本文概括介绍了国内外高强混凝土的研究与应用情况,指出了我国发展高强混凝土两个阶段的不同特点,在肯定高强混凝土的技术经济效益的基础上,又着重指出了高强混凝土目前在力学性能上所存在的缺陷。文章还对混凝土在不同抗压强度下的弹性模量、抗拉强度、抗折强度进行了分析、评述,最后指出高强混凝土的发展,应进一步取得材料与结构性能的一致性,加强对脆性问题的试验研究,并探求改善高强混凝土脆性的技术措施。
This article outlines the research and application of high-strength concrete at home and abroad, and points out the different characteristics of high-strength concrete in the two stages of development in China. Based on the affirmation of the technical and economic benefits of high-strength concrete, it also highlights the mechanical properties of high-strength concrete. There are defects. The paper also analyzed and commented on the elastic modulus, tensile strength and flexural strength of concrete under different compressive strengths. Finally, the development of high-strength concrete should be followed by the consistency of materials and structural performance, and the problem of brittleness should be strengthened. The experimental study, and seek technical measures to improve the brittleness of high-strength concrete.
