由中工国际承建的菲律宾阿格诺河综合灌溉项目调蓄水库工程,在大体积混凝土施工中掺加粉煤灰,节约了水泥,减少了水化热,避免了混凝土有害温度裂缝的发生,取得了良好的技术经济效果。该文简要介绍了粉煤灰在大体积混凝土中的应用和粉煤灰混凝土的配制,可供类似工程借鉴参考。 The project of reservoiring at the Agnano River Integrated Irrigation Project in the Philippines contracted by CAMC, which incorporates fly ash in mass concrete construction, saves cement, reduces hydration heat and avoids the occurrence of harmful concrete temperature cracks. Achieved a good technical and economic results. This paper briefly introduces the application of fly ash in mass concrete and the preparation of fly ash concrete, which can be used for reference for similar projects.
