Large volumelow-electric-flux fiber concrete for maritime work, and preparation method thereof
The invention provides a large volume low-electric-flux fiber concrete for maritime work, and a preparation method thereof. The large volume fiber concrete for maritime work comprises, by mass, 8.5-11.5% of cement, 2-4% of coal ash, 2.5-3.5% of mineral powder, 5.0-6.5% of water, 29-33% of sands, 6-13% of medium broken stones, 0.3-0.42% of a water reducing agent, 0.03-0.05% of flexible fibers, andthe balance of small broken stones, and the total mass percentage of all the components is 100%. The method is used for preparing for the large volume fiber concrete for maritime work. The compressivestrength, adiabatic temperature rise and electric flux of the concrete are obviously improved compared with those of common concrete.
本发明提供一种用于海工大体积的低电通量纤维混凝土及其制备方法，所述用于海工大体积纤维混凝土的组分包括：水泥、粉煤灰、矿粉、水、砂、碎石、减水剂和柔性纤维；各组分质量配比为：水泥8.5‑11.5％，粉煤灰2‑4％，矿粉2.5‑3.5％，水5.0‑6.5％，砂29‑33％，中碎石6‑13%，减水剂0.3‑0.42％，柔性纤维0.03%‑0.05%，其余为小碎石，各组分总质量百分比为100％。本发明用于海工大体积纤维混凝土。该混凝土抗压强度、绝热温升、电通量相比普通混凝土有明显的改善。
