Abstract

The effects of hot pressing temperature and natural curing time on the properties of the fast-curing cement particle board (CPB)were studied with particles broken from poplar strands of OSB (oriented structural board) factories and 42.5 level silicate as experimental materials and Na2SiO3 as additive .The results were as follows :(1)Hot pressing temperature had no obvious effects on the properties of thick CPB (20 mm), but had obvious effects on modulus of elasticity (MOE) and thickness swelling rate of thin CPB (12 mm)when the hot-pressing temperature was from 85 ℃to 95 ℃.(2)The natural curing time of CPB after hot pressing on the physical and mechanical properties of fast-curing CPB were determined by the hydration of cement .The natural curing time of thick CPB had obvious effects on the properties because the cement well hydrated with high moisture content of thick CPB .The natural curing time of thin CPB had no obvious effects on the properties because the cements didn't well hydrated with low moisture content of thin CPB .[ Ch , 7 tab .10 ref .]
