did not pass by the drying step, since the intention was to perform tests on blocks in real conditions of work, a factor which had great influence on adherence and conferred it a low initial resistance to chemical mortars. This research also made studies about paver mortar type A and type B, however the results were disconsidered, for they were executed with different thicknesses and different contact areas, making the analysis difficult because the values were quite different. Finally an analysis was made at the time of the prism breaking to analyze where the rupture began. |
