Experimental Research on Isothermal Sorption of RAC Material


Article Preview

Material adsorption process is the reverse process of evaporation diffusion, reflecting directly the wetting degree of material, is one of the main factors of material drying shrinkage. Based on pore structure theory, this article designed a device measuring the wetting properties of materials, tested different recycled aggregate replacement rate recycled aggregate concrete isothermal absorption curve. The article proposes the water contact angle can be calculated from the initial absorption curve, and analyzes its impact on drying shrinkage of recycled aggregate concrete.
