Abstract
This paper presents the experimental results of a research program with ceramic block masonry under compression. Four different block geometries were investigated. Two of them had circular hollows with different net area. The third one had two rectangular hollow and the last block was with rectangular hollows and a double central webs. The prisms and walls were built with two mortar type 1:1:6 (I) and 1:0,5:4 (II) (proportions by volume of cement: lime: sand). One:three small scale blocks were used to test block, prisms and walls on compression. It was possible to conclude that the block with double central webs gave better results of compressive strength showing to be more efficient. The mortar didn't influenced the compressive strength of prisms and walls.

This paper presents the experimental results of a research program with ceramic block masonry under compression
The increasing use of ceramic block masonry structures as construction systems in the Brazilian building market has been a factor in generating research projects focusing on development of masonry products that maintain a high efficiency capacity when subjected to external loads
Summary
In the state of Santa Catarina, there are 742 pottery facilities with a production of approximately 100 million units per month that are responsible for 11,000 direct jobs and 30,000 indirect jobs. This industry is socioeconomically very important [1]. The pottery sector has approximately the same profile in almost all Brazilian states, showing both a high production potential and the small-scale technological and investment capacity for creating new products. The main goal of this work is experimentally analysing and assessing the influence of ceramic block geometry on the mechanical performance of structural walls under compression on a small-scale, allowing such blocks to potentially become an important component for the Brazilian ceramic industry
