ISSN 2277-5056 | © 2012 Bonfring Abstract--The use of recycled concrete aggregate is an important issue for preserving the natural resources, protecting the environment, saving of energy and for sustainable development. In this study, a unique simple mixture proportioning method was successfully adopted for developing SCC based on the absolute volume concept, starting with a volume of paste wit...

There is an increasing requirement for the production of concrete globally, due to rapid infrastructure development, leading to shortage in the availability of raw materials, which in turn increase its costs. At the same time, many waste materials are also produced as by-products from various industries and construction sites, the disposal of which cause a major problem. Thus it becomes necessa...

Synopsis: This study presents the experimental results on properties of concrete with replacement of natural aggregate by recycled concrete aggregate (RCA). Experimental data on the creep behavior of concrete mixtures (basic and drying creep) was obtained. The replacement factor of natural aggregate by RCA were 0%, 15%, 30%, 60% and 100%, and the test conditions were 50% RH and 20°C. The result...

Answering natural language questions against structured knowledge bases (KB) has been attracting increasing attention in both IR and NLP communities. The task involves two main challenges: recognizing the questions’ meanings, which are then grounded to a given KB. Targeting simple factoid questions, many existing open domain semantic parsers jointly solve these two subtasks, but are usually exp...
