超早强修补混凝土路用性能研究

Study on the road performanee of the conerete with super-rapid strength agent

本文通过大量试验研究 ,成功地研制开发出水泥混凝土路面板块超早强修补材料 HW系列修补剂。试验结果表明 ,该系列修补剂不仅可使普通水泥混凝土在 6h内抗折强度达到 3 5MPa以上 ,后期强度不衰减 ,并能使混凝土保持较低的脆性和抗折弹性模量 ;试验结果同时表明 。

Based on the indoor tests and researches, the super rapid mending material, one series of the HW mending agents, is successfully developed for the cement concrete pavementdecks. The experiment result show that the fiexural strength of the cement concretetreated with this mending material can reach 3.5MPa within 6h without lowering its latestrength. At the same time, the brittleness and temperature shrinking of concrete can bedecreased, but the ruptnre modulus and ffiction resistance are increased. 〔
