摘　　要：通过测定芦苇和水泥混合物的水化温度,研究芦苇和水泥的相适性,并采用对芦苇的预处理和添加添加剂等方法改善芦苇和水泥的相适性。结果表明,未经任何处理的芦苇和水泥的适应性较差;添加剂可以明显地改善水泥和芦苇的适应性,在几种添加剂中,以CaCl2效果较好;对芦苇预处理后,芦苇和水泥的适应性有不同程度的提高;当硅灰取代水泥用量的10%时,在一定程度上改善了芦苇和水泥的适应性。By measuring the hydration temperature of the reed and cement mixture,the compatibility of reed and cement are dealed with,and how to improve the compatibility of them by adopting pretreatment and adding additives to reed.There is low compatibility of untreated reed and cement.Additives can improve the compatibility,among the additives,CaCl2 has the best effect.It can improve the compatibility of reed and cement by treating the reed through physical or chemical methods.It can also improev the compatibility of reed and cement by adding silicon fume to replace 10% of cement significantly.
