Abstract：Through the analysis of calculation standard and evaluation method of carbon emission of ready-mixed concrete，as well as the analysis and research of carbon emission source and carbon reduction technology path of ready-mixed concrete，this paper summarizes the calculation process of carbon emission，the existing problems，and part of the research results of carbon reduction in the industry. Suggestions on low-carbon technology are proposed. All local administrative regions should actively design local carbon emission standards based on regional characteristics. The gradation and morphology of aggregate should be fully considered，and the gradation design of rubber material system should be combined to achieve close packing of whole particles. The coordination effect of solid waste and cement clinker should be fully played to realize the reduction application of cement clinker. The ready-mixed concrete mixing station should gradually achieve intelligent operation，minimize the amount of self-produced waste or realize recycling. Transportation system and construction project schedule control to achieve organic integration，reduce the vehicle's worthless running time. Indirect carbon reduction technology and factory-style carbon absorption design should be considered comprehensively in the ready-mixed concrete mixing plant to truly realize zero-emission production.
