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.

In this paper, a microcomputcrized neutron moisture gauge is reported. This gauge consists cf a neutron moisture sensor and instruments. It is developed from the neutron moisture gauge for concrete mixer. Its character is that a TECH-81 single card microcomputer is used to play the role of count, compute and display. Its function has been increased ever the early type of the neutron moisture gauge. It has the function of computing compensated quantity of sand. It can acquire those measured data of several neutron sensors by the multichannel sampling, therefore it can measure moisture values of those sands in several hoppers simultaneously. The precision of the static state calibration curve is 0.24%wt. The error limits of the dynamic state check are <0.509%wt. It has satisfied the demands of the concrete production.

本文报告了一台微机化中子水分计。该计是由混凝土拌合机用中子水分计发展而成的。其特点是采用TECH-81单板机来完成计数、运算和显示的任务。它具有计算补砂量的功能,并能通过多道采样获取几个中子水分传感器的测量数据,所以能同时测量几个料斗内黄砂的水分。静态标定曲线的精度为±0.24%wt,动态考核误差极限<0.5%wt,已能满足混凝土生产的要求。
