This study was conducted to have a detailed analysis of the geotechnical properties of expansive soil and fly ash from Sipat thermal power plant. It reported the findings of laboratory studies on certain common physical and geotechnical properties. The chemical properties and morphology of the black cotton soil (BCS) and fly ash is also determined using scanning electron microscopy and X-ray diffraction test. The geotechnical test includes determining specific gravity, particle size distribution, moisture content, standard proctor test, free swell index, and Atterberg’s limit. The different compositions of expansive soil with fly ash, yellow soil, moorum, and sand are studied. BCS was evaluated with fly ash, fly ash and sand, BCS with yellow soil, and moorum and fly ash. The study also analyzed the details and results of different tests conducted on soil samples. The results showed that strength and fly ash are inversely proportional; as fly ash increases, strength decreases, and vice versa. Fly ash was added from 20 to 80 % by replacing expansive soil by weight. The results indicated that expansive soil can be stabilized by the addition of fly ash to a limit of 10 to 20 %. HIGHLIGHTS The XRD And SEM results shows the mineral present in the FlyAsh and Expansive soil The geotechnical properties of Flyash and expansive soil is determined The OMC increases with decrease in densities The Particle size distribution curve shows the soil is GW soil GRAPHICAL ABSTRACT
Chhattisgarh state is the first in nation to get Central Government approval for Affordable Housing Projects in Chhattisgarh under Pradhan Mantri Awas Yojna (PMAY) launched in June 2015. Under this project, the aim is to build 26,034 houses in 11 cities and towns of Chhattisgarh till 2022 including 12670 houses for Economically Weaker Section (EWS) that includes all households with an annual income of less than Rs. 3 Lakh and 13364 Houses for Lower Income Group (LIG), that includes all households with an annual income of less than Rs. 6 Lakh. Most of the people in urban areas are working either as daily wages or Informal sectors. They are facing financial problems in constructing Puckka house and require financial support for the construction of their house. To full fill their need of house in affordable cost, Affordable Housing in Partnership (AHP) scheme is regarded. Under this scheme, Subsidy by NHB (National Housing Bank) & HUDCO (Housing & Urban Development Corporation) or Financial support by Nationalized Banks, Housing Finance Institutions provides loan to the beneficiary. The impact of the affordable housing, with the initiatives taken by the government is evaluated in this article.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
