Abstract:
The use of fly ash in concrete improves several characteristics of conventional cement-based pastes, mortars, and concrete such as reduces heat of hydration, increases strength in long-term and enhances durability. However, types and volume of fly ash affect behavior of resulting pastes, mortars and concrete. In this study, the characteristics of pastes, mortars, and concrete with 20% and 30% binder replacement with a Hongsa fly ash from Laos (FAH3) and two fly ashes from Thailand (FAM and FAB) were studied. Further, mechanical and durability properties of Hongsa fly ash mortars and concrete a

Abstract:
By testing flexural and compressive strength at different ages, the influence of particle size distribution of slag and fly ash on the strength of LCC (low clinker cement) were systematically studied. The SEM (scanning electron microscope) and laser particle size analyzer were used to study the multi-component cementitious and dense-packing effects of LCC. The results show that the strength development of LCC4 with 30% clinker could completely meet the requirements of P.O 42.5R by varying the type, content or fineness of admixtures; based on a higher fly ash and lower clinker dosage, the stren

Abstract:
A method of analyzing the particle size of inorganic dirt in raw wool is described. This method was applied to 25 raw wool samples of different origin, type, fineness, and grease and ash content. The results show that the particle size distribution of inorganic dirt is monomodal and approaches a log-normal model. The distribution parameters such as geometric mean diameter and standard deviation were also evaluated. In all samples, the geometric mean diameter was in the range of 9 to 28 micrometers without any correlation with other raw wool characteristics.

This is an experimental study which explores the physical, mechanical, and economic factors involved in the production of type CEM II A-B/W cement. In this context, 4 cement additives were used in two different dosages (200 and 800 g/t). Class C fly ash was used for composite cement production at ratios of 5%, 20%, and 35%. It was shown that Blaine fineness increases with the increasing fly ash content. The use of fly ash at ratios of 5% and 20% was not found to have any unfavorable effects on the compressive strength at the early days. It is found that the use of additive for improving the ea

Abstract:
The ways of reducing CO2 emissions in the cement industry were analysed for the purposes of implementation of the low carbon development strategy. The optimal solution to this problem is the technologically optimised blended cements with high volume of supplementary cementitious materials of various genesis and fineness. The design of eco-friendly blended cements was achieved by a synergistic combination of the main constituents such as granulated blast furnace slag, superfine zeolite, fly ash and limestone, as well as by optimisation of the their granulometric composition, taking into account

Abstract:
The role coal in power industry is predicted to be increased in future that is caused by its large stocks and depletion of oil and gas fields. Due to production growth, deterioration in mining and geological conditions and broad mechanization of production, the quality characteristics of coals as ash content, particle-size distribution, humidity and sulfur content worsen. Therefore, practically all mined coal requires enriching. The smallgrade and fine concentrates received after enrichment often happen to be unsuitable because of their fineness for further processing or direct use. Therefore

Some of Eskom’s power stations which are equipped with Electrostatic Precipitators (ESP’s) were not designed for this stringent legislation.

Abstract:
The pulverizer plays a pivotal role in coal based thermal power generation. The improper coal fineness or drying reflects a quality-wise deterioration. This results in flame instability, unburnt combustible loss, and a propensity to slagging or clinker formation. Simultaneously, an improper air-coal ratio may result in either the coal pipe choke or the flame impingement, an unbalanced heat release, an excessive FEGT, overheating of the tube metal, etc, resulting on the reduced output and excessive pulverizer rejects. In general, the base capacity of the pulverizer is a function of coal and air
