试验结果表明：粉煤灰单掺会降低再生骨料混凝土的弹性模量，粉煤灰与矿渣双掺对弹性模量的影响随两者组合比例不同而有显著差异。
The experiment results show that that the elastic modulus is reduced when fly ash only was added to RAC and present a significant difference with the rate of fly ash and slag content.
试验还表明，当混凝土强度达到受冻临界强度后，随着负温值的增大其强度缓慢增长，弹性模量也有缓慢增长。
The experiment also shows that after the concrete strength reach the frost-resisting critical strength, its strength and elasticity module will increase slowly with the decrease of the temperature.
