One of the most important causes for deterioration of reinforced concrete structures is corrosion of steel rebar in concrete. Acoustic emission (AE) technique is reported as an effective non-destructive tool for qualitatively identifying the onset of rebar corrosion. The applicability of AE for quantitative assessment of rebar corrosion in concrete is investigated here. Statistical analysis of experimental results under accelerated corrosion confirmed a promising relationship between gravimetrical rebar mass loss and AE measurement. The efficacy of the developed mathematical model was further confirmed under realistic prolonged corrosion exposure. Thus, a new procedure has been developed for quantification of rebar corrosion through experimental verification.Keywords

A feasibility study in which a pultruded fibre reinforced polymer (FRP) plank was used as stay-in-place (SIP) form serving as formwork during wet stage and as reinforcement during hardened stage is presented here. First, the strength and stiffness of the FRP plank serving as formwork for concrete casting under construction stage was verified by sand-filling test. Then shear tests were carried out to develop proper bond technique between FRP and concrete, so that they can perform as composite structural member. Thirdly, static tests on beams were conducted to evaluate the load-carrying capacity and failure modes of the proposed hybrid beam. The overall investigation showed the feasibility of using the FRP plank as a SIP form-work.Keywords

Objective: To generate the energy with the help of conventional and non-conventional sources. Methods: Energy shortage is the major threat for economic development and Rural Electrification can improve the standard of a country. Ministry of New and Renewable Energy (MNRE) gives a report about Uttarakhand and accordingly near about 123 numbers of villages are still not electrified due to shortage of transmission line, this problem can be solved by stand alone system. This paper is a best off grid hybrid system model with the help of HOMER software. Finding: This paper suggests the best Hybrid system for electricity production with the help of conventional and non-Conventional resources to assure the electrical needs of distant village, Dudhali in Uttarakhand state, and estimates the domestic, business, agriculture and small industries demand, and identify the best off-grid alternative. This paper presents issues which disturbing in understanding of the best explanation. Application: One of the most universal concerns of the utilities is to reduce the emission from habitual energy system by using non conventional sources and to decrease the cost of electricity supply to distant areas. Hybrid systems can provide a good solution for such problems because they integrate renewable energy along with the traditional power plants.Keywords
