Outdoor Vegetation Test Study of Performance Optimization of Recycled Aggregate Planting Concrete
Besides meeting the basic requirements of compressive strength and connecting porosity,recycled aggregate planting concrete requires a suitable alkali environment for plants and vegetative substrates for grasses.This paper optimized the concrete alkali vegetative environment and appropriate vegetative substrates to study the planting effect of recycled aggregate planting concrete.It was concluded that the grass species of indoor planting concrete could be rooted and germinated,especially perennial ryegrass grew faster than the bermudagrass;the grass mixed seeding had a better effect than the single seeding,and the root system was developed well after the alkali reduction;the growth states of plants without concrete was slightly better than that of plants with concrete and alkali reduction;based on the criteria of lawn appearance quality,after 60 days,the perennial ryegrass,tall fescue,and bermudagrass were better in terms of color,uniformity,and density.
