混凝土的应用与发展 concrete

摘要
高强混凝土作为一种新的建筑材料，以其抗压强度高、抗变形能力强、密度大、孔隙率低的优越性，在高层建筑结构、大跨度桥梁结构以及某些特种结构中得到广泛的应用。本文主要探讨高强混凝土的制作及施工工艺。
对混凝土（高性能混凝土、活性微粉混凝土、低强混凝土、轻质混凝土、钢纤维混凝土、自密实混凝土、智能混凝土等）以及混凝土增强材料(非金属配筋、新型预应力钢棒等）近年的应用与发展，作了一些研究。

The application and development of concrete
Abstract
High-strength concrete as a new building materials, with its high compressive strength, anti-deformation capability, high density and low porosity of the superiority in high-rise building stru- ture, the structure of long-span bridges, as well as some special structure is widely applicated.This article focused on the production of high-strength concrete and construction technology.
Of concrete (high-performance concrete, reactive powder concrete, low-strength concrete, lightweight concrete, steel fiber reinforced concrete, self-compacting concrete, smart concrete, etc.) and concrete reinforcing material (non-metallic reinforcement, a new type of prestressed steel bars, etc.) in recent years application and development, some studies were made.
