Submitted: May 12, 2013; Accepted: Jun 18, 2013; Published: Jun 30, 2013 Abstract: This paper investigates on production technology and concrete proportioning methods for lightweight aggregate concrete containing fly ash-metakaolin material. The aggregates were cured in different curing regime such as water curing and hot air oven curing at 100°C. An empirical formula was developed to arrive at...

The paper presents the results of development and implementation technology self-compacting heavy structural concrete concreting with its use largest foundation slab in Belarus (concrete volume ~9100 m3) a high-rise building at facility “Construction multifunctional complex Minsk within boundaries Filimonova Street – Avenue Nezavisimosty Makayonka Street”. research are shown, which ensured pr...

The WebSIM is a technology for interfacing GSM SIMs with the Internet, by implementing a Web server inside a SIM. This paper discusses how this technology can be used for securing services over the Internet and describes several concrete application scenarios.

844 Concrete is one of the most important construction materials. However, it is not so compatible with the demands of sustainable development because manufacturing of cement generates a large amount of carbon dioxide and therefore cement consumption produces a huge carbon footprint. Currently, the cement consumption is generally lowered by adding supplementary cementitious materials to replace...

Self-Compacting Concrete Originally developed in Japan, SCC technology was made possible by the much earlier development of Superplasticisers for concrete. To compare the performance of SCC with Fly Ash 20%, Silica Fume 10%, Rice Husk Ash (5%, 10%, and 15%) as a partial replacement of cement, due to the high increase in construction which has brought a heavy demand for ingredients of concrete s...
