Abstract The quasi-static compression tests were conducted on foam concrete specimens with different densities (450 kg/m³, 750 kg/m³, 1 050 kg/m³, and 1 350 kg/m³) and sizes (50 mm×50 mm×50 mm, 100 mm×100 mm×100 mm, 150 mm×150 mm×150 mm and 200 mm×200 mm×200 mm), to investigate the size effect of foam concrete subjected to quasi-static compression. Firstly, by observing the crack propagation in specimens during the test, it is found that the first crack is more likely to appear in the surrounding area from the central area with increasing size of specimens. Secondly, based on the experimental data, the obvious size effect of foam concrete is observed and the effect is more significant with increasing density. Then the relationship between compressive strength, compacting strain, specific energy absorption, and block size are investigated with experimental data. Moreover, three widely applied phenomenological constitutive models, namely Avalle model, Wang mo-del, and Li model, are compared with the experiment data, and it is found that the Wang model is able to provide a good prediction. Therefore, based on the Wang model, damage index and Bažant dimension effect law are introduced to study the relationship between plateau stress and size, and a one-dimensional damage phenomenological constitutive model based on the density and size of foam concrete is established.

Key words： foam concrete size effect compressive strength specific energy absorption phenomenological constitutive model crack propagation
