The effects of borax, sodium gluconate and L(+)-tartaric acid on the hardening behavior and strength development of rapid-hardening calcium sulphoaluminate cement mixed with calcium chloride solution at -10 ℃ were investigated. The results show that the initial and final setting time of rapid-hardening calcium sulphoaluminate cement mixed with calcium chloride solution prolonge to 25 min and 28 min with 0.6% borax at -10 ℃, respectively. However, the setting time of pastes with sodium gluconate or L(+)-tartaric acid does not extremely change. The strength gradually decreases in the samples with increasing the dosages of borax and sodium gluconate at different ages. A maximum reduction of 25.5 MPa occurs in those samples. The strength of samples containing L(+)-tartaric acid sharply decreases. A reduction of 10.9 MPa in 3-day samples containing 0.3% tartaric acid and 27.3 MPa in 28-day samples containing 0.6% tartaric acid occur. The presence of 0.6% borax does not change the morphology of ettringite at 1 d, but decreases the amount of ettringite by 5.31%. A short column-like ettringite in the samples with sodium gluconate and a needle-shaped-like ettringite in the samples with L(+)-tartaric acid are detected, respectively. However, the amount of ettringite in those two samples above has no remarkable change. Borax is a suitable retarder for calcium sulphoaluminate cement at -10 ℃ because of the feasibility of setting prolongation and the acceptable strength reduction. Sodium gluconate and L(+)-tartaric acid have a slight effect on the setting time but change the ettringite morphology and deteriorate the strength.

研究了-10 ℃环境中氯化钙溶液拌合冷物料条件下，硼砂、葡萄糖酸钠、L（+）-酒石酸对快硬硫铝酸盐水泥凝结硬化行为、强度发展的影响，分析了缓凝剂对水化产物的影响。结果表明：-10 ℃条件下采用氯化钙溶液拌合时，0.6%掺量硼砂可使初凝时间延长至25 min、终凝时间延长至28 min，而葡萄糖酸钠和L（+）-酒石酸对初终凝时间影响不显著。随着硼砂、葡萄糖酸钠掺量的增加，不同龄期强度均逐渐下降，28 d最大降低值可达到25.5 MPa；L（+）-酒石酸会使得强度下降得更为明显，0.3%（质量分数）掺量时便会使得1 d抗压强度下降10.9 MPa，0.6%掺量时28 d抗压强度下降27.3 MPa。掺0.6%硼砂的1 d试样中钙矾石的形貌未发生明显变化，但生成量减少5.31%；葡萄糖酸钠使钙矾石呈短柱状，生成量几乎不变；L（+）-酒石酸使得钙矾石呈针状，生成量无明显变化。-10 ℃条件下硼砂可显著延长快硬硫铝酸盐水泥的凝结时间，且适当掺量时强度损失可接受，是适宜的缓凝剂；葡萄糖酸钠、L（+）-酒石酸的缓凝效果不明显，且会改变钙矾石的形态与分布，并会使强度显著下降。

研究了-10 ℃环境中氯化钙溶液拌合冷物料条件下，硼砂、葡萄糖酸钠、L（+）-酒石酸对快硬硫铝酸盐水泥凝结硬化行为、强度发展的影响，分析了缓凝剂对水化产物的影响。结果表明：-10 ℃条件下采用氯化钙溶液拌合时，0.6%掺量硼砂可使初凝时间延长至25 min、终凝时间延长至28 min，而葡萄糖酸钠和L（+）-酒石酸对初终凝时间影响不显著。随着硼砂、葡萄糖酸钠掺量的增加，不同龄期强度均逐渐下降，28 d最大降低值可达到25.5 MPa；L（+）-酒石酸会使得强度下降得更为明显，0.3%（质量分数）掺量时便会使得1 d抗压强度下降10.9 MPa，0.6%掺量时28 d抗压强度下降27.3 MPa。掺0.6%硼砂的1 d试样中钙矾石的形貌未发生明显变化，但生成量减少5.31%；葡萄糖酸钠使钙矾石呈短柱状，生成量几乎不变；L（+）-酒石酸使得钙矾石呈针状，生成量无明显变化。-10 ℃条件下硼砂可显著延长快硬硫铝酸盐水泥的凝结时间，且适当掺量时强度损失可接受，是适宜的缓凝剂；葡萄糖酸钠、L（+）-酒石酸的缓凝效果不明显，且会改变钙矾石的形态与分布，并会使强度显著下降。

The effects of borax, sodium gluconate and L(+)-tartaric acid on the hardening behavior and strength development of rapid-hardening calcium sulphoaluminate cement mixed with calcium chloride solution at -10 ℃ were investigated. The results show that the initial and final setting time of rapid-hardening calcium sulphoaluminate cement mixed with calcium chloride solution prolonge to 25 min and 28 min with 0.6% borax at -10 ℃, respectively. However, the setting time of pastes with sodium gluconate or L(+)-tartaric acid does not extremely change. The strength gradually decreases in the samples with increasing the dosages of borax and sodium gluconate at different ages. A maximum reduction of 25.5 MPa occurs in those samples. The strength of samples containing L(+)-tartaric acid sharply decreases. A reduction of 10.9 MPa in 3-day samples containing 0.3% tartaric acid and 27.3 MPa in 28-day samples containing 0.6% tartaric acid occur. The presence of 0.6% borax does not change the morphology of ettringite at 1 d, but decreases the amount of ettringite by 5.31%. A short column-like ettringite in the samples with sodium gluconate and a needle-shaped-like ettringite in the samples with L(+)-tartaric acid are detected, respectively. However, the amount of ettringite in those two samples above has no remarkable change. Borax is a suitable retarder for calcium sulphoaluminate cement at -10 ℃ because of the feasibility of setting prolongation and the acceptable strength reduction. Sodium gluconate and L(+)-tartaric acid have a slight effect on the setting time but change the ettringite morphology and deteriorate the strength.
