A mini type ceramic sensor was introduced and a wireless monitoring system based on GSM technology was developed for the automatic long range, real time monitoring of the pore water pressure(PWP) within the surface layer of fresh concrete. An initial curing procedure for cementitious materials was proposed and its curing efficiency was studied. Results indicate that proposed initial curing procedures(taking 2kPa of PWP as the threshold of initial curing) can prevent concrete with silica fume from plastic shrinkage cracking under severe evaporation condition(evaporation rate 1.32.6kg/（m2·h-1）) and improve the surface durability of concrete. Fogging is recommended as most effective procedure for initial curing.
