Super high-rise pump concrete and preparation method thereof
The invention relates to the field of pump concrete, in particular to super high-rise pump concrete and a preparation method thereof. The super high-rise pump concrete is prepared from the following raw materials in parts by weight: 155 to 175 parts of cement, 140 to 160 parts of water, 1 to 10 parts of an additive, 1050 to 1200 parts of coarse aggregate, 700 to 800 parts of fine aggregate, 150 to 200 parts of a mineral admixture and 30 to 50 parts of a mixture, the mixture comprises ceramsite, polyacrylamide and silicon dioxide, and the weight ratio of the ceramsite to the polyacrylamide to the silicon dioxide is 1: (0.05-0.2): (0.2-0.5). The super high-rise pumping concrete provided by the invention has the advantages of high performance, good pumpability, strong flowability and the like.
本申请涉及泵送混凝土领域，更具体地说，它涉及一种超高层泵送混凝土及其制备方法。一种超高层泵送混凝土，按照重量份数，包括以下原料：155‑175份水泥、140‑160份水、1‑10份外加剂、1050‑1200份粗骨料、700‑800份细骨料、150‑200份矿物掺合料、30‑50份混合物；混合物包括陶粒、聚丙烯酰胺、二氧化硅，陶粒、聚丙烯酰胺、二氧化硅的重量比为1：（0.05‑0.2）：（0.2‑0.5）。本申请所提供的超高层泵送混凝土具有高性能、可泵性佳、流动性强等优点。
