Title: Additive for mortar or concrete
Inventor: AKASHI MITSURU
IPC: C08L101/00

Abstract: PURPOSE: To improve mechanical strength and reduce cracking, etc., of mortar or concrete by adding a heat-sensitive highly water-absorbing polymer to mortar or concrete to effect the absorption of water in kneading and the release of water in setting. CONSTITUTION: A heat-sensitive highly water-absorbing polymer composed mainly of a polymer or its derivative containing e.g. an N-vinylacylamide as the monomer component is added to a mortar or concrete material in an amount of 0.1-10 pts.wt. based on 100 pts.wt. of the mortar, etc. The polymer is not highly susceptible to the humidity of the environment, absorbs a large amount of water in the polymer at a low temperature such as in the case of kneading cement and releases the absorbed water at a high temperature caused by the heat of hydration e.g. in the setting of placed cement. For further improving the water-content controlling function, it is preferable to use a heating and cooling means to keep the cement to a relatively low temperature in kneading and to a relatively high temperature in setting.
