Abstract: A number of researchers today are focusing on ways of utilizing either industrial or agricultural waste as a source of raw materials for production of construction products. Presence of silica in Sugar Cane Bagasse Ash (SCBA) contribute to improved Pozzolanic activity, but the silicate content may vary from ash to ash depending on the burning conditions of bagasse and the properties of soil on which the sugarcane is grown. The main objective of this research was to characterize the compressive strengths of concrete by varying the SCBA and (Ordinary Portland Cement) OPC contents. The SCBA used for this research was sampled from Nzoia Sugar Company (NSC), one of the key players in Kenya’s Sugar Industry. The two variables; cement and SCBA content were applied to establish the concrete’s workability and compression strength at different curing periods (7, 14 and 28 days). Non-probability technique of sampling, specifically purposive sampling was applied in selecting the units that was included in all the samples. The research concluded that SCBA grain size of < 0.075mm and optimum SCBA content of 10% would provide the highest workability and compressive strength in SCBA blended concrete.

Abstract: In present study, Multistoried Framed Structure has been analyzed for different parameters of seismic forces and results so obtained have been compared to understand the effect of seismic forces under static and dynamic analysis. The variousdesign parameters such as beam moments, and storey drift have been evaluated for both static and dynamic analysis.
In this work Multistory Rigid Jointed Steel Framed Regular Building Modal has been analyzed by static, dynamic and pushover procedures. The post processing results obtained are compared to get some important concluding remarks. This study will emphasize on the requirement of non-linear analysis procedures with the existing linear analysis procedures provided by various codal provisions. Present study will help in evaluating the difference in various parameters during elastic (conventional) and inelastic (pushover) analysis.

Abstract:Honing is an internal cutting technique that uses abrasives on a rotating tool to produce extremely accurate holes that require a very smooth finish. Similar to lapping where abrasive sticks are mounted in a rotating tool. Auto sizing means inspecting the dimension of work piece while machining itself. It avoids unnecessary time and manpower used in inspection process. It helps in getting high productivity.In this project work, an attempt has been made to build an autosizing system using pressure cell and microcontroller. An experiment has been conducted by using two stage air compressor, air gauge, ADC, microcontroller, honing head etc., to study the variations of pressure, voltage verses clearance of work piece and depth micrometer.
