摘要

研究了用克拉斯诺亚尔斯克TPP-2集灰器的4个静电除尘器中的4个馏分（Fr1–Fr4）表示的高钙粉煤灰（HCFA）代替水泥对水泥浆性能的影响。测定了含有100至20%Fr1–Fr4组分的试样的流动性、增稠度和抗压强度参数。提出了Fr3含量为20%、30%至40%的水泥浆的最佳组成。

Effect of Replacing Cement with High-calcium Fly Ash on the Properties of Cementing Slurry

The effect of replacing cement with high-calcium fly ash (HCFA), represented by 4 fractions (Fr1–Fr4) from 4 electrostatic precipitators of the ash collectors at the Krasnoyarsk TPP-2, on the properties of cementing slurry was studied. The parameters of flowability, thickening, and compressive strength of specimens containing Fr1–Fr4 fractions from 100 to 20% were determined. Optimal compositions of cement slurries containing Fr3 fraction from 20, 30 to 40% were proposed.

期刊介绍： The Journal "Ekologia i promyshlennost Rossii" («Ecology and Industry of Russia») is aimed to promote acquaintance of the world scientific and technical public and specialists, interested in the problems of the environment protection, with advanced achievements of the science and engineering practice on securing of stable (self-supporting) evolution within the limits of the United Nations accepted recommendations (RIO 92 and RIO+20). A circle of papers includes basic researches and engineering decisions, analytical and methodical operations, reviews on journal subjects. The journal lays special emphasis on methodical elaborations, analytical investigations in the sphere of creating the ecological culture of the population, to the features of ecological education in higher schools of the country for the sake of actualization in specialists'' consciousness of the scientific necessity to know environmental problems of the modern civilization and paths of their settlement. Original papers and investigations of scientists and specialists on separate themes occupy an independent niche of issues under the «Cover story» heading. The journal task is to promote practical implementation of scientific and engineering decisions in the field of decrease of anthropogenic load on the biosphere and environment protection (open lectures, round tables, discussions and so forth). Ecology and Industry of Russia is an informational reference book about the newest developments of the Russian and foreign scientists and the companies realized in Russia, the CIS and Baltic countries, and far-abroad countries. The journal publishes information reports about holding in Russia and abroad the international, all-Russian and regional congresses, conferences, and symposiums related to the journal subjects.
