“…To make the calculations, the specific heat of asphalt mixture has been considered constant and equal to 964 J/kgK [24], the specific heat of bitumen equal to 1900 J/kgK [1], and the specific heat of steel as 482 J/kgK [25]. Moreover, considering that there is 5.3% of bitumen in asphalt mixture, the calculated specific heat capacity of the binder (bitumen and fibres) in mixtures with 2%, 4%, 6%, and 8% of fibres, is 1511 J/kgK, 1290 J/kgK, 1147 J/kgK, and 1047 J/kgK, respectively.…”

“…The construction industry utilizes wider range of materials compared to others, mainly for the purposes of structural material, finishes, and services related materials (Ahmed and Sturges, 2015). Gama (2012) observed that global construction activities consume 40% of global energy and 30% of raw materials while being responsible for about 35% of carbon dioxide and 28% of landfill materials as construction waste.…”

Building construction contributes to a substantial consumption of raw materials compared to other sectors in Sri Lanka. Despite the excessive consumption of raw materials, industry is suffering due to low productivity and economic inefficiency. Thus, the circumstance has led to employ alternative building materials to overcome productivity and cost inefficiency with favourable impacts on sustainability. Polymer has become a global phenomenon with increasing demand as sustainable alternative. Polymer facilitates multiple applications in building construction due to its supreme properties and characteristics. Thus, this research focused develop a quantitative model based on factors related to productivity enhancement and cost reduction to measure the applicability of polymer materials in Sri Lankan building construction. A mixed approach consisting of semi structured interviews followed by a questionnaire survey was adapted for conduct this study. 12 experts were selected for the semi structured interviews and 34 respondents participated for the questionnaire survey. The significance of favourable impact to the productivity and cost efficiency of using polymer materials have been identified in the study. The study discussed the applicability of polymer types in building sector in Sri Lanka and derived resulted in a quantitative model to measure applicability of polymer adoption in the terms of productivity and cost related factors. Study concluded that inherent properties of polymers, buildability, ability to prefabricate, life cycle cost, handling would improve the applicability to local context. Further, relationship identified through the regression model would assist practitioners to select polymer materials while enabling researchers to improve the quality of the products.

“…Clay bricks are found to be mass-produced and thoroughly tested modular building components which is affordable in price and readily available across the country. These clay bricks possess fantastic acoustic and thermal properties derived from their relatively high mass [6]. They require comparatively little maintenance and possess high durability and load bearing capacity [7].…”

In Bangladesh, clay bricks are extensively used as building construction material. Rapid urbanization in the country has spurred the brick production of 8.6 billion each year. Larger part of brick fields have been set up illicitly, near human homes, schools, colleges, medicinal services offices, disregarding the current laws in this regard. Top soil of agricultural land is collected for producing bricks. As a result our country is losing hectares of precious topsoil each year. In Bangladesh, around 12,000 brick kilns are in operation. A kiln produces averagely 8,500 bricks using 1,000 cubic feet of topsoil. Tons of forest wood is burned to produce bricks every year. Brick kilns emissions consist of carbon-dioxide (CO2), particulate matter (PM) including black carbon (BC), sulphur-dioxide (SO2), oxides of nitrogen (NOx), and carbon monoxide (CO), thereby causing air pollution. Brick kilns around Dhaka are responsible for up to 58 percent of all the fine-particulate air pollution in the capital. Unabated growth and running of brick kilns reveals the fact that the law enforcement mechanism is not functioning properly. Housing and Building Research Institute (HBRI), has come up with various alternatives of bricks, rarely used in any private or public buildings. This study concentrates on the roles of existing laws to control brick manufacturing and kiln establishment in Bangladesh and also scope of Alternative Bricks (ABs) in Bangladesh.
