NOVELTY - Water-proof mortar comprises 36-42 pts. wt. portland cement, 28-32 pts. wt. quartz sand, 18-22 pts. wt. latex powder, 16-20 pts. wt. mineral slag wool, 14-16 pts. wt. cellulose diacetate, 12-14 pts. wt. flexible fiber, 8-12 pts. wt. nano filler, 4-8 pts. wt. flexible resin composition, 1-3 pts. wt. graphene, and 2-5 pts. wt. rubber composition. USE - Used as water-proof mortar. ADVANTAGE - The water-proof mortar has good crack resistance; improves in crack resistance on the basis of maintaining the original performance, so that the material is not easily cracked or cracked. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the mortar, comprising (i) adding portland cement, quartz sand, latex powder, slag cotton, cellulose diacetate to a high-speed mixer, stirring at the rotation speed of 1050-1150 revolutions/minute (rpm) and stirring for 35-45 minutes to obtain the mixture A; (ii) adding cellulose diacetate to a high-speed mixer at a rotation speed of 1050-1150 rpm, and stirring for 35-45 minutes to prepare a mixture A; (iii) adding flexible resin composition, graphene, and adding rubber composition to the reaction vessel, and reacting at 95-105 degrees C for 25-35 minutes; and (iv) adding prepared mixture A, mixture B, flexible fiber and nano-filler into a high-speed mixer at a rotation speed of 1250-1350 rpm, and stirring for 1-2 hours.
