Calcined hwangtoh is a pozzolanic material that is increasingly being used as a mineral admixture in the concrete industry. This study shows a hydration model for cement–hwangtoh blends and evaluates the various properties of hwangtoh-blended concrete using reaction degrees of binders. First, a kinetic reaction model is proposed for analyzing the pozzolanic reaction of hwangtoh. The reaction of hwangtoh includes three processes: the initial dormant period, boundary reaction process, and diffusion process. The mutual interactions between the binary reactions of cement and hwangtoh are thought to be in line with the items in capillary water and calcium hydroxide. Second, the reaction degrees of cement and hwangtoh are determined based on a blended hydration model. Furthermore, the chemical (chemically combined water and calcium hydroxide contents), mechanical (compressive strength), thermal (hydration heat), and durability aspects (carbonation depth) of hwangtoh-blended concrete are systematically predicted. The results show good agreement with experimental results.

煅烧的黄土是一种火山灰材料，在混凝土工业中越来越多地用作矿物掺合料。这项研究显示了水泥-黄to混合料的水化模型，并根据粘结剂的反应程度评估了黄to掺合混凝土的各种性能。首先，建立了动力学反应模型来分析黄土的火山灰反应。黄wang的反应包括三个过程：初始休眠期，边界反应过程和扩散过程。水泥和黄土的二元反应之间的相互作用被认为与毛细管水和氢氧化钙中的元素相符。其次，根据混合水化模型确定水泥与黄土的反应程度。此外，化学物质（化学结合的水和氢氧化钙的含量）系统地预测了hwangtoh混合混凝土的机械（抗压强度），热（水化热）和耐久性方面（碳化深度）。结果与实验结果吻合良好。
