近日，武汉市现代工业技术研究所研制出一种用在水泥砂浆中的防渗抗裂剂。该剂采用无毒聚合物制成，对环境无任何污染，用它配成的水泥砂浆与普通砂浆相比，可提高粘结强度和改变水泥热胀冷绩所造成的渗水。该防渗抗裂剂可根据不同用途，以不同的掺量加入混凝土中，搅拌均匀后 Recently, Wuhan Institute of Modern Industrial Technology developed a seepage-proof crack agent used in cement mortar. The agent is made of non-toxic polymer, and has no pollution to the environment. Compared with ordinary mortar, the cement mortar formulated with the agent can improve the bonding strength and change the seepage caused by the thermal expansion and cooling performance of the cement. The anti-seepage crack agent can be used according to different purposes, with different content added to the concrete, stir
