There are many types of ecological concrete,and through a large number of indoor and outdoor tests,this paper proposes a plant-compatible ecological concrete model with strong practicability and reasonable economy.Common limestone gravel is selected to form an intermittent graded cement gravel structure,and some acidic curing liquid is appropriately sprayed to neutralize the alkalinity in the concrete,creating a neutral environment suitable for herbaceous growth,and the effect is good through long-term tracking observation and simulated slope protection test.Finally,the strength reduction theory is used to compare and analyze the stability coefficient of ecological concrete slope protection.
