Influence of industrial waste water in Nagpur area on properties of silica fumed concrete

In today's era of modern construction techniques addition of silica fume in concrete to get high strength and superior performance is normal practice. Although we utilise the waste silica fume in concrete, there are many other waste products, bi-products which needs to be utilized in a scientific manner to prevent the deterioration of the environment. Also, all utilization should be done in ways which are helpful to mankind otherwise they will create more haphazard threats. In this study, the effects of industrial wastewater on silica fumed concrete were experimentally investigated. The main objective of the study was to replace the use of fresh water in casting and curing of concrete structures with industrial wastewater and to analyze the effect on various parameters like Tensile, Compressive and flexural strength, Slump, acid resistivity, corrosion of silica fumed concrete. The silica fume was incorporated in concrete at levels of 5%, 10%, 15%, 20%, 25% & 30% while water-cement ratios were 0.45 to 0.49. All tests were carried out after wet curing of 7,14 & 28 days. Tests results show that though silica fume and industrial wastewater both can be used in high-performance concrete, they should be in proper proportion.

Scaling resistance of silica fumed concrete using industrial waste water

In the modern era of fast construction practices due to the inappropriate use of various suer-plasticisers, admixtures and improper curing methods scaling is one of the rapidly upsurging complications in exposed concrete. This problem can be seen in many structures which had insufficient curing and porous finishing layer. Excessive use of deicing salts, severe exposure of concrete and improper mix design add acute complexities to scaling. Main reason for scaling is porous finishing surface. This problem can be solved by using silica fume as it fills the voids between cement particles. Other reason is cyclic expansion and contraction of entrapped water which not only widens the pores but also leaves behind harmful chemicals in residual form. These chemicals can not reside if concrete already possesses the acidic properties. In this research, we used silica fume as partial replacement of cement and mildly acidic industrial wastewater in concrete. Results show that when silica fume is added by 20% of cement and industrial wastewater is added in same proportion as potable water chloride concentration can be reduced by 35% which can be very useful in preventing the scaling.

Cost analysis of building construction by using autoclaved aerated concrete block (AAC), fly ash brick and clay brick as masonry component

This research work was done to show comparative study residential building while considering dead and live load using AAC block or fly ash and a clay brick for G+5 building was done. The use of AAC blocks offers an innovative solution to the construction industry associated with preserving environmental issues. In this work, also an attempt has been made to calculate bricks and blocks quantity per floor. The G+5 building was designed with the help of Staad pro software and the cost calculation for steel take off, cost of structure etc. was carried out. Autoclave aerated concrete (AAC) block has been found to be economical as a construction material replaced by conventional brick. After designing the structure we are found that if we used AAC block in place of conventional brick we are saving almost around 25.08 % of steel in the overall project.

Review Paper

A review on cost analysis of building construction by using autoclaved aerated concrete block (AAC), fly ash brick and clay brick as masonry component

Burnt clay brick is a predominant construction material used in construction. As we also know that the brick manufacturing process involves CO 2 emissions which leads to produce global warming. Hence to overcome these issues we have to focus on saving our environment. To fulfill this objective, new construction materials can be used for construction. Recently AAC blocks were used commonly for building construction and it is a far better alternative material for construction. Therefore this paper discusses the review of Building Construction by using Autoclaved Aerated Concrete Block (AAC), Fly ash brick and Clay brick as Masonry Component.

Quantitative analysis of potential energy sources

The energy sector is considered to be one of the most important building blocks in the development of our economy as well as a significant index for the growth of humans as a whole. For developing nations like India, there is an increased need for reliable and efficient sources of energy as they are building blocks to a more developed emergent future. In this uncertain time in the global market with reliance on one another for energy, it is vital that we grow and evolve energy so as to be resourceful, productive, cost-efficient and self-sufficient. Energy has many sources-solar, thermal, hydro, wind etc. Each and every source of energy is accompanied by its own constraints. These sources of energy need to be analysed both quantitatively as well as qualitatively so as to choose the most optimal source of energy. These forms of energy can be harnessed effectively to produce energy. The research paper aims at forecasting future energy requirements of different states and the best possible source that meets their transport and cost requirements. Operations research has thus been used to analyse these sources of energy and derive conclusions from available data.

Industrial waste water in silica fumed concrete– A brief study

With a rapid growth in the construction industry, there is an increased demand for concrete for various uses. For concrete mixing and curing potable water is one of the most important ingredients. With increased population and agriculture sector and decreased average annual rainfall, the supply of fresh potable water to the construction industry is on the decline. In many drought-affected areas, water is scarce for even human needs. This may hamper the supply of fresh water to the construction industry. There is dire need to find the alternatives to fresh potable water to sustain the noteworthy growing rate of the construction industry. This paper investigates the effects of industrial wastewater in silica fumed concrete on not only strengths but also on other aspects like abrasion resistance, acid, and alkaline resistance. As silica fume is freely available bi-product in ore production, we normally ground-fill it. Considering the hazards of mixing it with groundwater we decided to use it in concrete as a partial replacement of cement. Also while taking an environmental approach we have to take into consideration the natural environmental conditions for structural strength of concrete. So abrasion resistance and acidic, alkaline resistance was also determined. Overall results show that through the strength of this newly formulated concrete increases, it fails on certain parameters like acid resistance but it certainly has more positive impacts on the environment.
