Long-distance pumping concrete as well as preparation method and application thereof
The invention relates to the technical field of concrete, in particular to long-distance pumping concrete as well as a preparation method and application thereof, and the long-distance pumping concrete comprises the following raw materials in parts by weight: 310-340 parts of cement, 50-60 parts of slag powder, 75-90 parts of fly ash, 820-850 parts of mixed sand, 880-920 parts of stone, 7.5-9 parts of a water reducing agent and 165-180 parts of water. Wherein the mixed sand is prepared by mixing machine-made sand and natural sand, and the weight part ratio of the machine-made sand to the natural sand is (410-430): 418; the pebbles are prepared by mixing two kinds of pebbles with the continuous particle size of 5-25 mm and the continuous particle size of 5-10 mm according to the weight part ratio of (490-520): 400; the long-distance concrete pumping device has the advantage that the problem of pump blockage caused by long-distance concrete pumping can be well solved.
本申请涉及混凝土的技术领域，涉及一种长距离泵送混凝土及其制备方法和应用，所述长距离泵送混凝土包括如下重量份的原料：水泥310‑340份、矿渣粉50‑60份、粉煤灰75‑90份、混合砂820‑850份、石子880‑920份、减水剂7.5‑9份和水165‑180份；其中，所述混合砂由机制砂和天然砂混合制得，其机制砂和天然砂的重量份比为（410‑430）：418；所述石子由两种连续粒级为5‑25mm和5‑10mm按照重量份比为（490‑520）：400混合制得；其具有能够较好的解决长距离泵送混凝土的堵泵问题的优点。
