Abstract

The invention relates to plant growth type ecological concrete used for slope protection and a preparation method of the concrete, and belongs to the technical field of environmentally-friendly materials. The concrete and method disclosed by the invention utilize waste clay brick aggregate, the waste clay brick aggregate has the characteristics of certain strength and continuous gaps, the aggregate is crushed and covered by cement mortar for strengthening treatment, the used cement mortar includes nutrients such as soluble silicon, calcium and magnesium and a plurality of microelements, a compound fertilizer can increase soil fertility and improve a content of nitrogen, phosphorus and potassium in soil, ferrous sulfate is used to neutralize alkalinity of plant-growth type porous concrete,so that a planting substrate in the porous concrete can adapt to plant growth; and in the hardened concrete, sodium polyacrylate resin that is in contact with one another forms communicating space forgrowth of plant roots, and the sodium polyacrylate resin provides moisture and nutrients for plant growth, can be repeatedly accumulated and release moisture after rainfall or spraying is performed,play an inner curing role on the concrete, reduce shrinkage cracking and improve strength.

Description

technical field [0001] The invention relates to a plant-growing ecological concrete for slope protection and a preparation method thereof, belonging to the technical field of environmental protection materials. Background technique [0002] With the expansion of the urban area in our country, the safety, ecological and environmental problems of lakes and rivers are becoming more and more serious. For the ecological slope protection works of rivers and lakes, traditional concrete slopes often have ecological and environmental problems, which can no longer meet the needs of today's social development. Lake and river projects have faced safety and ecological dilemmas, and are facing more and more serious safety, ecological and environmental problems. How to make bank revetment materials and technologies more scientific has become a matter of great concern to scientific researchers and technicians. Vegetative concrete is a new, green and environmentally friendly concrete materi...
