钢纤维对C30混凝土受热前、后抗压强度的影响

Effect of the Steel Fiber on the Compression Strength of the C 30 Concrete after and before it's Heated

研究了加入钢纤维对C 30混凝土受热前、后抗压强度的影响。受热前,钢纤维掺量达100 kg/m3时,抗压强度的提高趋缓;受热后,钢纤维掺量达80 kg/m3时,抗压强度的提高趋缓。当钢纤维掺量为80 kg/m3时,受热后的C 30混凝土有较高的抗压强度保持率。

Here is a study of the effect of the steel fiber on the compression strength of the C 30 concrete after and before it is heated.Before subject to heat,when the admixture of steel fiber reaches 100 kg/m^3,the improvement of the compression strength is reduced and after subject to heat when its admixture gets to 80 kg/m^3,the improvement of the compression strength is reduced;and when its admixture arrives at 80 kg/m^3,C 30 concrete has a relatively high retentive ratio of compression strength when subject to heat.
