Description

technical field [0001] The invention relates to the field of civil engineering materials, in particular to a plant-growing porous concrete with low alkalinity. Background technique [0002] At present, the technologies used in slope protection in my country mainly include: hard and dense slope protection technology, hole type slope protection technology, and natural vegetation slope protection technology. However, the hard dense slope protection has a hard texture, dark color, and poor visual effect. Moreover, the hard dense slope protection has small porosity and strong alkalinity, which blocks the material and energy exchange between the slope surface and the air, and destroys the surface of the slope surface. The ecological environment required for plant growth. The perforated slope protection technology has high requirements on the design of the perforations. If the perforations are too small, there will be little room for plant growth. If the perforations are too large...
