摘要
探讨了高烧矢量（１２．９％）粉煤灰对砼抗冻性能的影响，实验中，粉煤灰砼中粉煤灰的掺量为１２０公斤／立方米，为了进行实验对比，同时也对无粉煤灰的砼试块进行相同的实验，通过测试各试块在实验过程中重量、长度和抗压强度的变化来评价试块的抗冻性能，试块的孔隙率是通过则定烘干的试块在水中的重量变化来确定的，实验结果表明，高烧失量粉煤灰可以用于生产高抗冻性能的砼。
The effect of fly-ash with high percent of los on ignition(12. 8%) on the frost-resistance of concrete was investigated. The durability study was made for fly-ash concrete containing 120kg/m3 of fly-ash concrete. Frost- resistance of concrete was assessed by measuring changes in weihgt,length and compressive strength of concrete cubes. Porosity of concrete cubes was determined by measuring changes in weight of dry specimens in the water. The investigations andresults reported lead to the conclusion that the fly-ash with high percent of loss on ignition can be used saticfactorily for producing concrete of high frost-resistance.
