高性能混凝土发泡剂的制备方法研究
|
摘要
为提高发泡剂的性能,分别选用十二烷基硫酸钠(SDS)、α-烯基磺酸钠(AOS)和动物蛋白发泡剂(APFA)为研究对象。先通过正交试验,获得最佳制泡条件;再通过复配试验,获得最佳制备复配发泡剂方案为:SDS与APFA的质量比为0. 67∶1,搅拌温度为45℃,搅拌时间为7 min;进一步将最佳复配发泡剂用于泡沫混凝土。结果表明,SDS-APFA复配发泡剂具有较高的发泡性能,其发泡倍数高达50,1 h泌水量为0. 152 m L。该复配发泡剂用于混凝土使其导热系数明显降低,有效地改善了混凝土的保温性能。
In order to improve the performance of foaming agent,sodium dodecyl sulfate( SDS),alpha olefin sulfonate( AOS) and animal protein foaming agent( APFA) were chosen as the research object.Firstly the best bubble conditions was obtained through orthogonal test,and then through the distribution of test,the best distribution of foaming agent preparation conditions were obtained: SDS and APFA mass ratio was 0. 67 ∶ 1,and mixing temperature was 45 ℃,mixing time was 7 min; furthermore,foam concrete was prepared with the best compound foaming agent. The results show that the SDS-APFA compound foaming agent has better foaming performance,and its foaming multiple is up to 50,and 1 h bleeding volume is 0. 152 m L. The thermal conductivity of concrete decreases with the compound foaming agent and the insulation performance of concrete improves effectively.
