“…The use of 30% BFS in concrete mixtures is desirable because it is environmentally friendly, and the economic advantages in reducing overall cement expenditures (Labarca et al 2007). According to Al-Baijat & Sarireh (2019), the replacement of concrete by BFS lowering the cost of the concrete mixed as slag is much cheaper than regular concrete. BFS is not widely used due to its relatively low initial strength and increased shrinkage compared to regular concrete that must be included (Lee et al 2019).…”

Carbon emission is released into the atmosphere as the result of various activities due to rapid urbanisation and thus contributed to global warming and climate change. The government has taken various initiatives to reduce the impact, including from the construction industry in order to support the carbon footprint reduction of 40% as pledged by the Prime Minister. Various strategies, such as the Malaysian Carbon Reduction and Environmental Sustainability Tool (MyCREST), have been established to promote green building development in Malaysia. Recent studies suggested that the selection of sustainable materials can reduce the overall carbon emission of a building, but the cost has been identified as the main barriers. This paper aims to analyse the potential of carbon footprint reduction by using sustainable material in mid-rise residential building and subsequently to evaluate the cost implication. The impact of the conventional and the selected sustainable materials was assessed using data from the MyCREST tool while the data for cost analysis were taken from various sources of cost data such as JKR Rates online (RATOL), JKR Sarawak Schedule of Rates (SOR), and previous research. The results show that the sustainable materials such as 30% of Blast Furnace Slag (BFS) concrete mixture, Aerated Autoclaved Concrete (AAC) block, and recycled steel roof truss has the potential to reduce the carbon emission. The findings also show that sustainable materials are slightly cheaper than the conventional materials except for the AAC block and clay roof tiles. Therefore, the potential of carbon emission reduction approach by using MyCREST as a guideline tool can assist in the reduction of the environmental impact of buildings.Keywords: Carbon emission, sustainable building materials, cost implication.

“…Aggregate occupies 75% of concrete volume and gives volumes stability to concrete and responsible mainly for strength. Concrete mix in all its grades consumes crushed limestone aggregate (CLA) that mined in a continuous operation from local stations and plants in huge quantities and transported to farther sites, so rounded valley aggregate (RVA) becomes an important source for aggregate surface mining and concrete production [1]. The use of RVA is more economical and eff ective in achieving the desired concrete compressive strength and other properties of concrete.…”

Round valley aggregate RVA is a natural source of aggregate that is found in Tafi la in Jordan. For current research, RVA from Al-Hasa valley was considered for testing with crushed limestone aggregate (CLA) from Karak and Tafi la sources. 39 samples were collected through the valley at the joint with the lake of Al-Tanour Dam in Tafi la. Samples of RVA and CLA were tested and concrete mix at 15, 20, and 25 MPa. ANOVA analysis was conducted to test means' diff erences in aggregate and concrete properties. Results showed that RVVA has no signifi cant diff erence in means' properties. While RVA has signifi cant diff erences when with CLA from Karak and Tafi la. Results of ANOVA showed that there is a signifi cant diff erence in the properties of fresh and hardened concrete for 15 and 25 MPa concrete grades. While signifi cant diff erence is neglected for 20 MPa concrete grade. Consequently, RVA can be used for concrete mix as CLA.

“…It was classified as an amorphous material and called granulated blast furnace slag when it is being used as a binder material and classified as a crystalline material and called gradually-cooled blast furnace slag when it is being used as a material for road paving [1]. The use of fine blast furnace slag (BFS) is widely applicable to increase the strength of concrete, especially the late age strength [2].…”

This research showed the application of concrete material in construction industry were highly demand which growing rapidly demonstrate the need for various types and properties of concrete to meet the diverse needs of the user. Normally, the quality of concrete with high durability properties can be generated by consideration of the composition of the materials used such as cement, sand, aggregates or water. Besides that, mix design and the way of production like mixing, transporting and pouring concrete is also the factors to get a better quality of concrete. Recently, the sustainability in construction is one of the efforts that have been practiced by developed countries to create healthier environment and to reduce the environmental impact of a building over its entire lifetime, while optimizing its economic viability and the comfort and safety of its occupants. One of the steps that can be practice is to use materials that are categorized as agricultural waste material such as palm oil fuel ash, rice husk, fly ash slag, sludge, coconut shell and etc. in concrete manufacturing. Hence, the objective of this paper is to evaluate the performance of blast furnace slag, rice husk ash and coconut shell as partial replacement of aggregates in cement. A series of test were conducted to investigate the performance of blast furnace slag, rice husk ash and coconut shell as partial replacement of aggregates in cement. The tests that are being conducted are compressive strength test, flexural strength test, rebound hammer test, ultrasonic pulse velocity test, water permeability test, sieve analysis test, water absorption test, carbonation test, alkali-silica reaction test, SEM test and shrinkage test.
