核电水泥复合疏水化合孔栓物用于大体积混凝土性能研究

Research on the Performance of Portland Cement for Nuclear Power Engineering Cooperate Hydrophobic Poreblocking (HPI) Ingredient of Mass Concrete

研究核电水泥复合疏水化合孔栓物对大体积混凝土的抗裂缝性能和耐久性的影响。研究表明核电水泥复合疏水化合孔栓物具有很强的抗裂缝性能、抗收缩性能、抗渗性能和抗氯离子渗透性能等耐久性能。该复合物用于虎门二桥大沙水道桥东塔承台,显著提高了承台的抗裂缝性能和耐久性。

Research on the influence of mass concrete of cracking resistance and durability on using portland cement for nuclear power engineering cooperate HPI,The research result shows that they can enhance the cracking resistance、shrinkage resistance、chloride ion’s penetration resistance and other durabilitiies of the concrete.This cooperates was used in the pile caps of east tower of Da Sha bridge in Hu Men second bridge and improved the cracking resistance also the durability obvious.
