道路混凝土早强低脆性能

Performance of Early Strength and Low Brittleness of Pavement Concrete

混凝土是一种脆性材料 ,当提高其强度时 ,它的脆性会有较大幅度增大 ,这限制了它在工程结构中的进一步应用。通过实验研究 ,利用自配的复合减水剂 ,使道路混凝土的早期强度提高 ,脆性降低 ,并对其增强降脆机理进行了探讨。

Concrete is a kind of brittle material, increasing its strength will result in the rising of brittleness, which restrict its further application in engineering structures. Through experiments and research, the compound water reducing admixture prepared by authors can not only increase the early strength of road concrete and reduce its brittleness,but also increase the durability of concrete. Its mechanism is analyzed.
