Assuring the quality of the massive quantities of cement produced worldwide each year is a daunting task. Currently, the cement industry performs extensive physical testing to assess the quality of their product, resulting in large costs for both materials (and their disposal) and labor. One of the major goals of the Virtual Cement and Concrete Testing Laboratory (VCCTL) consortium is to provid...

in this study it has been initiated to find out the credit strength and financial performance of cement industries in bangladesh through investigating the financial report for the period from 2007 to 2011. financial ratios are employed to measure the liquidity (working capital to total assets), profitability (retained earnings to total assets), efficiency (earnings before interest and taxes to ...

This paper analyzes an existing maintenance management system in a cement factory in the Kingdom of Saudi Arabia using a modified questionnaire. The analysis shows that there are strong areas such as predictive maintenance and maintenance automation. Other areas are found weak such as training programs and maintenance reporting. Some areas are found mix between strong and weak such as maintenan...

Several different carbon-capture technologies have been proposed for use in the cement industry. This paper reviews their attributes, the progress that has been made toward their commercialization, and the major challenges facing their retrofitting to existing cement plants. A technology readiness level (TRL) scale for carbon capture in the cement industry is developed. For application at cemen...

whose suggestions got this paper off the ground and gave it direction. The paper has also benefitted from comments from The contributions of innovations, factor endowments and institutions to American industrialisation are examined through analysing the rise of the American portland cement industry. Minerals abundance contributed in multiple ways to the spectacular rise during the 1890s. Howeve...

A distribution of particle sizes or particle size distribution (PSD) is a fundamental characteristic of cement powder. Accurate PSDs are required in computational efforts to model the hydration process and it is an important practical issue for the cement industry. Presently, the only available standard method for measuring the PSD of cement, namely ASTM C115, is limited in scope, with a lower ...

This paper describes the present situation of waste and by-products utilization in cement manufacturing in Japan, introduces Ecocement which is a new cement using municipal waste incinerator ash from household activities as the primary raw material, and discusses the contribution expected of the cement industry in establishing a resource recycling-based society in this country.

BACKGROUND Listeria monocytogenes is of major concern to the food industry in general and the dairy industry in particular. Little is known about incidence of this pathogenic bacterium in dairy products in Iran. METHODS A survey was made from 23 September 2006 to 22 June 2007 for Listeria species in ninety samples of traditional and industrial cheeses, in milk and surface where the cheeses we...

in order to study of deficit irrigation levels on wheat grain yield cultivars based on water productivity indices, an experiment was conducted in a split plot arrangement in randomized complete block design at the field of agricultural and natural resources center of isfahan (kabutarabad research station). three levels of irrigations: 60% of full irrigation (f1) and 80% full irrigation (f2) and...

This study was conducted to isolate an acid-producing, alkaliphilic bacterium to reduce the alkalinity of cement industry waste (cement kiln dust). Gram-positive isolate KG1 grew well at pH values of 6-12, temperatures of 28-50°C, and NaCl concentrations of 0-16% and thus was further screened for its potential to reduce the pH of an alkaline medium. Phenotypic characteristics of the KG1 isolate...
