Influence of Microstructure on The Resistance to Salt Crystallisation Damage in Brick
Abstract In the article we study the variation of brick durability and, more specifically, its resistance to salt crystallisation produced by changes in its microstructure during firing. For this purpose, the evolution of both mechanical and pore structure properties are studied within a wide range of temperatures (700–1100∘C). An increase in the firing temperature produces a more homogeneous and resistant brick, measured using ultrasound velocity and uniaxial compressive strength. This result is obtained thanks to the vitrification process and changes in the brick's pore structure: larger, rounder pores, which are quantified by their roundness and fractal dimension. As a result of these changes, an excellent durability is achieved in the bricks studied when fired at temperatures above 1000∘C. Considering that few differences are noted in pore structure and brick strength between 1000 and 1100∘C, the recommended firing temperature is, for raw materials with a similar composition and production process, 1000∘C, as this involves a lower production cost than firing at 1100∘C.
