NOVELTY - Nuclear sacrificial concrete comprises 300-450 pts. wt. ordinary Portland cement, 120-150 pts. wt. ultra-fine fly ash, 20-40 pts. wt. silica ash, 900-1200 pts. wt. river sand, 0.5-3 pts. wt. polyvinyl alcohol fiber, 5-10 pts. wt. polycarboxylic acid water reducing agent, 180-200 pts. wt. water and 0.3-2 pts. wt. graphene oxide. USE - Used as nuclear sacrificial concrete. ADVANTAGE - The nuclear sacrificial concrete: can meet engineering requirements of fluidity, work performance and decomposition and transformation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing nuclear sacrificial concrete, comprising (i) mixing and stirring ordinary Portland cement, ultra-fine fly ash, silica ash, river sand, to obtain mixed cementitious material, (ii) adding polyvinyl alcohol fibers to above mixed cementing material, and stirring to obtain uniform material, (iii) adding mixed solution of water, polycarboxylic acid water reducing agent and graphene oxide to above homogeneous material to obtain uniformly mixed slurry, which is stirring slowly and then rapidly stirring, and (iv) standard molding and curing to obtain nuclear sacrificial concrete.
