Abstract:The effect of dry density, water-cement ratio, the addition of fly ash, and sand content on the porosity and pore distribution of foamed concrete is investigated. Digital microscopy and Image J software are employed to examine the landscape of pores with different sizes. Based on the Balshin empirical formula, a mathematical model is established to quantitatively predict the relationship between the pore structures and the compressive strength of foamed concrete. The results well demonstrate that there is a significant correlation between the modified formula and empirical parameters. © 2018, Editorial Department of Transactions of NUAA. All right reserved.
