NOVELTY - Mortar comprises 50-60 pts. wt. cement, 30-50 pts. wt. shale ash, 10-20 pts. wt. boron slag, 30-50 pts. wt. water, 3-5 pts. wt. porous magnesium oxide fiber, 0.5-1.5 pts. wt. sodium laurate polyoxyethylene ether sulfate, 1-3 pts. wt. allyl-2-acetamido-2-deoxy-beta-D-glucopyranoside/glyphosic acid C/tributylvinyltin/vinyltrimethoxysilane copolymer, 3-8 pts. wt. graphene oxide fiber-doped metal ion, and 1-3 pts. wt. carbon nanotube fibers. USE - Used as the mortar containing cement. ADVANTAGE - The mortar: has electromagnetic shielding function, wide electromagnetic shielding band, high toughness, crack resistance, good impermeability, high corrosion resistance, and has high compressive strength; and can meet the requirements of different building materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the mortar comprising mixing cement, shale ash, boron slag, porous magnesium oxide fiber, sodium laurate polyoxyethylene ether sulfate, allyl-2-acetamido-2-deoxy-beta-D-glucopyranoside/glyphosic acid C/tributylvinyltin/vinyltrimethoxysilane copolymer, graphene oxide fiber-doped metal ion, and carbon nanotube fiber, then adding water, stirring at 60-80 degrees C for 3-5 hours, and cooling to room temperature.
