Plastering mortar based on waste clay brick material and preparation method thereof
The invention belongs to the technical field of building materials, and relates to plastering mortar based on a waste clay brick material and a preparation method of the plastering mortar, the preparation method comprises the following steps: crushing, grinding and screening waste clay bricks to obtain waste clay brick particles and waste clay brick powder, uniformly mixing the waste clay brick powder, cement and a defoaming agent to form a dry mixture, mixing water, an emulsion and the dry mixture, and uniformly stirring to obtain the plastering mortar based on the waste clay brick material. And adding the waste clay brick particles, and uniformly mixing to obtain the waste clay brick plastering mortar. Compared with the prior art, the waste clay bricks are recycled, crushed and ground and then screened according to different particle sizes, obtained fine brick particles are compounded and then used as fine aggregate, and fine sand can be replaced by 100%; the waste clay brick powder with smaller particle size generated in the crushing and grinding process is used as a substitute of cement, and at most 20% of cement can be replaced. In addition, the polymer emulsion and the defoaming agent are matched to adjust the workability of the mortar, so that the preparation of the plastering mortar is realized. The maximum recycling of the waste clay bricks is realized, and the production process is simple.
本发明属于建筑材料技术领域，涉及一种基于废粘土砖材料的抹灰砂浆及其制备方法，制备方法包括：将废粘土砖破碎、粉磨、筛分得到废粘土砖颗粒和废粘土砖粉，将废粘土砖粉、水泥、消泡剂混合均匀，形成干混料，将水、乳液、干混料进行拌和，再加入废粘土砖颗粒拌合均匀，得到废粘土砖抹灰砂浆。与现有技术相比，本发明将废粘土砖回收、破碎、粉磨后，按照不同粒径进行筛分，所得细砖颗粒复配后用作细骨料，可实现100％替代细砂；将破碎粉磨过程中产生的粒径更细小的废粘土砖粉用作水泥的替代物，至多可取代20％水泥。此外，配合聚合物乳液和消泡剂调节砂浆的工作性，由此实现抹灰砂浆的制备。实现废粘土砖的最大化回收利用且生产工艺简单。
