The world is now focusing on a sustainable environment and reducing the effects of global warming. One way to achieve such targets properly utilize waste reduce greenhouse CO2 emissions. cement industry responsible for almost 10% emission due high demand in construction industry. ways minimize this effect partial replacement by other materials concrete. Therefore, study, calcium carbide residue...

Self-consolidating concrete (SCC) is a special that highly flow able, non-segregating and self-expanding. Self-compacted poured into the formwork without compaction fills by its own weight. SCC considered to have many advantages. Compared with conventional as improved Construction quality, faster construction activity, lower cost etc. This project was carried out evaluate effects of addition ny...

Given the development of construction industry and design and implementation of high rise buildings with complex sections and various geometrical forms, the use of self-compacting concretes has received the attention of construction engineers and provided great advantages. Due to the increasing air pollution in cities, governments encounter the important issue of repelling the pollutants in whi...

Currently, there are no general provenance management systems or tools available for existing applications. Our goal is to develop provenance technology that is flexible and adaptable to the wide range of requirements of software applications. By consolidating provenance information for a variety of applications, we can provide a uniform environment for querying, sharing, and re-using provenanc...
