摘要
研制了由高效减水剂、早强剂、膨胀剂、阻锈剂等组成的ＹＺ-７复合外加剂，并将其与４２５Ｒ普通水泥和中砂配制成灌浆材料。应用结果表明，这种灌浆料具有高强、早强、微膨胀、流动性大的特点，对钢材无腐蚀，施工方便，成本低，能较好地满足现场施工的要求。
Based on the experimental studies, a new compopsite admixture composed of water reducer accelerating agent, expansion agent, corrosion resistant agent are prepared. The application results show that the grouting material made of this composite admixture, 425R ordinary cement and medium sand has the properties of high strength, early strengthening, a little expansion, great fluidness, non-corrosiveness to steels and low cost. This grout can satisfy the requirement of construction in site.
