绿化混凝土配合比设计方法研究

Research on Mix Proportion Design of Greening-concrete

绿化混凝土新型河流生态护岸技术结合了混凝土护岸和植物护岸的优点,既具有混凝土护岸的力学稳定性、抗冲耐磨的耐久性,又具有植物护岸的渗透性、生物适应性、削污能力、生态保障、景观和休闲娱乐等特性和功能,在河流综合治理中得到广泛的应用。对绿化混凝土配合比参数进行系统研究。研究表明,绿化混凝土的抗压强度与水胶比的关系符合"水灰比定则",随着水灰比增大,抗压强度下降,在一定范围内抗压强度与灰水比呈线性关系。通过试验研究,提出了绿化混凝土配合比设计方法,明确了配合比参数的取值,对绿化混凝土的推广应用具有重要的参考价值。

With the advantages of concrete fiver revetment and vegetation protection, the ecological greening-concrete revetment technology has not only the stability and anti -erosion of concrete but also permeability, biocompatibility, abatement ability, ecological security, the landscape suitability and leisure function of plant revetment. In this paper, the mix ratio parameters of greening-concrete are systematically studied. It has been found out that compressive strength and water cement ratio of greening-concrete consist with the ＂water cement ratio rule＂. With the increase in water cement ratio, compressive strength decreases to a certain extent, compressive strength and cement water ratio are linear. The design method of mix proportion of greening-concrete has been put forward, and the value of mix proportion parameter has been defined.
