The setting process of CA mortar was governed by several factors such as the cement types,asphalt emulsion/cement ratio(m(A)/m(C)).
研究了水泥组成、沥青乳液与水泥的质量比等因素对掺沥青乳液水泥净浆的凝结时间及CA砂浆的材料分离度、流动度、可工作时间、抗压强度等性能的影响规律。
Effect of mixing sequence of asphalt emulsion on strength development of CA mortar was studied by calorimetry and electrical resistivity measurements.
采用水化热-时间曲线和电阻率-时间曲线研究沥青乳液加料顺序引起CA砂浆早期强度不同的原因,研究结果表明,先加沥青乳液对水泥具有较强的缓凝作用,而后加沥青乳液的缓凝作用较弱,这是导致后加沥青乳液能显著提高CA砂浆早期强度的根本原因。
The paper explored the variation in compressive strength of CA mortar under different loading rate,and also investigated the effect of ratio between asphalt emulsion and cement,the fineness modulus (FM) of sand,and the incorporation of silica fume (SF) and crumb rubber (CR) on the time rela.
首先研究了CA砂浆抗压强度在不同加载速率下的变化规律及沥青乳液与水泥的相对质量比、砂的细度模数与外掺料硅灰(SF)和橡胶粉(CR)对CA砂浆抗压强度时间依赖性的影响。
Described hereby are the classification and functions of bitumen emulsion for road works with reference of large amounts of information.
参考大量文献资料综合叙述了道路用沥青乳液的分类和作用,重点讨论了沥青乳化剂的选择和沥青乳液稳定性的影响因素,并进一步探讨了今后的发展方向。
