“…It is generated by the incineration of oil palm shell and palm oil empty fruit bunch at 800Cº to 1000Cº as a mean of heating up the mill's boilers instead of using conventional fuels. Due to this incineration process, ash is produced at about 5% by weight of the incinerated solid fuels [5]. The quantity of OPA produced in Malaysia alone is about 4 million tonnes a year [6].…”

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.

“…In addition, the second aspect is to utilize the other alternative materials such as waste ash from boiler of palm oil mill industry. Because this material composition has the silica content which can be replaced in laterite soil and fluvial sand [13]. Furthermore, increasing the composition of Portland cement in the formula should be considered [10].…”

Abstract. Utilizing crushed limestone dust; the by-product of crushing limestone plant for producing non-fired wall tiles is the objective of this research. The main raw materials of non-fired wall tiles consist of laterite soil, fluvial sand and Portland cement. The crushed limestone dust has been used as the substitute material of non-fired wall tiles for enhancing their bending strength. In this experiment, four groups of formulas have been constructed. Firstly, crushed limestone dust has been mixed into the basic formula for substitution of laterite soil. Secondly, crushed limestone dust has been used for substitution to river soil of the basic formula. Thirdly, it has been substituted to Portland cement in the basic formula. Finally, the best formulas of the first three groups has been selected and mixed up to make the new formulas. After mixing the raw materials of selected formula, forming specimens by uni-axial pressing at 100 bar has been performed. Then, they have been aged for 1 week at the room temperature. After that, testing the specimens' properties has been carried out. They are bending strength and water absorption which comparing with Thailand Industrial Standard (TIS) 614-2529. The experimental results show that adding the crushed limestone dust to the basic composition has an effect on the bending strength and water absorption. The compositions of the best formula are laterite soil 55%, fluvial sand 7.5%, Portland cement 22.5%, and crushed limestone dust 15%. It gives the bending strength by 2.32 MPa, water absorption 3.20%. The water absorption property can pass the TIS standard, but bending strength could not pass. The estimated cost of raw materials is 0.09065 THB/100 g.

“…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.…”

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.
