【摘要】 主要研究了不同减水剂以及复掺减缩剂对ECC基本力学性能的影响,试验结果表明,单掺减水剂会对ECC的抗压强度带来负面影响,但适量的减水剂掺入拌合物中可以提高其抗折强度;减水剂复掺减缩剂后,ECC抗压强度维持不变,抗折强度可以提升24.1%。更多还原

【Abstract】 Studied the mechanical behavior of ECC effected by different water reducing agents and the mixture of both shrinkage reducing agent and water reducing agent.The results showed that the single doped water reducing agent brings negative effect on the compressive strength of ECC,while appropriate dosage of water reducing agent can improve its flexural strength.With the mixture of both shrinkage reducing agent and water reducing agent,the compressive strength of ECC can be maintained and its flexural strength canbe enhanced 24.1%.更多还原
