Microstructural analysis of self-compacting concrete modified with the addition of nanoparticles ... more Microstructural analysis of self-compacting concrete modified with the addition of nanoparticles was carried out. Investigations included SCC concretes modified with different amounts of SiO2, TiO2 and Al2O3 nanoparticle additives and one reference concrete made without nanoparticles. Porosity, maximal pore dimensions, microstructure 3-D models, hardness and elastic modulus were determined. Based on the conducted studies, it can be concluded that the addition of nanoparticles improves the microstructure of self-compacting concrete. It is confirmed both by the results of porosity of the tested samples and by the results of hardness and elastic modulus of the cement matrix of investigated concretes.

At the same time, coal ashes are produced in coal based thermal power plant in large quantity. Fly ash is being used as an alternative material in construction industries while pond ash is disposed-off on huge land areas resulting in environmental pollution through soil, water and air. This research emphases on the study of performance of pond ash as a fine aggregate in self-compacting concrete (SCC). Fine aggregate is substituted by pond ash in percentages of 10, 15, 20, 25, 30. The fresh state properties of SCC like flowability, passing ability of all mixes have been checked by conducting inverted slump cone and L-box according to IS code of practice. The cost analysis of SCC has been conducted to establish the relative cost savings. From the experimental investigation, cost analysis and life cycle assessment, it is concluded that SCC with 20% fine aggregate replaced by pond ash can be economical and environment friendly self-compacting concrete.

In spite of the claim by central and state government that 80% of the rural population is facilitated by the electricity in India, still large portions is either facing a severe shortage or are not connected to grid system so far. The conventional energy sources are over stressed and the use of renewable energy sources is becoming technically and economically feasible due to advancement in technology. These renewable energy sources such as wind, solar and bio mass are creating an opportunity to develop an energy system, exclusively for a village to achieve the energy security. This paper presents a feasibility study of a village for energy security through the wind energy. A wind energy generation system is proposed which will address the minimum energy needs including for household and street-lighting in a village. The life cycle cost analysis of a proposed wind energy generation system for a village is done. The unit cost of electricity is obtained for four phases in analysis period of 20 years, and it is found that the same tunes with the existing ones. A sensitivity analysis is also carried out for different rate of interest and different plant load factors.
