【摘要】 <正> 镁水泥浆体的碱度要比普通硅酸盐水泥低得多,它属于较弱碱性的介质,根据作者测定其pH为8.5～9.5。但是在工作中我们发现: (1) 玻纤增强的镁水泥试样的抗冲击强度起初很高,但随其存放而较快下降; (2) 经过较高温度的镁水泥滤液(如60℃/14d)浸泡后,玻纤强度下降。更多还原

【Abstract】 The distribution of Na, K, Ca, Si and Al on the surface of glasa fibre immersed in magnesia cement filtrate was measured by AES spectrum. The mechanism of the corrosion of the glass fibre by magnesia cement was discussed.更多还原
