摘要:

筛选了有代表性的水泥、流化剂和高效不分散剂,采用水下不分散混凝土配制技术,配制出了施工性能优良的水下混凝土。在分析其流动性、工作性能和力学性能的基础上,研究了水下混凝土的耐久性,通过抗渗试验、氯离子电荷量试验和氯离子扩散系数试验对水下混凝土的耐久性进行了评价。研究结果表明:水下不分散混凝土的强度、变形性能均满足施工要求; 水下不分散混凝土氯离子的电荷量均小于1 000 C,氯离子扩散系数小于3.0×10^-12 m²·s^-1,耐久性优良,该技术指标高于中国相关规范标准,满足技术和工程要求。

Abstract:

Authors filtrated representative cement,liquid agent and high efficency nondispersible agent,adoptingnondispersible concrete mixture technology. Mixture construction performance choiceness underwater concrete was compounded. Based on Analyzing flowing, workability and physics mechanics capability,authors emphatically studied underwater concrete durability, adopting resistance seeping test,chlorin ion electricity flux test and chlorin ion pervasion coefficient test to appraise underwater concrete durability performance. The results show that underwater nondispersible concrete strengh, deformation capability satisfy requirement, chlorin ion electricity flux of underwater nondispersible concrete is less than 1000 coulomb, chlorin ion pervasion is less than 3.0×10^-12 m²·s^-1, durability capability is choice, the technique guide line is more than correlation Chinese code, and satisfies technique and engineering requirement.
