Lower-income groups in India faces issues such as low living standards, poverty, and a housing shortage. The high cost of obtaining good quality residential houses for people living in slum areas is a major impediment. As a result, to improve their quality of life, an environmentally sustainable method of precast ferrocement can be used, as it has the potential to eliminate this cost barrier. The primary goal of this study is to examine the parameters of precast ferrocement wall panels in terms of economic approach, construction time, and sustainability. The current work compares precast ferrocement structures to traditional structures using a case study of a small ferrocement farmhouse structure with precast & cast in situ types. When ferrocement structures were compared to similar load-bearing and RCC structures, it was discovered that ferrocement structures are more sustainable, time and cost-effective. This research paper also includes quality control parameters for precast ferrocement technology. Keywords: Ferrocement, precast ferrocement wall panels, quality, sustainability, cost effective. 1 Introduction Ferro-cement, also known as Ferrocement, was invented in 1848 by a Frenchman named Joseph Louis. Ferro- cement is a type of thin reinforced concrete that is made up of a large number of small diameter wire meshes that are distributed uniformly throughout the cross section and cement mortar. It is a highly versatile material with a wide range of engineering properties including flexural strength, toughness, fatigue resistance, impact resistance, and crack resistance. It is suitable for precast structural components such as walls, floors, roofs, beams, slabs, water and soil retaining structures, as well as repair work. It can be fabricated into any desired shape or structural configuration that standard masonry, RCC, or steel cannot. It is a low-carbon footprint, sustainable construction material that emits less carbon than standard reinforced concrete masonry. For developing countries with a high demand for housing, ferrocement can be a cost-effective alternative to traditional construction materials. The most innovative invention in the concrete family and composite materials is ferrocement, which can conserve resources, save energy, protect the environment, and reduce human efforts. The most innovative invention in the concrete family and composite materials is ferrocement, which can conserve resources, save energy, protect the environment, and reduce human efforts. The modern ferrocement system for green housing has demonstrated high standards of energy efficiency in housing construction. The ferrocement technique can create extremely energy-efficient homes. It is seen that with thermal insulation installed as part of the construction panels, high levels of thermal performance are achieved, resulting in a reduction in CO2 emissions (Wail N Al Rifaie 2019). In developing countries where there is a high demand for housing, ferrocement can be an effective and low-cost alternative construction material. Ferrocement is long-lasting and cost-effective due to locally available materials and the availability of cheap labor in developing countries. The primary goal of this research is to propose a low-cost house using ferrocement technology, which will reduce the cost of housing projects to the point where they are affordable to people living in slums and will aid in the removal of slum areas from urban development. This research paper also includes quality control parameters. 2 Literature Review According to Patil, Joshi, and Purandare (2020), Ferrocement-Light Gauge Steel composite construction is a lightweight, seismically advantageous, sustainable, and cost effective alternative to RCC buildings. According to the study, the novel composite form results in a 50 % to 60 % reduction in dead weight, 30 % to 35 % reduction in cement quantity, 50 % to 55 % reduction in curing water quantity,50 % to 60 % reduction in chemically bound water quantity, and 25% to 30 % reduction in CO 2 emissions According to Nandakumar, K.Revathi, and M.P.Revathi (2019), Ferrocement Encased Brick Column has consistently higher compressive strength than the brick column without Ferrocement, and thus Ferrocement encasement improves the compressive strength of brick column.
