After the concrete is hardened and dried, rainwater and underground water from the outside penetrate into the hardened body through the pores, so that the aqueous solution of hydraulic colloid or inorganic salts flows out, and then reacts with carbon dioxide in the air to form sulfur substances, which are attached to the surface of the hardened body after the water evaporates. This phenomenon is called Baihua, also known as "wall cancer".
