摘要:经济实力的提升为我国进行科研活动提供了资金支持,也给我国各行各业的改革创造了良好的环境。同样,在经济全球化以及科学技术不断提升的今天,越来越多的问题开始涌现出来,并对我国经济的可持续性发展造成了一定的困难。为了更好地体现“科学发展”的主题,具有良好性能的高性能混凝土材料已经逐渐被广泛运用。但是,随着更加复杂的建筑环境的出现,现有的关于高性能混凝土的研究还在继续。本文将以现在广泛运用的高性能混凝土为核心,围绕它所涉及到的原材料以及各材料之间的配比问题进行简单探讨。

Abstract: The enhancement of economic strength for our research activities to provide financial support, but also created a favorable environment for China''s reform from all walks of life. Similarly, in the ever-increasing economic globalization and science and technology today, more and more problems began to emerge, and the sustainability of China''s economic development has caused some difficulties. In order to better reflect the theme of "scientific development", with good performance, high-performance concrete materials has gradually been widely used. However, with the emergence of more complex construction environment, the existing research on high-performance concrete continues. This article will be extensive use of high-performance concrete as the core, around which it is related to raw materials and materials between the ratio for a brief discussion.

Key words: high-performance concrete; raw materials; mix design

高性能混凝土(High performance concrete,简称HPC)是具有优异耐久性的混凝土。其主要特点是高强度、高抗渗性、高工作性能与体积稳定性。高性能混凝土是一种新型高技术混凝土,是在大幅度提高普通混凝土性能的基础上采用现代混凝土技术制作的混凝土。它以耐久性作为设计的主要指标,针对不同用途要求,对耐久性、工作性、适用性、强度稳定性、体积稳定性和经济性等性能重点予以保证。为此,高性能混凝土在配置上的特点是采用低水胶比,选用优质原材料,且必须掺加足够数量的矿物细掺料和高效外加剂。随着我国经济的快速发展以及城市化进程的逐渐推进,现在我国许多中小城市正在开展城市功能重组的一个过程。而在这个过程中城市建设走在前列,为城市发展提供最初的动力。……
