利用外加剂技术提高加气混凝土抗压强度的试验研究

Experimental Research on Utilizing Admixture Technology to Enhance Compressive Strength of Air-entraining Concrete

利用四种不同外加剂分别按不同比例掺入加气混凝土中进行抗压强度试验,试验表明掺入适量的外加剂能有效地提高加气混凝土抗压强度,分析了掺入外加剂后加气混凝土强度提高的机理,探讨了利用加气混凝替代粘土砖作为砌体结构承重墙体材料的可行性.

Compressive strength experiment is conducted by adding four different admixtures into air-entraining concrete at different proportion respectively. The results show that adding an appropriate admixture can improve the compressive strength of air-entraining concrete. On these grounds, this paper analyses the mechanism of the improvement of compressive strength of air-entraining concrete with an admixture and then pints out the practicability of using air-entraining concrete to replace clay-brick as load-bearing materials of masonry structure.
