RESUMO

The main goal of this project is comparing the performance of structural ceramic blocks with 11,5 (Block A) e 14 (Block B) centimeters thickness, through tests with blocks, prisms and small walls using two types of mortar, ii and iii, determined by the British Norm (BS-5628) developed in laboratory. The experimental program includes simple axial units compression tests, prisms of three overlapping rows and wallettes of two blocks by four height rows. During the prisms and wallettes tests, their strains were measure, and subsequently the elasticity modulus was obtained. From the results, it was concluded that the 11,5 centimeters thickness block (Block A) presented the capacity to absorve the strain of equal value as the tradicional block, and may be used with safety. Analyzing the results of the tests it was possible to verify different values near to the compression strength value in the test specimens using the two types of blocks, establishing difference between prisms and wallettes, with the same type of mortar. It was carried out the statistical analysis to check the difference between the blocks, where it was observed the equality between the blocks with average compression strength and the prisms with two types of mortar, however in the wallettes tests it was observed difference between the average strength with the two types of blocks.
