“…Thus, utilization of sustainable materials such as by-products of various agro-industrial activities is being tested for their suitability in the construction sector, as their disposal is quite challenging. The inclusion of microsilica, sugarcane bagasse ash (SBA), bio-briquette ash (BBA), and co-fired blended ash (CBA) in the construction process has improved the performance of construction products [20][21][22][23][24]. Insertion of insulation materials into construction products has also resulted in making structures energy efficient, thermal resistant, cost effective, and reduced dead loads.…”

Under the India “Housing for all” scheme, 20 million urban houses have to be constructed by 2022, which requires the rate of construction to be around 8000 houses/day. Previous results by the team show that present design methods for affordable buildings and structures in India need improvement. The challenges are the disposal of solid waste generated from agro-industrial activities and the energy peak demand in extremely hot and cold seasons. The development of bio-based urban infrastructure which can adapt to the climatic conditions has been proposed. Inclusion of sustainable materials such as agro-industrial by-products and insulation materials has resulted in effective environmental sustainability and climate change adaptability. Precast components are highlighted as a suitable solution for this purpose as well as to fulfil the need of mass housing. India has a lesser record in implementing this prefab technology when compared to a global view. For the first time, a novel and sustainable prefab housing solution is tested for scale-up using industrial waste of co-fired blended ash (CBA) and the results are presented here. A model house of real scale measuring 3 × 3 × 3 m3 was considered as a base case and is compared with 17 other combinations of model house with varying alignment of prefab panels. Comparison was made with commercially available fly ash brick and CBA brick with a conventional roof slab. A simulation study was conducted regarding cost and energy analysis for all the 18 cases. Various brick and panel compositions with CBA for housing were tried and the superior composition was selected. Similarly, 18 model houses of real scale were simulated, with different combinations of walls made of bricks or panels and different building orientations, to check the impact on energy peak cooling and cost. Results show that peak cooling load can be reduced by six times with bio-based prefab panels. Prefab construction can be considered for mass housing ranging above 100 housing units, each consisting of an area of 25 m2.

“…On the other hand, Dove [106] presented maximum compressive and flexural strength of 1.64MPa and 0.95MPa respectively. Sakhare and Ralegaonkar [107] conducted research using bio-briquette ash (BBA) (5-55wt%) for the development of unfired masonry bricks. The findings showed that the density of the samples tended to slowly decrease from 1470kg/m 3 to 1170kg/m 3 as levels of the waste quantity increased.…”

The production process of conventional building materials consumes a high amount of energy which has a negative impact on the environment. The use of locally available materials and upgradation of traditional techniques can be a good option for sustainable development. Consequently, earth has attracted the attention of the researchers as a building construction material for its availability and lower environmental impact. On the other hand, in developing countries waste disposal from the agricultural and industrial sectors raises another serious concern. The scientists have introduced such waste additives into the earth matrix to improve its performance. Therefore, the present paper reviews the state-of-the-art of research on the effects of these various agro and non-agro wastes in the production of unfired earth blocks. This study is divided into three sections: The first section outlines the different types of waste materials and earth blocks considered in the selected papers. The second part deals in depth with the test results of the different properties (density, water absorption, compressive strength, flexural strength and thermal conductivity) of unfired earth blocks containing waste materials. The last section analyses and compares the results with the current earth-building construction standards. The literature survey presents that the waste materials have a clear potential to partly replace earth by complying with certain requirements. Moreover, the application of such wastes for the development of building construction materials provides a solution that decreases energy usage as well as contributes to effective waste management. Future research on establishing guidelines and standards for the development and production of these sustainable unfired earth building materials is recommended.

The present paper focuses on developing a strategy to control the indoor temperature in slum dwellings under redevelopment. The proposed framework aims at improving the building planning and appropriate selection of construction materials along with controlled cost with respect to currently adopted practices. The proposed strategy is elaborated with a case study in Nagpur, India. A single storey, four-room model was planned as per the National Building Code of India. The performance of the model building was evaluated by using energy simulation software TRNSYS. The cellular light-weight bricks used in the construction were made with bio briquette ash (BBA), which is a locally available waste material. Instead of using the conventional reinforced cement concrete (RCC) roof, aluminium and sawdust were suggested as a reflecting-cum-insulating material. To improve the temperature control in model homes, installation of a reflecting-cum-insulating material was conducted, consisting of aluminium and sawdust, over the conventional RCC roof. The model building constructed with these new materials was compared with that built with conventional fly ash bricks and RCC roof. Results show that the proposed model building improved the efficiency of indoor temperature control by 23% and, at the same time, reduced the cost by 13%. The present concept will contribute to the redevelopment of slum dwellings to deliver cost-effective dwelling units that provide occupants with acceptable thermal comfort.
