High-performance steel slag-based admixture for marine concrete and preparation method of high-performance steel slag-based admixture
The invention discloses a high-performance steel slag-based admixture for marine concrete and a preparation method of the high-performance steel slag-based admixture. The high-performance steel slag-based admixture comprises the following components in parts by weight: 20.0-30.0 parts of steel slag micro powder, 5.0-10.0 parts of an alkaline enhancer, 10.0-20.0 parts of fly ash, 3.0-6.0 parts of desulfurized gypsum, 1.0-2.0 parts of mirabilite and 42.0-52.0 parts of mineral powder, the alkaline reinforcing agent is prepared from the following components in parts by weight: 27 to 45 parts of CaO, 40 to 50 parts of SO3, 1 to 8 parts of SiO2, 2 to 21 parts of Na2O, 0.5 to 3.5 parts of Al2O3, 0.2 to 1 part of MgO and 0.5 to 1.5 parts of Fe2O3. The admixture disclosed by the invention has relatively good early strength performance and excellent seawater erosion resistance, and is beneficial to comprehensive treatment and resource utilization of wastes.
一种海工混凝土用高性能钢渣基掺合料及其制备方法，包括下列重量份数的组分：钢渣微粉20.0‑30.0份，碱性增强剂5.0‑10.0份，粉煤灰10.0‑20.0份，脱硫石膏3.0‑6.0份，芒硝1.0‑2.0份，矿粉42.0‑52.0份；碱性增强剂包括如下重量份数的成分：CaO 27‑45份、SO3 40‑50份、SiO2 1‑8份、Na2O 2‑21份、Al2O3 0.5‑3.5份、MgO 0.2‑1份、Fe2O3 0.5‑1.5份。本发明的掺合料具有较好的早强性能，以及优越的抵抗海水侵蚀的性能，且有利于废弃物综合治理和资源化利用。
