混凝土制造作为一门传统工艺,其长期的生产实践使得测试实验室样品成为研发和标准控制系统的基本方法;在整个19世纪和20世纪上半叶的发展过程中,该基本方法与实际混凝土技术的条件及结构性能协调得很好。第二次世界大战后,对于混凝土的新需求给水泥和混凝土工业带来了巨大发展的可能。然而在接下来的几十年中,实际混凝土中的有害反应在许多国家出现,其原因包括试验测试系统仍在使用,却未意识到在实际混凝土中反应发生的速率导致性能发生改变,而这在试验样品中并没有出现。这使得试验的再现性与所寻求的混凝土性能的可预测性不能吻合。最近几年,一些资深科学家已经开始提醒要注意普通的试验测试,因为它们不能很好地模拟实际的混凝土行为。除此之外,在国际研究杂志上也报道了混凝土在微观和宏观结构条件的分形特性。与此同时,随着混沌理论的引入,自然科学的发展已经使得对于波动的研究成为可能,也就是说自然的非线性过程与其视觉分形图案得到了结合。
Concrete manufacturing is a traditional process whose long-term production practices have made testing laboratory samples essential for research and development and standard control systems. Throughout the entire 19th and 20th centuries, this basic approach was compared with actual concrete technology The conditions and structural performance are well coordinated. After World War II, new demands for concrete have brought tremendous growth to the cement and concrete industries. However, in the coming decades, harmful reactions in real concrete appeared in many countries due to the fact that test-and-test systems were still in use but were unaware that the rate of reaction in practical concrete led to a change in performance, which In the test sample does not appear. This does not match the reproducibility of the test with the predictability of the concrete properties sought. In recent years, some senior scientists have begun to remind you to pay attention to the general test of the test, because they can not well simulate the actual concrete behavior. In addition, the fractal properties of concrete under microscopic and macroscopic structural conditions are also reported in international research magazines. At the same time, with the introduction of chaos theory, the development of natural science has made it possible to study the volatility, that is to say, the natural nonlinear process is combined with its visual fractal pattern.
