Mechanical behavior analysis of small-scale modeling of ceramic block masonry structures: geometries effect

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.
