| Abstract: | Through the studies to anti-freezing critical strength of subzero high strength pumped concrete, we deduced the freeze-damage law of early age, and, through studies to submicro-construction of damaged concrete, we found the parameters of pore at submicro-construction can reflect the damage status of the concrete effectively. |
