第一冶金建设公司大用高炉重矿渣的工作,做得既轰轰烈烈,有革命劲头,又扎扎实实,有科学求实的态度。他们在工程中推行重矿渣,实际并不一帆风顺,自始至络是有不同认识的。面对这种情况,他们进行了大量的试验工作,多方面进行调查,坚持取得数据,找到根据,使得每一步行动都有实实在在的科学结论作基础。正因为如此,推行重矿渣的工作才取得了使用数量既多,效果又稳妥可靠的重大成绩。在1962年到1964年这三年中间,他们在某地区工程的建设中,连续用了十七万立方米的高炉重矿渣,这个数量同他们同期用的普通碎石量几乎相等。用的范围包括一般混凝土工程、道路工程、铁路工程、抹灰工程及垫层工程。因此节约的投资达230万元、运输力达4160万吨一公里,少用装卸劳动力22万个工日,腾出近50亩农田。从这里,我们可以看得出,第一冶金建设公司在推广应用高炉重矿渣这件工作上,态度很积极,决心很大,把达件工作抓牢了,也抓得彻底,因此见到了效果。看来这是他们把高炉重矿渣推广、用好的一条根本经验。去年年底,他们把近三年来在各种工程中应用重矿渣的经验进行了总结。下面登载的在混凝土工程中应用的经验、在道路工程中应用的经验和开采与加工的经验是其中的三篇。以后本刊将陆续介绍他们在其它方面应用重矿渣的经验。 The first metallurgical construction company used the blast furnace heavy slag to do its work, which was vigorous, revolutionary, solid, and scientific and realistic. They have implemented heavy slag in their projects. They are not always smooth sailing and they have different understandings from beginning to end. Faced with this situation, they conducted a lot of experimental work, conducted investigations in many aspects, insisted on obtaining data, and found foundations, making every walk based on real scientific conclusions. It is precisely because of this that the implementation of heavy slags has achieved significant results with the use of a large number of slags and reliable and reliable results. During the three years from 1962 to 1964, they used 170,000 cubic meters of blast furnace heavy slag in the construction of a certain area, which is almost equal to the amount of common rubble they used in the same period. The scope of use includes general concrete works, road works, railway works, plaster works and cushion works. As a result, a saving of 2.3 million yuan in investment, a transportation capacity of 41.60 million tons and a kilometer, and a minimum of 220,000 man-days of loading and unloading workforce have resulted in nearly 50 acres of farmland. From here, we can see that the first metallurgical construction company has a positive attitude and determination in promoting the application of blast furnace heavy slag. It has firmly grasped the work of the parts and grasped thoroughly, and therefore saw the effect. . It seems that this is a fundamental experience for them to promote and use the blast furnace heavy slag. At the end of last year, they summarized the experience of applying heavy slag in various projects in the past three years. The following experience in the application of concrete engineering, experience in the application of road engineering and experience in mining and processing are among the three. In the future, the journal will introduce their experience in applying heavy slag in other areas.
