A Study of Microproperties of Historical Brick Material and Qualitative Correlation between Strength and Pore Distribution

Abstract

Experimental materials in this paper are taken from songyue temple and fawang temple which are both in henan province, X ray fluorescence analysis method is adopted to analysis the chemical ingredients of the historical bricks come from two temples respectively; strength of the bricks come from two temples are compared also; then a model of porous bodies connected parallel is established to reflect the pore distribution of material, the qualitative relationship between strength of material and porosity/pore distribution is derived; mercury intrusion method is used at last to get the porosity and pore microproperties of the historical bricks come from two temples, results show that porosity and microproperties of pores are important factors that affect the characteristics of historical brick material.
