摘要

介绍了在公路路面施工中使用高效减水剂西卡塑-88生产含砂混凝土的效果。由于天然粗河砂的稀缺性日益严重，利用破碎砂部分替代天然河砂来配制混凝土势在必行。初步研究表明，含有60-80%的西卡塑钢-88破碎砂的混凝土比含有河砂的混凝土要好得多:提高了抗弯强度和弹性模量，显著降低了施工成本。

Efficiency in using superplasticizer Sika Plastiment - 88 for producing concrete containing manufactured sand in road pavement construction

Efficiency in using superplasticizer Sika Plastiment-88 for producing concrete containing manufactured sand in road pavement construction was presented in this research study. Due to the scarcity of coarse natural river sand more and more seriously, utilizing crushed sand to partially replace natural river sand in making concrete is essential. The initial study provided that the concrete containing 60-80% crushed sand with Sika Plastiment-88 was much better than the concrete containing river sand: Enhancing flexural strength and elastic modulus, reducing significantly construction costs.
