摘　　要：以工业无碱速凝剂配方为基础,通过对其组分进行优化,使其性能得到改善。优化后结果表明,当速凝剂B掺量为7%时,可以使P.O 52.5硅酸盐水泥的初凝时间为2.43min,终凝时间为5.88min,1d的抗压强度为12.4MPa,28d的抗压强度比为94.84%。The improvement of the performance of the industrial formulations on an alkali-free liquid acceterating agent with cement was researched by the design and regulation of its chemical composition. The results show that the initial setting time and final setting time of the Portland cement added with 7 % low-alkali liquid accelerating agent is 2. 43 rain and 5. 88 min,and its 1 d compressive strength reaches 12. 4 MPa,28 d compressive strength ratio is 94. 84%
