摘要
研究了不同粉煤灰掺量及不同龄期条件下,对混凝土孔隙率及强度的影响规律以及二者之间的关系。结果表明:掺入粉煤灰对混凝土的孔隙率及强度均有较大影响。随龄期增加,粉煤灰混凝土的孔隙率明显降低,强度增加,且后期强度超过普通混凝土。
Under different content of fly ash and different age conditions, both the influence of fly ash to concrete porosity and strength was studied, and the relationship between porosity and strength were studied. Results： indicate that addition of fly ash has great influence to concrete porosity and strength. Porosity of fly ash concrete reduces markedly with age increasing, and strength is not only strengthened but also beyond concrete without fly ash in latter age.
