A method for designing component proportion of a full-solid-waste-slag-based cementitious material and a production system thereof

Abstract

This invention discloses a method and production system for designing the proportioning of solid waste slag-based cementitious materials, relating to the field of concrete mix design technology. The method first determines the main chemical components of solid waste raw materials such as slag, sulfate donors, and alkali activators through XRF spectral analysis. Then, based on the target hydration products, it derives the main chemical reaction equations of the system to determine the optimal molar ratio of each key chemical component. Furthermore, considering the purity of the raw materials, this molar ratio is converted into the optimal mass proportioning ratio among slag, sulfate donors, and alkali activators. Finally, a small amount of early-strength agent (such as alkali metal or sulfate-based agents) is added to meet different engineering requirements. The corresponding production system integrates online component detection, intelligent proportioning calculation, and automatic control functions, enabling real-time optimization of the proportioning based on fluctuations in raw material composition, achieving efficient, precise, and automated production of materials. This invention realizes the resource utilization of all solid waste raw materials, and the design process is scientific and controllable.
