Recycled aggregate adhesive mortar and preparation method thereof
The invention relates to recycled aggregate adhesive mortar and a preparation method thereof. The recycled aggregate adhesive mortar comprises the following components in percentage by weight: 110-200 parts of cement, 5-30 parts of limestone powder, 560-720 parts of sand, 60-200 parts of recycled clay brick aggregate, 0.01-0.03 part of a water-retaining thickening agent and 200-300 parts of water, and the water-retaining thickening agent comprises welan gum, xanthan gum and polyethylene glycol 400. The manufacturing method of the recycled aggregate adhesive mortar comprises the following steps: stirring the cement, the limestone powder and the sand; the water-retaining thickening agent and the composite binder are added into water to be fully stirred. The recycled aggregate adhesive mortar prepared by the invention is low in production cost and simple in preparation method; the recycled clay brick aggregate can improve the water retention rate and compressive strength of the mortar; the consumption of natural resources is reduced by using the recycled clay brick aggregate and the limestone powder, the economic cost is low, and the whiteness of the mortar can be improved and the grading of the mortar can be improved by adding the limestone powder; the water-retention thickening agent adopted by the invention can ensure compression resistance and bonding strength, and greatly reduces the cost under the condition that the performance index is qualified.
本发明涉及一种再生骨料粘结砂浆及其制作方法，再生骨料粘结砂浆按重量百分比包括：水泥110‑200份、石灰石粉5‑30份、砂料560‑720份、再生粘土砖骨料60‑200份、保水增稠剂0.01‑0.03份和水200‑300份，保水增稠剂包括温轮胶、黄原胶和聚乙二醇400。再生骨料粘结砂浆的制作方法包括将水泥、石灰石粉与砂料搅拌；将保水增稠剂和复合粘结剂加入到水中充分搅拌。本发明制备的再生骨料粘结砂浆生产成本低，制作方法简单；再生粘土砖骨料能够提高砂浆的保水率和抗压强度；再生粘土砖骨料和石灰石粉的使用减少了天然资源的消耗，经济成本低，加入石灰石粉还可提高砂浆的白度，改善砂浆的级配；本发明采用的保水增稠剂能够保证抗压、粘结强度，在性能指标合格的情况下大大降低成本。
