Abstract

The effects of final treatment techniques on the properties of hot pressing cement particle board (CPB) mat were studied with poplar particles of certain size as raw materials , number 42.5 level common silicate cement as glues and Na2SiO3 as fast curing additives .The results were :1)The direct steam curing after the unloading of hot pressing CPB could greatly accelerate thc hydration of cement .2)The eight hourssteam curing with 80 ℃ temperature and 80 % relative humidity equalled to eight daysnatural curing , which could greatly reduce the production time .3)The offects of steam curing after eight daysnatural curing having no obvious effects on the properties of CPB showed that the hydration of cement mainly completed after eight days natural curing so steam curing could not accelerate the cement hydration because the afterwards hydration was slowly carried on .4) The factors of steam curing were :temperature of 80 ℃, air relative humidity of 80 % and time of 8 , 16 and 24 h .The factors need further optimization .[ Ch , 5 tab.9 ref .]
