Experiments were performed at lab scale in order to test the possibility to grow microalgae with CO2 from gaseous effluent of cement industry. Four microalgal species (Dunaliella tertiolecta, Chlorella vulgaris, Thalassiosira weissflogii, and Isochrysis galbana), representing four different phyla were grown with CO2 enriched air or with a mixture of gasses mimicking the composition of a typical...

Greenhouse gas (GHG) benchmarking for allocation serves as rewards for early actions in mitigating GHG emissions by using more advanced technologies. China Hubei launched the carbon emission trading pilot in 2014, with the cement industry represented as a major contributor to the GHG emissions in Hubei. This article is set to establish a general benchmarking framework by describing and calculat...

Organizations that implement strategic energy management programs have the potential to achieve sustained energy savings if the programs are carried out properly. A key opportunity for achieving energy savings that plant managers can take is to determine an appropriate level of energy performance by comparing the plant’s performance with that of similar plants in the same industry. Manufacturin...

Handheld XRF may become a useful and cost-saving tool in the cement industry, especially for measuring raw materials and making quick decisions in the field. Calibration methods are explained and results are presented for a Bruker S1 TURBOSD LE used to measure limestone and related materials used in the cement industry. Results are discussed for measurements of powders, pressed pellets, and unp...

The purpose of this study is to review the technological development policy and options in developing countries with special reference to the cement industry. A review of the international cement market, mathematical models for location and demand forecasting, technology transfer and finally a case study undertaken to determine the various options with emphasis on mixing capacity expansion proj...

today, the cement industry is one of the major air polluting industries in the world. hence, in this study, owing to the importance and role of contaminants from the plant, an appraisal of the emission contributions in addition to other factors have been discussed. there are several reasons behind the importance of modeling air pollutants. first, the assessment of standards for air pollution, a...

In this research, 210 concrete cube specimens (15cm) were made replacing 0, 5, 10, 15, 20, 25, 30, 35, 40, 50, and 60 percent of slag powder from Isfahan Steel Mill for cement. The control specimens were made with 350 kg/m3 cement content and the water cement ratio in all specimens was 0.51. The Slump value and compressive strength of concrete specimens in 7, 28 and 90 days were obtained and th...
