The invention discloses a metamorphic rock concrete preparation method and a commercial concrete regeneration process thereof. The metamorphic rock concrete preparation method comprises the following steps: S1, pretreatment; s2, preparing coarse aggregate; s3, preparing fine aggregate; s4, weighing is carried out; and S5, mixing and stirring. According to the invention, the metamorphic rock is processed to prepare the coarse aggregate and the fine aggregate used by the concrete, so that the local metamorphic rock material can be directly used when engineering construction is carried out in a region taking the metamorphic rock as a main region, thereby effectively reducing the transportation pressure and the cost pressure of the construction material, and being adjusted to local conditions and reasonably utilized. The waterproof agent is added into the concrete mixture, so that the waterproof effect of the formed concrete is effectively improved, contact between water and wet air and the interior of the concrete is isolated, alkali-aggregate reaction of the concrete is effectively inhibited, meanwhile, the mineral admixture is added, the alkali content in the mixture is reduced, and the service life of the concrete is prolonged. The alkali aggregate reaction effect of metamorphic rock can be further inhibited, so that the produced concrete has the characteristics of freezing resistance, cracking resistance and high stability.
本发明公开了一种变质岩混凝土制备方法及其商砼混凝土再生工艺，包括以下步骤：S1、预处理；S2、粗骨料制备；S3、细骨料制备；S4、称重；S5、混合搅拌。本发明通过对变质岩进行加工制成混凝土所用的粗骨料和细骨料，实现在以变质岩为主地区进行工程建设时，可以直接使用当地的变质岩材料，从而有效降低建设材料运输压力、成本压力，因地制宜，合理利用。本发明通过在混凝土混料中添加防水剂，从而有效提高混凝土成型以后的防水效果，进而隔绝水和湿空气与混凝土内的接触，有效抑制其碱骨料反应，同时，通过加入矿物掺合料，减少混合料中的碱含量，也能进一步抑制变质岩的碱骨料反应的效果，使得生产出的混凝土具有防冻、防裂、稳定高的特点。
