Dry-mixed adhesive mortar and preparation method thereof
The invention discloses a dry-mixed adhesive mortar and a preparation method thereof. The preparation method comprises the following steps: mixing cement, recycled micro powder and recycled fine aggregate to obtain a mixture M1; adding cellulose ether into the mixture M1 to obtain a mixture M2; and adding rubber powder into the mixture M2 to obtain the dry-mixed adhesive mortar, wherein relative to 100 parts by weight of cement, the use amount of the recycled micro powder is 30-50 parts by weight, the use amount of the recycled fine aggregate is 150-200 parts by weight, the use amount of the rubber powder is 3-5 parts by weight, and the use amount of cellulose ether is 0.3-1 part by weight. The invention further provides the dry-mixed adhesive mortar which is prepared by the preparation method and has a good adhesive property.
本发明公开一种干混粘结砂浆及其制备方法，其中，所述制备方法包括：将水泥、再生微粉和再生细骨料混合，得到混合物M1；向混合物M1中加入纤维素醚，得到混合物M2；向混合物M2中加入胶粉，得到干混粘结砂浆。其中，相对于100重量份的水泥，再生微粉的用量为30‑50重量份，再生细骨料的用量为150‑200重量份，胶粉的用量为3‑5重量份，纤维素醚的用量为0.3‑1重量份。本发明还提供了一种根据上述的制备方法制得具有良好的粘结性能的干混粘结砂浆。
