Cost optimization of highway, urban and rural facility using sustainable material

In this paper, an experiment of replacement of sand with quarry dust for compressive strength, workability of concrete and cost comparison is done for cost-effectiveness in construction. In this study, there are three basic mix design considered (M20, M30, M40) and partially replacement with 20,50,80 and 100 percentage of quarry dust. It is very beneficial and economical for the replacement of natural sand with quarry dust. In this study, it was observed that when Sand is replaced by Dust the compressive strength was found to be increased. The cost of construction is also reduced by a reasonable percentage.

Awareness level of beneficiaries with respect to the concepts and services of Sanjeevini – A study of Mysuru District

The National Rural Livelihoods Mission (NRLM - Sanjeevini) – Aajeevika was launched on 3rd June 2011. The Mission has the mandate to reach out about 100 million rural poor households in 2.5 lakh Gram Panchayats across the country. The program is being implemented in Karnataka state and Mysore district is one of the five National Rural Livelihood Project areas. Facilitating sustainable livelihood opportunities and encouraging them to come out of poverty is the focus. The study based on primary data collected from four blocks of Mysore district. The multistage sampling frame used to gather the data from beneficiaries. The study consists of 400 beneficiaries, data collected during 2017-18. It was found in the study that out of 400 respondents only 116 respondents were aware of all the benefits available in Sanjeveni programme. The other findings have also inferred that the National Rural Livelihood Mission (Sanjeevini) has not succeeded in generating awareness about the scheme and its benefits among its own Self Help Group members completely. The author further found that Majority of them have been part of the groups for accessing the credit facilities. Making NRLM as the livelihood mission in Karnataka is still a distant dream as the current results highlight only credit and thrift activities. Livelihood promotional activities have required to be paced up.

Prediction of building structure age using machine learning

Determining the service life of building structure is a critical step for the evaluation of maintenance of the building. If the service life of a building is known then proper maintenance and refurbishment steps can be taken. Previous studies focused only on physical obsolescence whereas new concept focused on other new six criteria. The objective of this paper is to use the entire six criteria for the evaluation of obsolescence for the prediction of the age of building a structure using machine learning. A prediction model for predicting age is developed by combining the six obsolescence criteria, absolute weights, diagnostic scores, and machine learning. As obsolescence is predicted using all six criteria, the manual calculation is reduced to provide more accuracy. This prediction model has built using python language, Django as a framework and PyCharm IDE. To make this prediction system more adaptable the website is created and hosted on webhost000.com by combining prediction model and UI of the website which displays the predicted age for respective diagnostic scores. Hence predicting age is useful for taking actions to prevent future degradation.

Experimental study: Alccofine as strength enhancer for geopolymer concrete

Concrete is the most consumptive material after water in the world because of its strength and durability. But the production of cement depends on natural resources and emits a huge amount of carbon dioxide into the atmosphere. For the sustainable environment and to reduce the global warming caused by the carbon dioxide emitted by the cement industry new substitutes which are eco-friendly is the need of the hour. Geopolymer concrete also is known as green concrete or cementless concrete produced by 100% replacement of cement with the waste product obtained from the industries. Geopolymer concrete uses fly ash, slag, and rice husk as a binder which is a substitute for conventional concrete. In present work, the different trail mixtures with variation in Alccofine were prepared to check the workability, compressive strength and permeability of Geopolymer concrete. Variation in content of Alccofine is done as 0%, 10%, 20%, 25% and 30%. As arccosine is an admixture which is micro-fine in its structure, so it may affect the fresh and hardened properties of Geopolymer concrete. In the study, results show that with increase in content of Alccofine up to 25% the significant increase in the compressive strength of concrete can be gained.

Potential of polythene usage in concrete

We as humans are living on the verge of declination because of the excess usage of plastics in our daily life. The construction world keeps on working in innovate ways in order to reduce the work load of the construction units. Plastics, a very important material that was being invented but this has to lead us to many problems like disposal, recycling, etc. the safe treatment of such thing or material is a great challenge to humans and its safe disposal is very challenging. Since this plastic led to a different type of pollution and these problems can be reduced by the usage of plastics in construction. Plastics have the potential to improve the properties of concrete like compressive strength, tensile strength, etc.

Experimental and analytical study on flexural behaviour of reinforced concrete hollow beams

This paper presents details of the studies carried out on flexural behavior of Hollow Core RC Beams with different core depths. As concrete is weak in tension, steel reinforcements are provided in this zone. The concrete is below the neutral axis act as a stress transfer medium between the compression and tension zone. However, in RC beams strength of concrete lying in and near the neutral axis is not fully utilized. So this un-utilized concrete is removed by replacing with any lightweight material. The experimental program consists of casting and testing of RC beams of size 100mm X200mmX2200mm with a hollow core in different diameter of PVC pipes like 12mm, 20mm, 30mm, 50mm from the top near Neutral axis. To study the flexural behavior, all beams are tested by two-point loading. The performance of Hollow Core Beams under flexure by using an analytical method (ANSYS) as well as Experimental method. It shows Ultimate cracking load is more for hollow sections when compared with Solid Beam.
