2) antifreeze compound for pumping concrete
负温防冻泵送剂
3) subzero high strength pumped concrete
负温高强泵送混凝土
1.
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.
通过对负温高强泵送混凝土的抗冻临界强度的研究 ,得出其早期承受冻结的冻结损伤规律 ,并且对不同程度冻结损伤的混凝土的细观结构进行了研究 ,研究表明 ,表征细观层次气孔的各项参数可以有效地反映出混凝土的损伤状
