摘要
本研究探究了水泥总量、珊瑚砂率、减水剂掺量对C30强度等级的碱式硫酸镁水泥珊瑚混凝土(BMSC-CAC)立方体抗压强度(f_(cu))的影响。研究结果表明:BMSC-CAC的f_(cu)值与水泥总量、萘系减水剂掺量和珊瑚砂率有关,水泥总量的影响最大,f_(cu)的变化幅度达到14.4%,当水泥总量为600kg/m^(3)、萘系减水剂掺量为3%、珊瑚砂率为40%时,其f_(cu)值能够达到35MPa。
In order to investigate the influence of different naphthalene series water-reducing agent content,cement content and coral sand rate on cube compressive strength(f_(cu))of basic magnesium sulfate cement coral aggregate concrete(BMSC-CAC),the C30 strength grade concrete as the research object,the experiment was carried out.The results show that the f_(cu) of BMSC-CAC increases firstly and then decreases with the increase of cement content,naphthalene series water-reducing agent content and coral sand rate.When the cement content is 600 kg/m^(3),the naphthalene series water-reducing agent content is 3%and the coral sand rate is 40%,the f_(cu) reaches the maximum value of 35 MPa.
