植被混凝土降碱植生技术优化研究
Research on the Optimization of Vegetation Concrete Alkali Reduction and Vegetation Technology
摘要
Abstract
Compound alkali reducing technology was put forward by studying the impact of the different concentrations of NH4HCO3, KH2PO4 and NH4H2PO4 of alkaline solution on PH value of vegetation concrete. The effects of compound alkali reducing solution on pH, strength and permeability coefficient of vegetation concrete were studied, the result showed this technique can rapidly reduce the pore solution PH value to the range of vegetation growth requirements for a long time and improved concrete strength to 6%-10% without reducing the permeability. According to the climate and soil characteristics in the North. the thriving vegetation in the Vegetation concrete was optimized. The technology can promote the popularization and application of the green ecological vegetation concrete with the simple technical process and low cost.关键词
