Abstract

Purpose

The purpose of this paper is to investigate the fracture properties of hybrid woven bamboo (WB)/woven e-glass (EG) fiber composites with various layer arrangements. This paper utilized a specific type of bamboo species named Gigantochloa Scortechinii (Buluh Semantan).

Design/methodology/approach

In these experiments, unsaturated polyester, woven EG and WB fibers were prepared through the hand lay-up technique. The composite bamboo strips were prepared in 1.5 mm thickness. The strips are woven to make a single layer. The layer was then laminated into several thicknesses. The specimens were then characterized using compact tension fracture tests.

Findings

The fracture toughness of 12–14 MPa was obtained. These findings suggest that this hybrid bamboo composite provides superior fracture strength that is equivalent with steel alloy and is extremely a good alternative for reinforcing fibers to combat fracture failures of materials and structures.

Originality/value

In this paper, experimental determination of newly developed composite made of WB and woven EG is presented.

Abstract

Purpose

Tropical buildings are subjected to many militating elements of climate, prominent amongst which are sunlight and rainfall. However, the geographic area in which the study was conducted has an additional influence from the Atlantic Ocean, which is just a few meters away from the buildings. The sea breeze is laden with high salt content that has adverse effects upon and reactions with the materials used for building finishes. In most cases, the outer skin/external surface of a building does not have any protection, due to its function as the protective layer. However, the influence of prevailing saline air in the present case differs from one part of the study location to another due to distance. The paper aims to discuss these issues.

Design/methodology/approach

The study considered two areas of the city, referred to as zones A and B, using a survey approach to obtain data for empirical analysis. Various correlations were evaluated and regression analysis was carried out on the survey findings. The mean behaviour of each zone was determined using the F-value of the results to qualify the performance of paint in service at each location. Data obtained during the study were evaluated using SPSS version 15.0 software. Data were also obtained from architects practicing in Lagos using a structured interview.

Findings

The results demonstrated that degradation of paint set in faster and repainting was required earlier in Zone A than was the case in Zone B, due to more aggressive impact of the saline air. The established research findings that stipulate five to seven years for maintenance of paint were found not to hold good in areas subjected to saline air.

Practical implications

The research was geared towards establishing the appropriate use of paint in saline-laden environments as compared to its use in other parts of a tropical region. Specifiers/architects, developers and property owners may understand better the implications of their choice. Manufacturers should endeavour to develop paint that will retard the deleterious effects of saline air.

Originality/value

This study is the first attempt to investigate analytically the impact of saline air on the maintenance requirements of painted structures in the tropical regions.

Abstract

Purpose

Painting of buildings predates civilization. The primary purpose was to add beauty or aesthetics to the built environment. It was also to showcase the level of civilization, taste and fashion drive of the people. However, modern findings have proved that paint (when applied as a finishing coat on buildings) can elongate the service life of such buildings due to some characteristic properties it contains and modern additives that are included at production stage. This paper aims to examine some of the properties inherent in paint through which resistance to failure and better performance is enhanced, aesthetics is maintained and maintenance is reduced. It also examines whether these qualities subsist in all environments. Particular attention is given to its resistance to the impact of saline air when used around the Atlantic Ocean.

Design/methodology/approach

The research adopted a qualitative and quantitative approach with empirical analysis in examining the performance of paint used in salt laden environment.

Findings

It shows that paint used in an environment where saline air and salt is prevalent begins to deteriorate after two years and requires repainting as against the established norm of five to seven years (5‐7) in areas that are not exposed to saline air. The impact of saline air is significant at p<0.01.

Practical Implication

Maximum life span of current paint products in the area is determined to provide adequate information for the preparation of maintenance schedule for painted exterior. Paint with higher resistance to salt attack is required to enhance the longevity of painted exterior in areas at close proximity to sources of salt. Specifying current available paint for exterior finish will be uneconomical and non‐compatible with the principle of sustainability.

Originality/value

The authors made a fresh attempt at investigating the life's span of paint used as exterior finish in salt laden area around the Atlantic Ocean due to the peculiarity of the stresses of the tropical region on external finishes. It also compared the result with existing researches. Differences in paint performance are established.

Abstract

Purpose

This paper aims to improve the understanding of the institutional pressures that shape the intention to adopt waqf accounting and reporting. The study seeks to answer two research questions as follows: what are the challenges in the adoption of waqf accounting and reporting in waqf institutions; and how do institutional pressures influence the adoption of waqf reporting in Malaysia. Drawing on the work of DiMaggio and Powell and Scott of institutional theory, this paper provides empirical evidence of institutional pressures on the adoption of waqf reporting in Malaysia and the challenges faced in adopting waqf accounting and reporting.

Design/methodology/approach

This study uses qualitative research method with an explanatory case study approach. Data are collected through semi-structured interviews with the accountants of State Islamic Religious Council and Customs of Terengganu, an informal conversation with the Deputy Director of Accountant Generals Department of Malaysia and document reviews, mainly the Malaysian Accounting Standard Board Research paper.

Findings

The findings show that coercive pressure such as government regulation contributes to challenges in the adoption of waqf accounting and reporting. Normative pressures contribute to challenges in formulating standardised waqf accounting and reporting, whereas mimetic pressure contributes to challenges in the comparability of the waqf accounting and reporting among the state Islamic religious councils in Malaysia. In the efforts towards the standardisation of waqf accounting and reporting practice, a similarity of the process of the standard implementation or the institutional isomorphism of the State Islamic Religious Council in Terengganu is strongly influenced from the result of the mandate of its Board members and Fatwa council members (coercive isomorphism and religion logic) and minor influence from the normative isomorphism (the result of the participants’ education and profession) as well as the result of imitating other State of Islamic Religious Councils (SIRCs) because of the ambiguity of the process or certain practice.

Research limitations/implications

The study contributes to the knowledge by extending institutional theory and the possible role of religion logic in Islamic perspective to organisational behaviour and accounting development in SIRCs. This study is limited to the understanding of the challenges in the adoption of waqf accounting and reporting but could also be applicable to the adoption of other accounting standards or regulations.

Practical implications

This paper offers key implications for research, in improving the understanding of contextual factors and decision to adopt waqf accounting and reporting. The standard setter needs to be aware of the influence of contextual factors that shape decision towards standardisation of accounting and reporting for waqf.

Originality/value

The interplay of institutional pressures and implications of religion logic provides an interesting approach to understanding the waqf institutions’ intention to adopt accounting and reporting for waqf.
