    Experimental Study on Physicochemical and Mechanical Properties of Mortar Subjected to Acid Corrosion by Runke Huo, Shuguang Li, Yu Ding

    Published 2018-01-01
    “…In the initial stage of corrosion, the chemical reaction increased the porosity of the specimen, which leads to the decrease of longitudinal wave velocity of the samples. At the same time, the corrosion solution continuously penetrates into the mortar pore system, which leads to the increase of the mass, and it is considered that the diffusion process plays a leading role during this period. …”
