摘要
采用不同种类、形态和数量的石膏及含铝原料 ,配制出不同膨胀率的钙矾石型膨胀剂 ,研究不同膨胀剂对水泥性能的影响规律 ,分析膨胀剂组成与性能之间的关系 ,提出应按混凝土性能要求来设计膨胀剂。
The ettringite type expansion agent with different expansion coefficient is prepared by using different variety, pattern and quantity of gypsum containing aluminium raw materials. The influence regularity of different expansion agent on cement property is studied. The relation between composition and performance of the expansion agent is analyzed and the expansion agent should be designed as per concrete property requirements.
