考虑初始缺陷影响的混凝土受压特性试验研究

在WAW-E2000电液伺服万能试验机上,对掺入4种不同含量引气剂的混凝土试件进行单轴压缩试验,分析了混凝土试件的抗压强度、弹性模量、极限抗压应变和损伤特性的变化规律。结果表明:随着掺入引气剂含量的增加,混凝土的抗压强度、弹性模量和极限抗压应变均逐渐减小,而初始损伤的程度随之增加。

Experiment study on compressive prosperities of concrete under different initial defections

Under the background of science and technology development and innovation in the new period, it is the objective requirement to deepen the industry-university-research cooperation and collaborative innovation. However, there is insufficiency in China's universities and colleges carrying out the integration of the value orientation, evaluation mechanism, technology transfer, profit distribution, and policy support and so on. Therefore, to further strengthen the industry-university-research cooperation and collaborative innovation and promote the development of science and technology innovation, the universities and colleges in China should increase their science and technology innovation, improve economic and social development, strengthen personnel training and the connotation of teachers' team construction, set up a cooperative and innovative research and development mechanism of industrial technology, and the government should optimize its policy support, etc.
