Experimental study on mechanical properties of mortar materials under acidic environment

摘要

This paper, by means of the accelerated test under acidic environment, studies the physical chemistry and mechanical properties of the mortar materials in the different periods, analyzes the change regularity of hydrogen and calcium ions concentrations in acid solution in different periods and the mechanism of mortar subjected to hydrochloric acid corrosion, reveals the phased characteristic in corrosion process, puts forward the generalized model of the change of sample porosity considered corrosion process, and deduces the formula of flexural strength changed with time, preliminarily verifies the good consistency between calculation and experimental results.
