بررسی تجربی خواص رطوبتی مصالح ساختمانی تاریخی با استفاده از روش هیدروفوبیزاسیون

In this paper moisture properties of the building bricks from a historic building before and after the hydrophobization treatment were experimentally investigated. The building bricks were impregnated in the water repellent agents with different concentrations of the active ingredients. Water absorption test and water vapor diffusion test were conducted to observe the influence of the hydrophobization on the moisture transport behaviors of the brick. The results are beneficial for the researchers to find the optimal solution to improve the hygrothermal performance of the building facades.
