Strong explosion-proof high-fire-resistance UHPC as well as preparation method and application thereof
The invention belongs to the technical field of concrete, and particularly relates to strong-explosion-proof high-fire-resistance UHPC as well as a preparation method and application of the strong-explosion-proof high-fire-resistance UHPC. The UHPC comprises the following components: cement, an active admixture, aggregate, a water-based plasticizer, steel slag powder, sintered bauxite and an admixture, wherein the admixture comprises organic fibers, and the organic fibers comprise one or more of aramid chopped fibers, polyamide fibers, polypropylene fibers and polypropylene short fibers; and the admixture further comprises stainless steel fibers or steel fibers. The ultimate fire-resistant temperature is increased to 1100 DEG C or above, a standard temperature rise curve reaches 3 hours, burst does not occur, the defect that existing UHPC is poor in burst resistance in a fire disaster is overcome, the related requirements of public facility fire protection are completely met, the compressive strength is not less than 100 MPA, the breaking strength is not less than 10 MPA, and the application range of the UHPC is widened. The UHPC can be applied to constructional engineering of housing buildings, public places, underground traffic and the like.
本发明属于混凝土的技术领域，具体涉及一种强防爆高耐火的UHPC及其制备方法和应用。所述UHPC的组成成分包括水泥、活性掺合料、骨料、水性塑化剂、钢渣粉、烧结铝矾土以及外掺剂；所述外掺剂包括有机纤维，所述有机纤维包括芳纶短切纤维、聚酰胺纤维、聚丙烯纤维、聚丙烯短纤维的一种或以上；还包括的不锈钢纤维或者钢纤维。所述耐火极限温度提高至1100℃或以上，标准升温曲线达到3小时，且不发生爆裂，解决了现有UHPC在火灾中防爆裂性能较差的缺陷，完全符合公共设施消防相关要求，其抗压强度不小于100MPA，抗折强度不小于10MPA，拓宽了UHPC的使用场所，可将其应用于住房建筑、公共场所、地下交通等的建筑工程。
