The new Concrete Society Publication, Cementitious Materials, CSTR74, covers the effects of cementitious materials blast furnace slag (GGBS), fly ash (FA), limestone fines and silica fume (microsilica) on the properties of concrete. This paper focuses on the effects of silica fume on all the main properties of concrete in the fresh and hardened state as defined in the publication.

This paper presents a logically complete assumption based truth maintenance system (ATMS) that is part of a complex blast furnace computer aided piloting system [ 5 ] . This system is built on an e cient and logically complete propositional constraint solver that has been successfully used for industrial applications in computer aided design.

The present study deals with the utilization of fines generated from comminution process (crushing, grinding and screening) of the Run of Mines into value added products i.e. fluxed iron ore pellets. The study comprises to understand the physical and mechanical behavior of five distinguished chemical compositions of green and dried iron ore pellets with respect to a typical Mini Blast furnace (...

BACKGROUND Noise pollution is currently a major health risk factor for workers in industries. The aim of this study was to investigate noise pollution and implement a control intervention plan for blast furnace in a steel industry. METHODS The measurement of sound pressure level (SPL) along with frequency analysis was done with the sound-level-meter Cell-450. Personal noise exposure was perfo...

Kardas Czestochowa University of Technology, Faculty of Materials Processing Technology And Applied Physics, Czestochowa, Poland The analysis of the eff ect of the qualit y of f errous burden materials on the paramet ers of blast furnac e process is presented in this paper. First, the quantitative and qualitative analysis of ferrous burden materials used in blast furnace process was made. Th...

In steel industry, without consideration of blast furnaces, reheating furnaces are classified the biggest energy consumers. The research of efficient control algorithms permitting less energy consumption has become an important issue for those furnaces. In this paper, a nonlinear Model Predictive Controller (MPC) is designed for a steel slab walking-beam reheating furnace. A numerical nonlinear...
