Moisture profiles in drying concrete

摘要: Synopsis The effects of moisture upon concrete properties and performance are briefly reviewed. A system for nondestructively measuring the development relative humidity water content profiles in a uniaxially drying cube is described. Relative humidities measured with purpose-built, miniature probe. Preliminary results show that surface layers dry rapidly enough to impair curing cover zone protects reinforcing steel. At depths greater than 20 mm was relatively slow. Water indicate more porous underlying concrete. depth, OPC replacement water/binder ratio variations time can be described simple empirical equation incorporates hyperbolic function. dropped faster lower higher level pulverized-fuel ash or ground granulated blastfurnace slag.
