摘要
研制出性能优良的新型混凝土水下不分散剂 NDA,利用 NDA配制出 C40高性能水下不分散混凝土 .NDA具有工作性好、强度损失低、抗分散性能好等优点 ;掺加 NDA的新拌水下不分散混凝土抗分散性能好 ,能自流平、自密实 ,无泌水 ;硬化水下不分散混凝土强度高、抗分散 ,抗冲磨、抗渗。
A novel non-disperse additive NDA for high performance underwater concrete was developed in this paper. A superior C40 non-disperse underwater concrete was prepared using the additive. The properties of the additive and the performances of the resulting underwater concrete in practical application were investigated. The results certified the advantages of NDA non-disperse additive in terms of low strength loss and high dispersion-resistance. The fresh underwater concrete added with the additive exhibits desirable characteristics such as high dispersion-resistance, self-leveling ability, self-compacting ability and water-proof ability. The hardened concrete showed superior performances with respect to its high strength, dispersion-resistance, wear-resistance, permeation-resistance and corrosion-resistance.
