Influence of sintering temperature of a ceramic substrate in mortar adhesion for civil construction

The mortars have a fundamental role in the buildings, as in the placement of blocks or in use as a wall and ceiling coating, another application and the fixing of ceramic tiles for coating. The variation of the properties of the ceramic substrates directly influences the efficiency of the coating system of the constructions. The objective of this work is to analyze the influence of the firing temperature of the ceramic blocks, known as substrates, on the adhesion property of the mortar based on cement and lime, for this purpose, were made ceramic blocks in different firing temperature (750 °C, 850 °C and 950 °C) and physical, chemical and mineralogical characterization of the clay used without processing. The results indicated that the firing temperature is a variable that directly influences the properties of the red ceramic where the bricks burned at 950 °C provided greater gain of resistance to the adhesion of traction due to the high initial absorption index compared with the temperatures of 850 °C and 750 °C.
