A Study on Self Compacting Concrete using Portland Pozzolana Cement
Abstract: Self-compacting concrete (SCC) is a type of highly flowable concrete that fills each and every corner of congested formwork without the need for mechanical vibration as it is placed by means of its own weight. Generally, the SCC is prepared by using Ordinary Portland Cement (OPC) with mineral and chemical admixtures. Portland Pozzolana Cement (PPC) itself contains some amount of fly ash, thus given the motivation to prepare the SCC …

Dynamic Response of Bridges and its Effect on Soil Medium
Abstract: The analysis of dynamic behaviour of bridge structures that are subjected to moving loads has been one of the research benefits in recent years. Specifically in railway bridges, resonance ensues when the load frequency is equal to a multiple of natural frequency of the structure. Resonance vibrations have been practical in railway bridges, especially subjected to high-speed lines. They are caused primarily because of two reasons: one is the repeated …
