Análise experimental da influência da resistência e espessura da argamassa de assentamento no desempenho mecânico de prismas de blocos cerâmicos

Abstract

The use of the structural masonry can help to reduce the habitational deficit in Brazil, for being a constructive economic and rational system. It is formed by the junction of blocks united with an establishment mortar. This work has as purpose to analyze experimentally, through a factorial planning 32, the influence of the compressive strength and of the thickness of the bedding mortar in the mechanical acting of no grouted prisms of structural clay blocks, one of the methods adopted by the Brazilian standard for analysis of the masonry. For this, it was studied blocks of same compressive strength, making prisms of two blocks with variable thickness of 10 mm, 15 mm and 20 mm and equivalent resistances to 50%, 100% and 150% of the strength of the block in the gross area. With the results of the tests, it was gotten to build representative models of the effects individual and united of the variables thickness and compressive strength of the mortar.
