摘要
通过对应用减胶剂的混凝土工作性能、力学性能和耐久性对比试验,发现混凝土减胶剂可改善混凝土坍落度和扩展度,在保持水胶比相同、混凝土抗压强度不受影响的情况下,可降低10%甚至更多的水泥用量,同时混凝土的抗碳化、抗硫酸盐侵蚀等耐久性指标良好。
This paper studies the influence of cement-reducing admixture on the workability,mechanical properties and durability of concrete.The results show that the material can improve the slump and expansion of concrete;it can reduce 10%or even more cement dosage under the condition of keeping the same water binder ratio and the compressive strength.At the same time,the durability indexes such as carbonation resistance and sulfate corrosion resistance are good.
