摘  要：
本文通过研究不同浓度的NH_4HCO_3、KH_2PO_4和NH_4H_2PO_4降碱溶液对植被混凝土的pH值影响,提出复合降碱技术,并研究复合降碱溶液对植被混凝土pH、强度、透水系数等性能的影响,结果证明该技术可将孔隙液的pH值快速降低至植被生长需求的范围并维持较长时间,提高混凝土强度6%~10%,不降低透水性能;针对北方地区的气候和土壤特点,优选出植被混凝土中长势旺盛的植被。此技术工艺简单,成本低,可促进绿色生态植被混凝土的推广应用。

摘  要：
Compound alkali reducing technology was put forward by studying the impact of the different concentrations of NH_4HCO_3, KH_2PO_4 and NH_4H_2PO_4 of alkaline solution on PH value of vegetation concrete. The effects of compound alkali reducing solution on p H, 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.
