Super high-rise pumping pipeline moistening cement paste
The invention relates to the field of pumping concrete, and particularly discloses a super high-rise pumping pipeline moistening cement paste. The super high-rise pumping pipeline moistening pipe neat cement paste comprises the following components in parts by weight: 1000-1400 parts of cement, 1-10 parts of a rheology modifier, 400-600 parts of water, 5-15 parts of a water reducing agent and 200-400 parts of fly ash. The preparation method comprises the following steps: stirring and mixing the cement and the fly ash to obtain a dry mixture, adding the water into a stirring container, and continuously stirring to form uniform slurry; and adding the weighed water reducing agent and rheological modifier into the slurry, and stirring for 20-30 minutes to form the uniform and particle-free cement paste. The super high-rise pumping pipeline moistening neat cement paste has the advantages that a layer of lubricating film can be formed on the inner wall of a pumping pipeline, so that the resistance of concrete in the pumping process is reduced, and pipe blockage is prevented.
本申请涉及泵送混凝土领域，具体公开了一种超高层泵送管道润管水泥净浆。超高层泵送管道润管水泥净浆包括重量份计的水泥1000‑1400份、流变调节剂1‑10份、水400‑600份、减水剂5‑15份、粉煤灰200‑400份；其制备方法为：先将水泥和粉煤灰进行搅拌混合，得到干混料，再将水加入到搅拌容器中，同时持续搅拌，形成均匀的浆体；将称取好的减水剂和流变调节剂加入到浆体中，搅拌20‑30min，形成均匀、无颗粒的水泥净浆。本申请的超高层泵送管道润管水泥净浆具有能够在泵送管道内壁形成一层润滑膜，以减少混凝土在泵送过程中的阻力，防止堵管优点。
