“…In a simulation conducted by Alahabad et al, it was discovered that native materials have greater thermal properties than typical building materials (Alhaddad and Jun, 2013). Mud concrete (Udawattha et al, 2017;Galabada, 2016;Galabada et al, 2020a) and mud concrete reinforced with coir (Galabada et al, 2020b) also have been identified as thermally comfortable construction material in outdoor construction and indoor construction as well.…”

New building materials and technologies that provide thermal comfort are expected to gain popularity in the recent past. Hence, efforts to incorporate new building materials are needed to protect populations from the threats of thermal stress that cause an increase in temperatures due to climate change. The earth is identified as the most effective building material to improve the thermal comfortability inside the building. Among several building construction materials, the flooring material provides a more effective role with respect to thermal comfort in a building. This paper presents the evaluation and comparison work carried out to investigate the thermal performance and user perception of newly invented soil based flooring material with other common floorings in Sri Lanka. Temperature measurements were taken on the top surface of flooring materials and were compared the surface temperature of each other and indoor air temperature. User perception was taken through a questionnaire survey by involving hundred and twenty numbers of responses. The results reveal that the soil floor shows a lesser surface temperature at a significant level than the other floorings. Hence, it can be proved that the building construction materials play an important role and earth is one of the most sustainable materials with respect to the indoor thermal comfortability thus, end-user.

New building materials and technologies that provide thermal comfort are expected to gain popularity in the recent past. Hence, efforts to incorporate new building material solutions are needed to protect potential populations from the threats of thermal stress that cause an increase in temperatures due to climate change.

“…The natural fibres are progressively utilized as a reinforcement material due to their important properties like low density, good thermal insulation properties, good mechanical properties, and low price, etc. [11], [12]. Several types of natural fibres such as kenaf, jute, sisal, flax, and hemp with thermoplastics like polypropylene and polyethylene were studied to manufacture composites as substitutes for conventional synthetic fibres like glass fibres and aramid [13], [14].…”

Waste polyethylene creates serious environmental and social problems in Sri Lanka. The amount of waste polyethylene increases daily, further aggravating environmental and social issues. Finding out the most suitable solution for this is a vital requirement. This research focuses on investigating the possibilities to convert this waste polyethylene as a sustainable construction material by combining it with readily available coconut fibre. A preliminary investigation was carried out on thermoplastic/coconut fiber composites to evaluate their suitability in the construction industry. Composite sheets, 2.5 mm and 3.2 mm thick, were developed by varying coir fibre weight with a suitable polymer matrix using a hot press machine. In this step, mechanical properties of the composite material were measured through tensile and bending tests. The tests were carried out complying with ASTM D3039 and ASTM D790, respectively. The surface morphology of coir fiber and the fractured surface of failure material were investigated through Scanning Electron Microscopy (SEM). Maximum tensile strength was observed as 6.75 N/mm 2 when the coir wt. fraction is inbetween 20-30% by total weight. The maximum bending strength was 29.85 N/mm 2 when the coir fraction is almost 25% by total weight. The corresponding mechanical properties are compared with the available materials in the industry.
