低强度自流平混凝土的配制与施工

Configuration and Construction of Self-compacting Concrete with Low Strengh

结合住宅承建项目,采用"固定砂石体积含量法"配制低强度自流平混凝土。通过掺入粉煤灰、高效减水剂、增稠剂的技术措施,采用二次投料的搅拌工艺,所配制的混凝土,流动性大,工作性能好,能填充浇筑空间,施工强度小,浇筑成型表观质量合格,在住宅楼板中得到实践应用,适用于大面积楼面和屋面的基层找平和构造层做法,对低碳施工、绿色施工的的发展具有一定的参考意义。

Combined with residential construction project,adopting the fixed sand volume content method chieves configuration low intensity self-leveling concrete.Through taking the technical measures including adding fly ash,efficiency water reducer and thickener,as well as the mixing process of secondary batching,the fluidity of the kind of concrete which is obtained by compound method is large,working performance is good,the kind of concrete can fill pouring space,the construction intensity is low,the surface quality of pouring structure is qualified.The kind of concrete is applied in residential floor it is suitable for base leveling and structural layer method with large area floor and roof.It is significant for low-carbon construction and green construction.
