摘要
碳酸化养护水泥主要矿物及熟料,研究其碳酸化过程中的矿物变化、机理和效果。结果表明:C3S、C2S、C3A和C4AF 4种水泥矿物在一定条件下均可发生碳酸化反应,矿物碳酸化自发进行的难易程度顺序为C3S(C2S(C4AF(C3A,其中1 g的C3S和1 g的C2S可分别固化储存CO2气体0.168 g和0.125 g;1 g水泥熟料可固化储存CO2气体0.146 g。碳酸化养护的水泥熟料试样2 h强度达24.65 MPa,3 d强度达41.65 MPa。
Carbonated curing of main cement minerals and clinker,the change of minerals after carbonation,and the effect and mechanism of carbonation were studied.The experimental results show that carbonation reaction can occur in four cement minerals（C3S,C2S,C3A,and C4AF） under certain conditions,and the difficult or easy degree of spontaneous carbonation is C3S﹥C2S﹥C4AF﹥C3A;1 g of C3S,C2S and clinker can sequestrate 0.168 g,0.125 g and 0.146 g CO2 gas,respectively.After carbonated curing,2 h strength of clinker samples is 24.65 MPa and 3 d strength is 41.65 MPa.
