NOVELTY - Electromagnetic shielding sand-cement concrete comprises 10-15 pts. wt. cement, 0.5-2.5 pts. wt. conductive fiber, 0.5-2 pts. wt. graphene, 1-3 pts. wt. zeolite, 2-5 pts. wt. fly ash, 22-29 pts. wt. machine-made sand, 45-55 pts. wt. aggregate and 3.8-6 pts. wt. water. USE - Used as electromagnetic shielding sand-cement concrete. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing electromagnetic shielding sand-cement concrete comprising (i) placing graphene in water, using ultrasonic disperser at frequency dispersion of 60 Hz for 11-15 minutes, (ii) taking cement, zeolite, fly ash, machine-made sand and aggregate, placing in a concrete mixer for 2-5 minutes, (iii) mixing treated material in step (i) into mixer of step (ii) for 8-12 minutes, and (iv) adding conductive fiber into step (iii) in a stirred machine for 1-2.5 minutes to obtain final product.
