Abstract: Based on the side pressure and buoyancy produced during consructing and shaking concrete, the characteristic and effect factors about the above were discussed in this paper. The site-in-tests about side pressure and buoyancy of mould on the void concrete plates have been made. The test results were compared with the crurent formulas, and wene in agreement with the theory values.

Key words: void concrete plate, mould, side pressure, buoyancy
