5%, and about 25% other gel voids, capillary pores, voids, etc. In particular, calcium hydroxide is precipitated in the capillary portion. These pores and voids, as well as cracks and cracks formed due to internal or external stress, and voids and pores caused by various other factors, allow water, air, carbon dioxide, etc. containing reactive substances to enter. Calcium hydroxide precipitated in the pores and unstable concrete components react with these intruding substances and cause the concrete to deteriorate. However, regardless of the surface and shallow parts, once formed in the deep part of concrete,
Techniques for filling and repairing voids, cracks, etc. have not been known in the past, and it has not been possible to extend the limited lifespan of concrete structures.

Coated or sprayed on the end face (see Figure 3), air-dried for 2 days, watered for 3 times a day for 10 days, air-dried for another 10 days, and compared compressive strength with 5 pieces without coating. I conducted a test. Table 4 shows each average value and the increase rate with respect to the case without coating, and a remarkable effect can be seen in those coated with #1.31.7 and #8. As a reference value, the apparent specific gravity is the maximum i! %llf! #8
An average increase of 2.16% was observed.

するものである。Effects of the Invention As explained above, the crystal growth agent for concrete and mortar of the present invention can be applied to or sprayed onto the surface of concrete or mortar, or filled into cracks, thereby reducing pores, voids, or cracks. Since crystals form deep inside the concrete and become dense, concrete and mortar can be prevented from deterioration, strengthened, and water-tightened with extremely simple operations. It has the revolutionary effect of being able to extend Nowaki.
