| 根据其组成和热处理方式的不同，这种混凝土的抗压强度可以达到200MPa至800MPa;抗拉强度可以达到20MPa至50MPa;弹性模量为40Gpa至60Gpa;断裂韧性高达40000J/m2，是普通混凝土的250倍，可与金属铝媲美;氯离子渗透性是高强混凝土的1/25，抗渗透能力极强;300次快速冻融循环后，试样未受损，耐久性因子高达100%;预应力活性粉末混凝土梁的抗弯强度蠕动泵 保定建筑设计 保定网站建设 保定网站制作 保定网络公司 保定办公家具 保定轻钢别墅 v与其自重之比接近于钢梁。 According to its composition and heat treatment method, the compressive strength of the concrete can 0 Gpa to 60 Gpa, the fracture toughness is up to 40 0J/m2, which is 250 times as high as that of ordinary concrete and can be comparable to that of aluminium metal; the chloride ion permeability is 1/25 of high strength concrete, and the permeability is very strong after 300 rapid freeze-thaw cycles. The specimens are not damaged and the durability factor is as high as 100%. The ratio of flexural strength to self-weight of the pre-stressed RPC beams is close to that of steel beams |
