“…The use of EPS as moulds to cast concrete has been in the construction industry for a long time whereby, they are used as prefabricated and in-situ concrete (Martins et al, 2015). Additionally, the usage of EPS mould in this study was its cost-effectiveness in moulding complex concrete forms (Seo & Hong, 2017;Yun et al, 2021). In this experiment, both greased and ungreased EPS designs produced similar results after demoulding.…”

“…EPS moulds were selected because they are frequently employed to create geometrically shaped or complex designs. However, they are often utilized for a single test as they must be torn apart when demoulding the specimen (Mohammadi et al, 2014;Yun et al, 2021). While comparatively weak, they offer insulation and protection from vibration for freshly foamed concrete cubes (Coombes & Naylor, 2011;Coombes et al, 2017).…”

Poor quality habitat profiles of artificial coastal structures for biodiversity growth compared to natural shore have led researchers to utilize ecological engineering principles in creating habitat enhancement models mimicking the natural environment to help improve living conditions for marine organisms. Extensive global trials have been conducted with concrete formulations incorporating eco-friendly materials and recycled resources. However, eco-concrete production for marine environment use is still lacking in Malaysia. The technology involved in casting, moulding, and demoulding remains at the experimental stage, with unreported comparisons of different moulding materials used for casting geometrically complex habitat enhancement models. This study evaluated different casting, moulding, and demoulding techniques using locally produced eco-concrete. The main aim of this study is to determine the effect of different materials including plaster of Paris, drilling wood, expanded polystyrene, rubber foam, and vacuum forming on the mould production time, labour requirements and fabrication factors. Vacuum forming mould is highly preferred for its quick production time, less work, design uniformity, and ability to cast larger habitat enhancement models. However, the demoulding methods require improvements and further experimentation to ensure an easier demoulding process and reusability of the mould for long-term production.

As free-form panel production takes a long time, it extends the construction period and increases construction expenses. This study suggests a method to apply radiant heat to concrete for the purpose of shortening the curing and removal process in free-form panel production. The optimal temperature and time for removal are determined based on the results of constant temperature/humidity curing experiments and quartz tube heater curing experiments. Through an experiment in various time settings, the general time of FCP (Free-form Concrete Panel) production is measured to examine whether the productivity is enhanced. It is expected that findings of this study contribute to shortening the construction period and reducing construction expenses as well as future studies on the FCP manufacturing equipment.

“…Most of the studies on the FWS selection problem from 1989 until 2012 considered the FWS selection criteria under the four main groups identified by Hanna [15]. The widespread use of industrial FWSs in building construction projects across the world, as well as new technological advancements in formwork engineering [22,23], necessitated the inclusion of additional criteria in the FWS selection process in the following years. For instance, Krawczyska-Piechna [24] and Krawczyska-Piechna [25] contributed to the relevant literature by introducing criteria, such as flexibility, durability, compatibility, safety, and weight of the FWS for building construction projects in Poland.…”

Formwork System Selection Criteria for Building Construction Projects: A Structural Equation Modelling Approach

Selecting the appropriate formwork system (FWS) is a critical aspect in the successful completion of reinforced concrete (RC) building construction projects. The selected FWS has a significant impact on the cost, time, and quality performances of the project. As there are many FWSs and formwork fabricators (FWFs) available, the selection of the FWS depends on several compromising and conflicting criteria. This study aims to identify the FWS selection criteria groupings (e.g., latent factors) and investigate the quantitative interrelationships among them. For this purpose, 35 FWS selection criteria were identified through literature review, and a questionnaire was developed. The data from the questionnaire were statistically analyzed, and five latent factors were identified: FWS-FWF characteristics, structural design, local conditions, cost, and performance indicators. A conceptual framework was developed based on the latent factors, and a structural equation modelling (SEM) approach was utilized to identify the effects among the latent factors. The results of the SEM approach confirmed that FWS-FWF characteristics are affected by the structural design and local conditions and FWS-FWF characteristics have a substantial effect on cost and the performance indicators of the project. The findings of this study may assist construction professionals in selecting the FWS in building construction projects.
