“…Central to this is the utilization of waste products in construction activities. For example, recycled and waste materials can be used to replace either the aggregate or cement in the production of concrete [Black 2016, El-Darwish et al 1997, Hadjsadok et al 2012, Herki and Khatib 2016, Khatib 2009, Khatib 2014, Khatib et al 2006, Khatib et al 2008, Khatib et al 2013a, Khatib et al 2013b, Kurdi et al 1996, Menadi et al 2014, Morales-Hernandez et al 2005, Owens et al 2016, Zhansaya 2014.…”

Nowadays, remarkable achievements towards the sustainability of our environment. These include the use of recyclable materials to improve the greenness of the concrete by incorporating them in the concrete industry. One of the main concerns for researchers when using new material in concrete is its engineering and durability properties. This study was conducted to investigate the mechanical properties and the durability of concrete when using Municipal Solid Waste Incineration Bottom Ash (MSWIBA) as a replacement for fine aggregate to produce green and sustainable concrete. Two percentages for sand replacement 25% and 50% were used to evaluate the effect of incorporating this material on the concrete compressive strength, density, UPV, total water absorption, and capillary water absorption properties. The water to cement ratio used was 0.45, and the specimens were tested at 7,14, and 28 days. A comparison for the results of concrete specimens with and without MSWI-BA was performed. The results showed that replacing 25% of sand with MSWI-BA has no harmful effect on the compressive strength of the concrete that encourages this strategy. However, using higher replacement percentage 50% decreases sharply the strengths to about 50%. On the other hand, water absorption by total immersion and by capillary increased when replacing sand was with 25% and 50% MSWI-BA. In summary, using 25 % of MSWI-BA as sand replacement is an effective strategy to produce eco-friendly concrete in that it would produce concrete material that has less embodied energy to produce.

“…Recently, studies (Whittaker et al, 2014;Otieno et al, 2014;Whittaker et al, 2016;Ogirigbo and Black, 2016;Ogirigbo and Black, 2017;Ukpata et al, 2017) are beginning to look at the impact of chemical composition of GGBS on its performance as a cementitious material. This is because the chemical composition of GGBS is not Accepted manuscript doi: 10.1680/jadcr.17.00152 fixed and can vary depending on the nature of the ore, type of iron or steel being produced and the composition of the limestone flux (Black, 2016). Thus a change in chemical composition is likely to impact on the performance of slag blends, especially in chloride environments.…”

“…POC is produced differently to another palm oil by-product (POBP) commonly utilised in concrete which is palm oil fuel ash (POFA). Fuel ash or fly ash is driven out of the boiler together with other flue gases and collected by particle filtration or electrostatic precipitators (Black, 2016). On the other hand, ash which settles towards the bottom of the boiler and fuses together is known as clinker (Sims and Brown, 1998).…”

Palm oil clinker (POC) is a by-product derived from crude palm oil (CPO) production. Many studies have examined POC in concrete and it has often been stated as being environmentally sustainable. However, evidence to support these claims are not abundant in the literature. Therefore, this study aimed to assess the environmental impact of POC using a comparative, midpoints life cycle assessment approach based on 13 impact categories from ReCiPe2016. The use of POC as a binder replacement, fine aggregate and coarse aggregate was considered. Only production of cement, sand, gravel, POC and transportation were included in the system boundary. The construction, service and end-of-life phases were excluded. A volume of 1 m 3 mortar or concrete with similar compressive strength was used as the functional unit. Life cycle inventory data was obtained from the literature, Malaysia Life Cycle Inventory Database (MY-LCID) and Ecoinvent database. Economic and mass allocation factors were calculated for POC. Calculations indicated that the use of POC in mortar and concrete showed reductions in all impact categories when economically allocated. When mass allocated, POC contributed minimally to all impact categories except 'Freshwater Eutrophication' and 'Human Toxicity'. Despite these drawbacks, results show that use of POC resulted in an overall improvement for the environmental sustainability.
