Abstract. The present paper deals with the principles of process technology for concrete-polymer composites, the research and development history of the concrete-polymer composites, the recent trends in the research and development of the concrete-polymer composites and the present status of major standardization work for the concrete-polymer composites, on the basis of comprehensive literature survey. The future trends in the research and development of the concrete-polymer composites are predicted, and sustainable concrete-polymer composites are proposed for the 21st century. 

Principles of Process Technology for Concrete-Polymer Composites... 

Concrete-polymer composites are the materials made by replacing a part or all of the cement hydrate binders of conventional cement mortar or concrete with polymers, and by strengthening the cement hydrate binders with the polymers. The concrete-polymer composites are generally classified into the following three types by the principles of process technology for them ...

These questions touch the fundamentals of model theory, which is based on dimensional analysis. Although they have been used in the field of fluid dynamics and heat transfer for more than a century - cars, aircraft, vessels, and heat exchangers were scaled up according to these principles they have only been applied to a limited extent in most areas of process technology, although stirring technology represents a notable exception. 

Despite the complexity of photosynthesis, many aspects of this life-sustaining process are now understood. Technologies whose use contributed (and continue to contribute) to this research effort include spectroscopy, photochemistry, X-ray crystallography, and radioactive tracers. The principles of these technologies and examples of their use are briefly discussed in Biochemical Methods 13.1. 

One of the areas in separation process technology that seems to hold potential for recovery of dilute species from aqueous mixtures is the use of chemical reactions to form easily separable complexes. Such complexes are separated from the milieu of the original system and subsequently the reactions by which they were formed are reversed. Chapter 15 discusses the principles of processes based on this concept, and it provides guidelines in considering this approach for specific systems.

The engineering principles of MBR technology have been developed to the extent that the process is reliable at a large scale. However, the relatively poor understanding of the biological mechanisms contributing to performance, the... 

Six major process simulators are widely used in the chemical process industries today. These are ASPEN PLUS, BATCH PLUS and HYSYS.Plant (Aspen Technology, Inc.), PRO/n (Simulation Sciences, Inc.), CHEMCAD (ChemStations, Inc.), and SUPERPRO DESIGNER (Intelligen, Inc.). In this book and the associated multimedia CD-ROM, coverage is provided of ASPEN PLUS and HYSYS.Plant, which are the two most widely used process simulators. It should be mentioned that once the principles of process simulation are understood, it is a relatively easy matter to switch from one simulator to another.
