- 摘要:
- 本文介绍了天津大港区较大型蓄水池冬季混凝土无缝施工法的施工方案及施工工艺。采取加入UEA混凝土膨胀剂、防冻剂和粉煤灰等外加剂，实行一次性整体浇筑的方法，达到提高混凝土的抗裂防渗性能和早期强度，免遭冻害，提高密实度和强度，改善混凝土的和易性的目的。该工程完工后，经多方检查均未发现裂缝和渗水现象，混凝土质量优良，达到设计要求。而且该混凝土无缝施工方法工艺简便、安全可靠，工期短。
The paper introduced the construction program process of concrete no-seam pouring technique to build a large size reservoir during winter in Dagang district,Tianjin city.By being taken a method of pouring a whole concrete with UEF expansion agent,antifreezer fly ash etc.,the concrete early strength,the properties of crack resistance leak protection can be enhanced;the damage from freezing can be avoided and concrete density,strenth harmony can be improved.The crack leak have been not found;the concrete quality is excellent in accordance with design requirement after the project had been finished tested.The concrete no-seam construction process is simple,safe,reliable and with a short working period.2001,5(5): 30-31 收稿日期：2001-7-7作者简介：程汝滨，助理工程师。现在大港石化公司基建工程部从事工业与民用建筑专业，通讯地址：天津市大港区，邮编：300280。联系电话：022一25921144转2414参考文献：
