Preparation process of high-strength recycled aggregate concrete
The invention relates to the technical field of building materials, in particular to a preparation process of high-strength recycled aggregate concrete. The preparation process comprises the following steps: sorting the aggregate; granulating and carbonizing the lightweight aggregate; soaking the heavy aggregate; and preparing the high-strength recycled aggregate concrete. The superfine slag powder, the construction waste, the lime and the desulfurized fly ash are mixed to prepare the cementing material with bonding performance, and the cementing material is added into the lightweight aggregate, so that the lightweight aggregate has certain bonding performance, relatively light lightweight aggregate powder can be bonded with one another, better granulation is realized, and the prepared cementing material is relatively low in viscosity, and is not prone to cracking. The concrete can prevent overlarge particles caused by direct excessive bonding of the lightweight aggregate, and the lightweight aggregate with proper particle size can be used for filling gaps among the heavy aggregate and is better bonded with the heavy aggregate, so that the internal combination of the concrete is tight, and the compression resistance is better.
本发明涉及建筑材料技术领域，具体涉及一种高强度再生骨料混凝土的制备工艺。其制备工艺包括以下步骤：骨料分选；轻骨料造粒碳化处理；重骨料浸泡处理；制备高强度再生骨料混凝土。本发明通过将矿渣微粉、建筑废弃物、石灰与脱硫灰混合制备具有粘合性能的胶结料，并向轻骨料中加入胶结料，从而使得轻骨料之间具有一定粘合性，相对较轻的轻骨料粉末能够互相粘合，从而更好地造粒，并且，制备得到的胶结料粘性较小，能够防止轻骨料直接过度粘合导致颗粒过大，颗粒粒度适合的轻骨料可以用于填充重骨料之间的缝隙，并且与重骨料更好地粘合在一起，从而使得混凝土内部结合紧密，抗压性能更好。
