生态多孔混凝土与不同植被品种的化学相容性研究
Research on chemical compatibility of ecological porous concrete and different vegetation species
摘要
Abstract
The changing regularity of germination rate, morphological characteristics, growth height and damage status of different vegetation species influenced by the internal pore pH value of ecological porous concrete were studied, including bermuda grass, festuca elata keng, bluegrass and ryegrass. The ecological porous concrete was treated by alkali lowering processing technology with different ferrous sulfate concentration solution. The test results show that when the internal pore pH value of eco-porous concrete is between 6.5 and 7.5, the growth and physiological indexes of four kinds of species reach the best. The critical conditions for the alkalinity of the chemical compatibility between the four kinds of species and the ecological porous concrete were investigated, and it can provide a reliable theoretical basis for the vegetation selection under different alkaline environments. The research results also provide reliable technical support for the application of green ecological concrete.关键词
