A REVIEW OF PROGRESS IN RESEARCH ON FIRE RESISTANCE OF HIGH- STRENGTH AND ULTRA- HIGH- STRENGTH CONCRETES

摘要: 回顾了国内外高强混凝土和超高强混凝土抗火性研究进展,并展望了超高强混凝土(特别是活性粉末混凝土)的下一步研究方向。高强混凝土的高温强度损失与普通混凝土基本类似,但其主要弱点是高温爆裂,可采用聚合物纤维或钢纤维予以抑制。活性粉末混凝土抗火性研究的主要目标应是抑制高温爆裂,减小乃至消除高温爆裂发生的可能性。需要进一步研究宏观断裂性能与微观结构特征,建立活性粉末混凝土抗火性改善的机理,提出确保抗火性的技术途径。Abstract: This paper presents a review of advances in research on fire resistance and high temperature properties of high-strength concrete (HSC) and ultra-high-strength concrete (UHSC).Further research needs in the near future on UHSC,especially on reactive powder concrete (RPC),are also discussed.It is commonly recognized that HSC suffers strength loss in a manner basically similar to that of normal strength concrete.But the main problem of HSC is explosive spalling under high temperature,which can be solved by employing either polymer fiber or steel fiber.The objectives of fire resistance research are to restrain explosive spalling and minimizing spalling probability,so as to ensure satisfactory fire resistance of RPC.It is expected that in-depth research will be carried out on fracture properties,and micro-structure,resulting in establishment of a mechanism for improving fire resistance of RPC as well as technical measures.
