“…This is also attributed to the fact that less matrix is available to fill the pores within the POC aggregates, leading to a higher total porosity in the concrete as observed in Figure 11. Abutaha et al (2016) [17], and Ibrahim et al (2017) [18] reported that the porosity of POC and the lower aggregate crushing value negatively affected the compressive strength when compared to the control mix. This also corroborates the results of the study by Rashid et al (2012) [1] on the utilization of LWA from waste material by using crushed clay bricks as a coarse aggregate replacement.…”

Palm oil clinker (POC) is a waste material generated in large quantities from the palm oil industry. POC, when crushed, possesses the potential to serve as an aggregate for concrete production. Experimental investigation on the engineering properties of concrete incorporating POC as aggregate and filler material was carried out in this study. POC was partially and fully used to replace natural coarse aggregate. The volumetric replacements used were 0, 20%, 40%, 60%, 80%, and 100%. POC, being highly porous, negatively affected the fresh and hardened concrete properties. Therefore, the particle-packing (PP) method was adopted to measure the surface and inner voids of POC coarse aggregate in the mixtures at different substitution levels. In order to enhance the engineering properties of the POC concrete, palm oil clinker powder (POCP) was used as a filler material to fill up and coat the surface voids of POC coarse, while the rest of the mix constituents were left as the same. Fresh and hardened properties of the POC concrete with and without coating were determined, and the results were compared with the control concrete. The results revealed that coating the surface voids of POC coarse with POCP significantly improved the engineering properties as well as the durability performance of the POC concrete. Furthermore, using POC as an aggregate and filler material may reduce the continuous exploitation of aggregates from primary sources. Also, this approach offers an environmental friendly solution to the ongoing waste problems associated with palm oil waste material.

The objective of this research paper is to discuss the main requirements which may affect the sustainability of concrete structures and develop the relative weights of these requirements. A questionnaire survey was conducted among construction experts, such as college staff, contractors and construction engineers. The survey was conducted to identify the relative weights of the concrete sustainability requirements. After reviewing literature, fifty nine factors which affect the concrete sustainability were prepared and divided them into 12 categories. A pilot study was conducted by 19% of sample size to enhance the questionnaire design. The pilot study was filled out by 10 college professors and 9 engineers with experience more than 10 years. This study helped us to modify the requirements which were directly connected with the concrete sustainability. Researchers found that the most important factors were related to "Aggregate" category. Aggregate category has the weight of 17.64% and waste category has the weight of 13.04%. These two categories have about 30% of concrete sustainability weight. The Green Pyramid Rating System (GPRS) was used in the present research to know what could be added.
