C80 concrete for tower drum
The invention discloses C80 concrete for a tower drum, which belongs to the technical field of concrete and is characterized by being prepared from the following raw materials in parts by weight: 420 to 425 parts of cement, 55 to 63 parts of mineral powder, 55 to 65 parts of fly ash, 40 to 50 parts of silica fume, 520 to 535 parts of fine aggregate, 1200 to 1240 parts of coarse aggregate, 5.8 to 6.2 parts of admixture and 135 to 140 parts of water. The admixture comprises a polycarboxylate superplasticizer, a concrete slump retaining agent, sodium citrate and water, and the weight ratio of the polycarboxylate superplasticizer to the concrete slump retaining agent to the sodium citrate to the water is (2.0-2.2): (3.5-4.0): (0.1-0.5): (1.4-1.9), so that after the concrete can be transported for a long distance in a high-temperature environment of about 40 DEG C, the slump loss of the concrete within 3 hours is 0, and the slump loss of the concrete within 3 hours is 0. And various performance indexes of the concrete meet the effect of on-site construction requirements.
本发明公开了一种塔筒用C80混凝土，属于混凝土技术领域，其技术方案要点是，按重量份计，包括以下原料：水泥420‑425份、矿粉55‑63份、粉煤灰55‑65份、硅灰40‑50份、细骨料520‑535份、粗骨料1200‑1240份、外加剂5.8‑6.2份、水135‑140份；所述外加剂包括聚羧酸减水剂、混凝土坍落度保持剂、柠檬酸钠和水，所述聚羧酸减水剂、混凝土坍落度保持剂、柠檬酸钠和水的重量比为（2.0‑2.2）：（3.5‑4.0）：（0.1‑0.5）：（1.4‑1.9），达到混凝土能够在40℃左右的高温环境下进行长远距离运输后，混凝土3小时的坍落度损失为0，混凝土各项性能指标满足现场施工要求的效果。
