Abstract

This study aims to investigate the mechanical properties of lightweight concrete using lightweight aggregate and analyze the impact of silica fume on enhancing its compressive strength. The main objective of this study was to improve the value of industrial waste by utilizing GGBFS as a substitute for cement. Four alternative compositions have been used to produce samples of lightweight concrete. The coarse aggregate is substituted with 100% lightweight expanded clay aggregate, whereas the fine aggregates are replaced with 100% vermiculite and 100% polystyrene bead waste.                                A combination of 20% GGBFS and 10% silica fume is employed for cement replacement. The materials used throughout this study consist of aluminum powder and superplasticizer. The workability, compressive strength, tensile strength, and specific gravity of concrete will be determined by testing.                  The waster curing will be carried out on cylindrical concrete specimens 200 mm in height and 100 mm in diameter. Experimental results showed that the concrete mixture consisting of 80% cement and 20% GGBFS as binders, along with lightweight expanded clay aggregate as coarse aggregate and vermiculite as the fine aggregate, exhibits the highest compressive strength compared to other lightweight concrete mixtures.

Abstract

Prefabricated buildings represent a novel approach to construction, characterized by standardized designs, factory-based processing, and assembly-line operations. Over the recent years, the continuous advancement and maturation of BIM (Building Information Modeling) technology have fostered advantageous conditions for the enhancement and transformation of the construction sector. Prefabricated buildings integrate a variety of digital technologies to break down barriers in various links of the traditional construction industry. This approach effectively fosters information sharing and resource substitution across different stages and among various stakeholders in construction, thereby preventing issues such as inadequate information communication that often arise during the building process. This review elucidates the prevalent employment of BIM technology in PB (prefabricated buildings) through a systematic literature review and content analysis. A three-stage systematic literature review approach was adopted to identify and review 81 relevant articles, culminating in a summary outlining the contribution, development trends, and restriction of BIM technology in PB. The review also emphasises the potential of BIM technology, but the need for effective integration of the technology to improve future prefabrication practices

Abstract

Assessing the quality of MRT services unveils a generally satisfactory experience among respondents, with comfort emerging as a particularly noteworthy aspect. Satisfaction levels for MRT service quality range from 3.63 to 4.12, indicating a favorable perception overall. Notably, comfort stands out with the highest satisfaction rating, surpassing the "Satisfied" threshold, while accessibility receives the lowest rating. In essence, the majority of MRT passengers’ express contentment with the service, spanning operation, maintenance, and performance. Additionally, Bukit Bintang station emerges as a focal point during peak hours due to its proximity to diverse amenities. However, the prevalence of respondents underscores the necessity for broader demographic representation in future studies. Anticipated increases in MRT ridership necessitate proactive measures to accommodate the growing demand, with projected passenger numbers expected to rise significantly. Peak demand for the MRT SBK line is estimated at 115,498.543 passengers per day, reflecting a notable escalation of 281.82% across various purposes. Yet, reliance on responses may introduce biases in trip generation models and subsequent travel demand forecasting, emphasizing the importance of diversifying the respondent pool for more accurate predictions. Overall, the evaluation underscores the satisfactory nature of MRT services, particularly in terms of passenger comfort.

Abstract

Many researchers' interest in carbon nanotube (CNT) materials has grown as a result of their potential use in the construction industry. This is mostly related to the mechanical, electrical, thermal, kinetic, and chemical properties of CNT, which have a big impact on the way concrete functions. Hydrated calcium silicate is a complex network of binding particles that compose the cement composite material known as concrete. Since it has nanoscale features, CNT will interact most strongly with hydrated calcium silicate, improving the concrete's mechanical qualities. The purpose of this study is to ascertain the impact of adding CNT to concrete mixtures. Three distinct mixes were created by varying the types and amounts of admixtures that were added to the concrete mix.  Two mixed variations employed CNT at various doses, while one mixed variation used admixture type F (superplasticizer), and the performance of one was compared to the other. Concrete that was both new and hard underwent specimen testing. On fresh concrete, a slump test was conducted using ASTM C163, while for hard concrete, cylindrical specimens measuring 100 mm x 200 mm were tested for unit weight and compressive strength at 7, 14, and 28 days following ASTM C39. According to the test results, utilizing CNT at a lower dose than the typical superplasticizer dose leads to greater workability and compressive strength. The results of the workability and compressive strength tests will be improved by the inclusion of CNT.
