“…In regard to the rigid properties and chemical compositions of POBC, the feasibility usages had been studied in term of sustainable construction application as a building material replacements (Shakir et al, 2019). According to Chai et al (2017), POBC can be potentially used as up to 50% of coarse aggregate substitution in size of 4.75-9 mm. Besides, at 100% of POBC coarse aggregate replacement for concrete with w/b ratio of 0.53, the 28-day compressive strength was up to 33 MPa which was only 30% lower than the reference mix made of granite aggregate (Abutaha et al, 2016).…”

This research was conducted to assess the performances of mortars and concretes made from palm oil boiler clinker aggregate (POBC) blending with rice husk ash (RHA) and calcium bentonite (CB). These blends were used to substitute of ordinary Portland cement (OPC) in the combined proportions of 5wt%CB+5wt%RHA, 5wt%CB+15wt%RHA, 15wt%CB+5wt%RHA, 10wt%CB+20wt%RHA, and 20wt%B+10wt%RHA. The POBC mortars were examined for compressive strength, water absorption, sulfuric acid resistance, and microstructural characterization at the age of 7, 28, and 56 days. Subsequently, the POBC concretes were tested for rapid chloride ion permeability and capillary absorption at 28 and 56 days of curing ages. As a result, the 56-day POBC mortar with the optimum blending of 5% CB and 15% RHA provided the greatest compressive strength of 48 MPa as well as revealed denser microstructure observed under scanning electron microscope (SEM) and greater durability against sulfuric acid attack which surpassed those of the POBC mortar without CB and RHA. Proportionately, the incorporation of 5-10% CB with 15-20% RHA to POBC concrete cured up to 56 days possessed greater durability performances by reducing the chloride ion permeability from moderate to very low ranges as well as lessening capillary absorption. The practical implications of this study are that the POBC could be potentially used in the building sector as a substitute to the conventional aggregates. In addition, the use of CB and RHA could be possibly replaced cement in the optimum proportions without compromising the strength and durability to produce efficiently sustainable POBC mortar and concrete.

“…The primary ingredient of concrete is aggregates. Several studies have been conducted to achieve not only a lightweight but also sustainable concrete (Lee et al 2017a;2017b;Shafigh et al 2018). Ground-granulated blast furnace slag, fly ash, and recycled concrete are classified as waste materials that have successfully transformed into aggregate supplant and have been utilized for decades (Federico and Chidiac 2009;Meyer 2009).…”

This paper deals with a comparatively study of the engineering properties of the Oil-palm-boiler clinker (OPBC) OPBC and lightweight expanded clay aggregate (LECA) concretes. A grade 70 normal-weight concrete was designed as control mix. Normal weight coarse aggregate was substituted with OPBC and LECA up to 100% by volume, respectively. Their propertiesworkability, density, compressive strength, splitting tensile strength, flexural strength, modulus of elasticity, and water absorptionwere studied. Results showed that at the same mix proportion, all mixes exhibited acceptable workability, except for concrete containing LECA up to 75% onwards, which required the reduction of superplastisizer dozen to 16%. Mixes with 75% onwards LECA content exhibited acceptable workability. The oven dry density of concrete containing 100% OPBC and 50% LECA onwards, respectively, in this study can be considered as lightweight concrete. The use of saturated OPBC and LECA in concrete improves the mechanical properties of concrete under air drying condition. The ceiling strength of LECA concrete is at the early age of 7 days, whereas it happens to normal weight concrete and OPBC concrete at a later age. The water absorption of all mixes is below 3%, which can be considered as good concrete.
