摘　　要：基于低热水泥吸热储能相变材料的作用原理,采用国标水泥水化热试验方法,分别对煤焦沥青、松香及石蜡3种相变材料进行了水化热和水泥石强度研究。研究表明,3种吸热储能相变材料中,松香与石蜡加入水泥浆中导致水泥石强度低于3.5 MPa,不能满足强度要求,而煤焦沥青水化的热温差为14.5℃左右,水泥石强度为4.8 MPa左右,符合低热水泥的标准,可以作为低热水泥外加剂。Based on the effect principle of endothermic energy - storage phase transition material for low thermal ce- ment, national standard test of hydration heat of cement is used in this paper. The authors study the cement hydra- tion heat and cement strength of coal tar pitch, rosin and paraffin respectively. Results have shown that the cement strength is lower than 3.5 MPa by the addition of rosin and paraffin , which cannot satisfy the strength requirements ; while hydration heat temperature difference is around 14.5℃ and cement strength is about 4.8 MPa by the addition of coal tar pitch, which can meet the standard of low thermal cement.
