Preparation method of nano attapulgite recycled concrete
The invention discloses a preparation method of nano attapulgite recycled concrete, and belongs to the field of building materials. The nano attapulgite recycled concrete is prepared from the following components in parts by weight: 520-570 parts of cement, 0-50 parts of nano attapulgite, 660 parts of natural fine aggregate, 0-1100 parts of natural coarse aggregate, 0-1100 parts of recycled coarse aggregate, 260 parts of water, and 0-20 parts of additional water. The preparation method further comprises the following steps: S1, uniformly stirring the cement, the sand and the coarse aggregate to form a mixture; S2, adding nano attapulgite into water, and dispersing the nano attapulgite in the water for 10 minutes by adopting a mechanical stirring method to form turbid liquid; and S3, uniformly mixing and stirring the step S1 and the step S2 to obtain the nano attapulgite recycled concrete. According to the invention, waste concrete blocks are crushed to partially or completely replace coarse aggregate, so that the environmental pollution caused by construction waste is solved, and the problem of over-exploitation of natural aggregate is relieved.
本发明公开了一种纳米凹凸棒石再生混凝土制备方法，属于建筑材料领域，包括水泥、纳米凹凸棒石、天然细骨料、天然粗骨料、再生粗骨料、水和附加水制备得到，所述的水泥520～570份，纳米凹凸棒石0～50份，天然细骨料660份，天然粗骨料0～1100份，再生粗骨料0～1100份，水260份，附加水0～20份，还包括如下步骤：S1.将水泥、砂、粗骨料搅拌均匀形成混合物；S2.将纳米凹凸棒石加入到水中，采用机械搅拌的方法在水中分散10min，形成悬浊液；S3.将步骤S1和步骤S2混合搅拌均匀后，得到所述纳米凹凸棒石再生混凝土；本发明将废弃混凝土块进行破碎，部分取代或全部取代粗骨料，解决了建筑垃圾对环境污染，以及缓解天然骨料过度开采问题。
