Abstract:
Aimed at influencing factors of fresh concrete air content in construction of concrete combined with theoretical analysis and orthogonal test, the effects of concrete slump, mixer filling rate and maximal particle size of coarse aggregate on fresh concrete air content are studied in this paper. The test results indicate that under different slumps, the air content slightly decreases as mixer filling rate increasing, when the filling rate is up to 0.32, air content sharply decreases, and under different slumps, the larger the coarse aggregate size is, the more the air content is, and when the slump is oversize or undersize, air content will decrease. 4 tabs, 4 figs, 11 refs.
