The purpose of this study was to investigate the change in the physical and mechanical properties of styrene-butadiene copolymer (SB) dispersion-modified calcium sulfoaluminate (CSA) cement mortar as it aged from 28 to 360 d, and cured at different temperatures and relative humidities. The results show that the mechanical properties of reference mortar (RM) of CSA cement, including its flexural, compressive, and tensile bond strength, showed a reduction after a certain time, but its water capillary absorption was hardly affected by age. When SB dispersion was added, there was no reduction in mechanical strength. The amount of SB added did matter. Addition of 5% SB had a negative effect on most properties compared with RM, except for tensile bond strength. However, the properties of SB-modified mortar (SBMM) were enhanced significantly as the amount of SB was increased from 5% to 20%. Temperature change had different effects on the properties of RM and SBMM. High temperature was beneficial to early flexural and compressive strength development of RM, but caused serious strength reduction at later stages. High temperature enhanced the development of tensile bond strength of RM. Increasing temperature enhanced properties of SBMM, including flexural, compressive, and tensile bond strength. Higher relative humidity improved all measured properties of all mortars. Scanning electron microscope (SEM) observations of the morphology of RM and SBMM at 360 d cured under different conditions accounted well for the changes in mechanical properties.


创新点:1. 发现丁苯共聚物可以抑制硫铝酸盐水泥砂浆后期强度倒缩;2. 理清了温度和湿度对对比砂浆和改性砂浆性能的影响规律.
结论:1. 从28天到360天,对比砂浆力学性能(包括抗折强度、抗压强度和拉伸粘结强度)先随龄期的延长而增长,但到一定龄期后会出现倒缩,而毛细孔吸水率几乎不受龄期影响.2. 丁苯共聚物的加入可以有效抑制硫铝酸盐水泥砂浆强度倒缩、降低毛细孔吸水率,而且当丁苯共聚物掺量达到10%及以上时砂浆性能得到显著改善.3. 温度对对比砂浆和改性砂浆的影响规律不同;高温有利于砂浆早期强度的发展,但也会引起对比砂浆后期更严重的抗折和抗压强度倒缩.4. 高湿有利于砂浆性能的发展.5. 扫描电子显微分析的结果很好地解释了物理力学性能的变化.
