粉煤灰陶粒混凝土抗冻性能研究

Lytag concrete antifreeze performance study

根据JGJ 51—2002《轻集料混凝土技术规程》,选用品质优良的粉煤灰陶粒,采用合理的配合比,制作性能优越的粉煤灰陶粒混凝土。分别研究不同胶凝材料总量和不同粉煤灰取代率(15%、30%)对粉煤灰陶粒混凝土的抗冻性能的影响。结果显示:随着胶凝材料增大,粉煤灰陶粒混凝土的抗冻性能呈增大趋势;随着粉煤灰取代率的减小,粉煤灰陶粒混凝土的抗冻性能呈减小趋势。

According to ＂Regulations of Technology of Lightweight Aggregate Concrete＂ （JGJ 51--2002 ）, it adopted lytags of good quality and produced the lytag concrete of superior performance in reasonable mixing ratio.Then,it studied the effect of different quantity of gel materials and different replacement ratio of fly ash （ 15% and 30% ） on the frost resistance of lytag concrete.The results reveale that the frost resistence of lytag concrete show a trend of increase with the increase in gel material.The frost resistance of lytag concrete showed a trend of decrease with the decrease in fly ash replacement ratio.
