增强料的组分对透水混凝土性能的影响

Effect of Reinforcing Agent Composition on Performance of Permeable Concrete

增强料主要用于提高透水混凝土的抗压强度、抗折强度和抗渗性能。本文研究了增强料中的减水组分、早强组分以及增粘组分对透水混凝土性能的影响。通过改变各种组分的种类及掺量,研究了对透水混凝土的抗压强度、抗折强度以及透水系数和透水率的影响。试验结果表明,增强料中采用0.3%的聚羧酸减水剂,1.0%的早强剂和0.1%的增粘剂可明显提高透水混凝的各项性能。

The reinforcing agent is used for improving compressive strength, flextural strength and penetration of permeable concrete. The effects of water reducing composition,early strength compositiont and viscosity modifying compositon on the performance of permeable concrete were studied. The compressive strength,flexural strength,and the permeability coefficient and the water permeability of the permeable concrete were measured by changing types and content of the various components in the reinforcing agent. The experimental results show that the preformence of concrete with the reinforced agent by 0. 3% of polycarboxylic superplasticizer,1. 0% of early strength increasing agent and 0. 1%viscosity is more better.
