In the light of the present international trend of development, it is predicted in this paper that by 2000 A. D., the annual production of concrete in China would be about 500 million cubic metres and that of prestressed concrete would be about 25 million cubic metres. Measures to be taken for the above purpose have been discussed, based upon the existing conditions of China, so that efforts should be directed to increasing of the strength of concrete in engineering structures, developing of light weight aggregates...

In the light of the present international trend of development, it is predicted in this paper that by 2000 A. D., the annual production of concrete in China would be about 500 million cubic metres and that of prestressed concrete would be about 25 million cubic metres. Measures to be taken for the above purpose have been discussed, based upon the existing conditions of China, so that efforts should be directed to increasing of the strength of concrete in engineering structures, developing of light weight aggregates and light weight concrete, producing of concrete of improved properties, extensive use of admixtures, reform of concrete and prestressed concrete technology, improving the quality of concrete as well as increasing the production and types of high strength Prestressing steel, further study on the basic theory of prestressed concrete, increasing the industrialization in the production of prestressed concrete elements, and extending the application of prestressed concrete to various kinds of structures.

结合当前国际发展趋势,本文预测在到达公元2000年时,我国混凝土年用量将达五亿立方米,预应力混凝土年用量将达2,500万立方米。论述了为了达到这个目标,今后应从我国实际出发,在提高工程结构的混凝土强度、发展轻骨料混凝土与轻混凝土、发展改性混凝土、广泛应用外加剂、合理使用掺合料、逐步改造混凝土生产工艺与预应力混凝土基本工艺、提高混凝土质量以及积极生产预应力高强钢材、增添新规格新品种、发展预应力混凝土基本理论与工业化生产程度和扩大应用范围等方面作出努力。

This different acoustic impedance of cement mortars with different mix proportions and water content was analysed according to the acoustical principle. On the basic of this analysis the sound wave method for determining the water content of fresh concrete has been established and a device for testing the water content of cement mortars has been developed. This device is especially suitable for the double mixing process of concrete and may be connected to a microcomputer in order to automatically control the...

本文依据声学理论分析了水泥砂浆的不同配比及不同含水量具有不同的声特性阻抗,在此基础上确定了混凝土含水量的波测方法并研制出水泥砂浆含水量的检测装置,此装置特别适合混凝土二次搅拌工艺,还可与计算机连接实现混凝土生产过程的微机自动控制。

Based on its practical development and production experienced in Fu- zhou city, the strength, workability, and cconemic benefit of commercial conerete under the action of water--reducing admixture are deseribed. The study shows that such concrete is not only in accord with the national standard. but also posse- sses a great potential of development. It is the only way to get the commerciat concrete to help the industrialization of construction.
