High-strength refractory concrete
The invention discloses high-strength refractory concrete, per cubic meter of the high-strength refractory concrete comprises 500-550kg of ordinary silicate, 800-810kg of sand, 880-900kg of volcanic rock, 0.6-3kg of polyamide fiber and 160-170kg of water, the polyamide fiber is coated with a dispersing agent, the weight of the dispersing agent is 100%, and the weight of the dispersing agent is 100%. The dispersing agent is prepared from the following components in percentage by weight: 40 to 50 percent of polyester polyol, 30 to 40 percent of nonionic surfactant and 10 to 30 percent of static electricity preventing agent; the combination rate of the volcanic rocks is 6-8%, the absolute dry density of the volcanic rocks is greater than 2.5 g/cm < 3 >, the water absorption rate of the volcanic rocks is less than 3.0%, the mass per unit volume of the volcanic rocks is greater than 1.25 g/cm < 3 >, the stability of the volcanic rocks is less than 12%, the wear rate of the volcanic rocks is less than 40%, and the 0.08 mm sieve passing rate of the volcanic rocks is less than 1%. The clay content of the volcanic rock is less than 0.25%. The problem that existing high-strength concrete is prone to burst is solved.
本发明公开了一种高强度耐火混凝土，在每立方米的高强度耐火混凝土中，包括500～550kg的普通硅酸盐、800～810kg的砂、880～900kg的火山岩、0.6～3kg的聚酰胺纤维以及160～170kg的水，所述聚酰胺纤维涂敷有分散剂，其中，以所述分散剂的重量为100％计，所述分散剂包括40～50％重量的聚酯多元醇、30～40％重量的非离子表面活性剂、10～30％重量的静电防止剂；所述火山岩的组合率为6～8％、所述火山岩的绝对干燥密度大于2.5g/cm3、所述火山岩的吸水率小于3.0％、所述火山岩的单位容积质量大于1.25g/cm3、所述火山岩的安定性小于12％、所述火山岩的磨损率小于40％、所述火山岩的0.08mm筛通过率小于1％、所述火山岩的黏土含量小于0.25％。本发明解决了现有的高强混凝土存在易爆裂的问题。
