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 …

Potential of Limestone Powder in the Production of Self Compacting Concrete
Abstract: Self-compacting concrete (SCC) is a cutting-edge building material. It's a smooth, durable concrete that fills the formwork completely. The SCC needs a lot of powder to perform well (mostly cement). However, increasing the cement content is impractical and may result in greater hydration heat and drying shrinkage. This project studies the effect of limestone powder (LSP) on the fresh and hardened appearances of SCC. To evaluate the samples with and …

Assessing the Impact of Soil-Structure Interaction on Seismic Performance of Step Back and Set Back Buildings on Sloping Ground
Abstract: When constructing framed structures on sloping ground, either step back or step back and set back configurations are typically adopted. Due to the varying heights of columns towards the slope and the unsymmetrical nature of these buildings, they are subject to large forces such as shear forces, bending moments, torsional moments, and unequal distribution. In the past, it was common practice to assume that structures were fixed at the base, …

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 …

A Study on OpenMP and Irregular Programming
Abstract: Programmers need better, more reliable techniques to build parallel programs. In the task-parallel programming paradigm, the programmer defines independent pieces of work, called tasks that may run in parallel. Geometric algorithms are wonderful examples for programming, because they are deceptively easy to do with your eyes, yet much harder to implement for a machine. The goal of parallel algorithm design is to develop parallel computational methods that run very fast …
