一、前言随着砼科学技术的发展和建筑工程的需要,作为砼科学的前沿,高强、高性能砼(包含高强泵送砼)的开发和应用得到了长足的发展。高强、高性能砼的性能优越,带来了明显的经济效益,成为该项技术持续发展的强大动力。但又要看到高强高性能砼的生产受众多因素的影响和约束,只有正视及解决种种不利的因素,才能获

I. Preface With the development of concrete science and technology and the need of building engineering, as the frontier of concrete science, the development and application of high strength and high performance concrete (including high strength pumping concrete) have made great progress. High-strength, high-performance concrete superior performance, has brought significant economic benefits, as the continuous development of the technology a powerful driving force. But also to see the production of high-strength high-performance concrete affected by many factors and constraints, only to face and solve all the negative factors in order to be
