In response to the imbalance of the regional ecological environment due to the destruction of the original geographical features and vegetation in the process of basic engineering construction in China in recent years，we research the ecological grass-planting concrete and its construction technology with both ecological protection and slope protection functions. Using low-alkalinity special materials，large-size aggregates，and optimized mix design methods，we make the ecological grass-planting concrete with strength≥7.0 MPa，porosity≥30%，and alkalinity pH≤9.0 to meet the basic requirements of the plant growth. Based on the indoor test and model test，and relying on the overall development of the PPP project in the industrial new city of Qingshuitang Old Industrial Zone in Zhuzhou City，we determined the key construction technology of ecological grass-planting concrete and successfully applied it to the slope engineering. The 90-day vegetation coverage rate after slope treatment was 95.3%，which effectively solved the hidden dangers of landslides and greening problems.
