| 摘 要： | 为了提高水泥胶砂的力学性能,提出在水泥胶砂中掺加外加剂的方法,通过在水泥胶砂中单掺引气剂、复掺引气剂与减水剂两种途径,进行水泥胶砂抗折强度检测试验,对比确定水泥胶砂力学性能最优的引气剂型号及其最佳掺量.结果表明:引气剂与减水剂复掺时水泥胶砂的抗折强度明显大于引气剂单掺时水泥胶砂的抗折强度,2#引气剂最能满足水泥胶砂抗折强度要求.

| Abstract: | In order to improve the mechanical property of cement mortar, admixtures are pro-posed to be put into cement mortar by adding air-entraining agent separately or mixing air en-training agent and water-reducing agent. The bending strength test of cement mortar has been done. The best model and the optimal dosage of air entraining agent in cement mortar have been determined for its optimal mechanical property. The result shows that the bending strength of cement mortar is significantly greater when air entraining agent and water-reducing agent are mixed. 2 # air-entraining agent has better effect in meeting the requirements of the bending strength of cement mortar. |
