“…Similar studies have equally affirmed that building materials take up to 70-75 per cent of the total cost of a standard residential development in Nigeria [22,20]. Of this percentage, walling materials reportedly accounts for more than 15% of the total building cost [23].…”

This study analyzed the cost of production and construction of 225mm hollow sandcrete blocks and hydraform interlocking bricks and walls to compare the findings of the results. The study was conducted in Auchi, Estako West Local Government Area of Edo State, Nigeria. The study compared the construction of two models of 225mm hollow sandcrete blocks and hydraform interlocking bricks, materials employed for wall construction for the study are; clay, cement, sand, water and mould. The result of the study indicates that unit cost of 225mm hollow sandcrete block and hydraform interlocking bricks are ₦168.57 and ₦57.85 respectively. While the cost per square metre of 225mm hollow sandcrete block wall and hydraform interlocking brick wall are ₦3,199.40 and ₦3,079.52 respectively. The study also revealed that it is more costly to apply finishes to sandcrete block wall when compared with hydraform interlocking brick wall. Sandcrete block wall requires rendering or plastering to both faces of the walls, while hyraform interlocking wall requires rendering of not more than 300mm girth to vertical external corners of the brick wall. The study, therefore, recommends the use of hydraform interlocking bricks for low-cost housing to reduce the housing deficit in Nigeria.

“…In relation to material conservation, Mud Concrete Block (MCB) invented by the University of Moratuwa is a novel experience today in combining ancient technology with the modern [6]. Issues related to modern technology that needed to predict towards MCB were non-sustainability and higher cost [7][8][9]. Therefore, the invention of MCB has become a major companion in answering these two issues due to the facts that it is sustainable in the sense that it gains no harm to the environment and it is abundantly available [10].…”

“…Therefore, the invention of MCB has become a major companion in answering these two issues due to the facts that it is sustainable in the sense that it gains no harm to the environment and it is abundantly available [10]. Apart from that, MCB has 92% of reusability and concrete has only 70% [7]. This supports to reduce even waste generation due to the demolition of buildings.…”

Cement is one of the key stabilizers for earth constructions since Roman civilization. The invention of cement was one step in the human civilization. However, cement has many issues especially when it comes to the environmental conservation. The production of cement creates a lot of carbon dioxide and destroys the natural setting to some extent due to the high consumption of clay and lime. Therefore, this study was conducted to alter the cement in mud concrete block. The study started with an inventory of alternative stabilizers that can be found in nature as well as in the human production. And then, the chemical patterns of those stabilizers were carefully identified to alter the typical Portland cement. Several mix proportions were tested and developed to alter the cement and found that the following materials can be developed to alter cement. A natural stabilizer such as tree resins, latex rubber stabilizer, waste ash, rice husk ash and many other ashes can be developed to chemically stabilize the earth blocks. However, out of the invented stabilizers, fly ash and rice husk ash have the high potential to replace cement.

“…India is a quickly urbanizing nation confronting advancement challenges related with fast development. One of the difficulties for a creating nation like India is urban migration [4], which is additionally exacerbated by restricted assets to meet increasing housing demands [5]. The high level of work migration from country territories to urban areas has added to urban clog, pressure on essential courtesies, for example, water and sanitation, and so forth., and a large portion of all, housing shortages in urban areas over India .…”

Urbanization assumes a pivotal role in the economic development of any country. Housing affordability has been broadly perceived as a fundamental issue in making practical assembled condition particularly with regards to developing world urban communities. As a result, a large number of the least urbanized and least developed Indian nations' will confront serious difficulties in giving moderate housing to the urban tenants. This exploration is done to distinguish conceivable indicators for affordable housing in India, particularly in the urban zones. Likewise, it inspects the present view of housing affordability in outlying regions through the improvement of a set of empirical indicators. These indicators are applied to give an incorporated affordability record for each statistical area unit across India.
