Modified recycled aggregate as well as preparation method and production device thereof
The invention belongs to the technical field of building materials, and particularly discloses modified recycled aggregate as well as a preparation method and a production device thereof. The preparation method of the modified recycled aggregate comprises the following steps: soaking the recycled aggregate in a nano silicon dioxide solution for the first time, and setting an electric field in the solution; removing the nano silicon dioxide solution, and adding a magnesium oxide solution for soaking; and removing the magnesium oxide solution, soaking the recycled aggregate in the nano silicon dioxide solution for the second time, and heating to 40-95 DEG C to obtain the modified recycled aggregate. The invention also provides a production device of the modified recycled aggregate, the modified recycled aggregate and recycled aggregate concrete. According to the preparation method, the modification period is short, the production efficiency is greatly improved, industrial production is guaranteed, the water absorption rate and the crushing index of the prepared modified recycled aggregate are greatly reduced, the apparent density of the modified recycled aggregate is improved, and the modified recycled aggregate has an excellent application prospect.
本发明属于建筑材料技术领域，具体公开了一种改性再生骨料及其制备方法和生产装置。本发明的改性再生骨料的制备方法，包括以下步骤：将再生骨料进行第一次纳米二氧化硅溶液浸泡，并在溶液中设置电场；去除纳米二氧化硅溶液，加入氧化镁溶液浸泡；去除氧化镁溶液，将再生骨料进行第二次纳米二氧化硅溶液浸泡，加热温度至40～95℃，即得改性再生骨料。本发明还提供一种改性再生骨料的生产装置和改性再生骨料以及再生骨料混凝土。本发明制备方法的改性周期短，大幅提升生产效率，保障工业化生产，本发明制备的改性再生骨料大幅降低了再生骨料的吸水率和压碎指标，提升其表观密度，具有极佳的应用前景。
