“…While a 35% replacement exhibited 41% increase than the control mix's strength at 28 days. This can only be explained by the fact the OPA used, despite its large particle size, has a high content of (SiO 2 ) (66.6411%) enabling it to react with the Calcium Hydroxide (Ca(OH) 2 ) producing additional Calcium Silicate Hydrates (C-S-H); hence, causing the improvement of the compressive strength [11].…”

“…Therefore, a number of studies focused on the utilisation of OPA in the construction industry as a mean of recycling such a waste. OPA has been used as a binder or filler replacement in normal concrete [8,9,10], high strength concrete [11,12], mortar [10,13] and aerated concrete [14,15,16]. This study is a part of an on-going research studying the effects of semi-processed OPA on the properties of foam concrete when used as a cement replacement.…”

Abstract. This study is a part of an on-going research examining the properties of foam concrete when replacing the cement with semi-processed Oil Palm Ash (OPA). Replacements range from 25% to 65% were used for a mix having the mix ratio of (1:2:0.45) and having the target density of 1300kg/m 3 . All mixes were tested for their strength using the compressive, splitting tensile and flexural strengths up to the age of 28 days. Results show that a 25% replacement level exhibited higher compressive and splitting tensile strength than that of the control mix at the age of 28 days. However, the same replacement level exhibited a close strength to that of the control mix when tested for the flexural strength at the same age.

“…These bars were having 12 mm diameter with 800 mm long and were used as a replacement for steel balls [38]. Depending on the carbon content of the ashes produced, their colors vary from light grey to dark grey [37,[39][40][41][42][43][44]. Finally, it was understood that the fuel industry is the main sources of the raw materials of the POFA, being incinerated in a boiler or other grinding industries.…”

Toward Sustainability in Concrete Industry by Using Of Solid Wastes from Palm Oil Industry

Abstract. Nowadays, one of the most important construction materials is concrete. By the advances of the industries in the urban areas, concrete is considered as one of the highest demands. As a result, the large amount of unprocessed materials is needed for making concrete. In the meantime, the agricultural wastes and solid material disposal are giving serious damages to the environment. As a result, by employing the agricultural wastes as a cementitious material, the undesirable impacts of the concrete industry to the environment will be dramatically decreased. That's because the source of these newly developed concretes is both reliable and environmental friendly. In this study, the utilization of agricultural wastes as a complementary cementitious material for producing the concrete is explained. In addition, it discusses the possibility of deploying the agricultural wastes by considering their engineering, physical and chemical properties. In addition, the successful use of agricultural wastes from oil palm industry such as oil palm shell, palm oil fuel ash and palm oil fibre in the concrete mixture was reported.

“…These materials are commonly used to strengthen the concrete by pozzolanic reaction and improve the quality of the concrete. Experimental results obtained by Sata et al (1) suggested that pozzolanic materials could be used as an OPC replacement to produce HS-C, there being no negative impact on the mechanical properties of the concrete. Similarly, Nath and Sarker (2) reported that fly ash could improve the durability of HS-C with respect to chloride penetration resistance and drying shrinkage.…”

ABSTRACT:This research aimed to use of bagasse ash as a cement replacement in high-strength recycled aggregate concrete (HS-RAC). Crushed limestone was replaced with 100% recycled concrete aggregate (RCA) and the ground bagasse ash (GBA) was used to partially replace ordinary Portland cement (OPC) at 20, 35 and 50%wt of binder to cast HS-RAC. The results indicated that the replacing of crushed limestone with RCA had a negative impact on the properties of the concrete. Increasing the amount of GBA in HS-RAC resulted in a decrease in density and an increase in the volume of permeable pore space. The concrete mixtures prepared with 20%wt GBA replacement of OPC promoted greater the compressive strength than the conventional concrete (CT concrete) at 90 days or more. HS-RAC with GBA (up to 50%) was more durable in terms of chloride ion penetration resistance, although it had lower compressive strength than the CT concrete. RESUMEN: Influencia de la ceniza de bagazo y los áridos de hormigón reciclado en las propiedades de endurecimiento de hormigones de alta resistencia.En esta investigación se utilizó ceniza de bagazo como sustituto del cemento en hormigón de alta resistencia con áridos reciclados (HS-RAC). La piedra caliza fue sustituida por un árido 100% reciclado de hormigón y la ceniza de bagazo molida (GBA) en diferentes porcentajes (20, 35 y 50% en peso del material cementante) fue utilizada para reemplazar parcialmente al cemento Portland para producir hormigón de tipo HS-RAC. Los resultados indicaron que la sustitución de la piedra caliza molida por áridos de hormigón reciclado tiene un efecto negativo en las propiedades del hormigón. Aumentar la cantidad de GBA en el HS-RAC redujo la densidad e incrementó el volumen del espacio de los poros permeables. Las mezclas de hormigón preparadas reemplazando 20% en peso del cemento Portland por ceniza de bagazo molida presentaron mayor resistencia a la compresión que el hormigón convencional a los 90 días o más. El HS-RAC con GBA (hasta 50%) tuvo una durabilidad mayor que el hormigón convencional en términos de resistencia a la penetración de iones de cloruro, a pesar de tener una menor resistencia a la compresión.PALABRAS CLAVE: Hormigón; Árido; Resistencia a la compresión; Durabilidad; Cloruros ORCID ID: P.
