Oil Palm Industry

Oil palm empty fruit bunch (EFB) is a biomass waste abundantly produced by the oil palm industry in Malaysia. To minimize the environmental impacts, it needs to be properly disposed of or being rapidly consumed as a raw material of another industry. This study investigated the feasibility of substituting EFB in cement bricks, which is in high demand by the construction industry. A total of 120 specimens having the cement-to-sand (c/s) ratios of 1:2.5 and 1:3 were produced in the laboratory. EFB fibre was used to replace 10% to 25% of sand in the mix by volume. The specimens were tested for the compressive strength, density and water absorption after 28 days of casting. For the mix of 1:2.5 c/s ratio, 25% EFB content reduced 22% of density, decreased 59% of compressive strength and increased 43% of water absorption capacity of normal cement brick. This was mainly attributed to the porous cellular structure of EFB fibre that created a large volume of voids in the mix. Based on the feasibility evaluation, EFB fibre can only replace up to 15% and 10% of sand in the mixes of 1:2.5 and 1:3 c/s ratios respectively.

Due to Modernization and urbanization constructing industries are fast growing also it leading to high demand of constructing materials because of expensive prices, and for the construction industry, usage of steel is currently limited heavily Many studies have been carried out to identify highly available, low cost innovative material to use in construction industry as a solution to meet the ever increasing demand for raw material. Bamboo was used as a construction material as a coarse aggregate, steel reinforcement. Bamboo has a higher compressive strength than wood, brick, or concrete and a tensile strength that rivals steel. water absorption in bamboo was the main problem used for construction .because The durability of the concrete is largely affected by absorption of water. Also poly ethylene bags are widely used in the country and its disposal after use causes more problems ,Mismanaged waste of polyethylene bags is the current threatening to the environment this waste is largely availbe its abundant high resistance to insects, fungi, animals, as well as molds, mildew, rot and many chemicals. In this study cubic bamboo was used as a coarse aggregate and it was coated with the waste LDPE bag melt ,as one of the coating material and other one is neem oil.and it was investigated to find the water absorption and turbidity, antifungal activity and compressive strength some other parameters in bamboo material with coatings it was observed that compared to untreated bamboo the polyethylenene coated bamboo material shows reduction in water absorption level and turbity.

Silica fume (SF) and palm oil empty fruit bunch (EFB) are the by-products of the ferroalloy smelting industry and oil palm plantation, which require proper disposal to minimize the environmental impacts. To consume the by-products, the feasibility of utilizing SF and EFB to fabricate bricks was studied. Limited studies were adopting EFB as the natural fibres in bricks and its pro-portion barely exceeded 5%. With the enhancement of SF, EFB content in the mix could be increased. In this study, 336 specimens were produced in the cement-to-sand (c/s) ratios of 1:2.5 and 1:3, where SF replaced 10% to 15% cement in the mix by weight while EFB substituted 20% to 25% sand by volume. The specimens were tested for the compressive strength, density, and water absorption properties. SF was found to strengthen the mix, while EFB reduced the compressive strength and increased the water absorption capacity of the brick. Based on the evaluation results, the mix containing less than 10% SF and 20% EFB content was applicable for non-load-bearing brick.

Oil palm shell ash which is the result of boiler combustion inindustry has the potential to pollute the environment and have a badimpact in the long term so that special treatment is needed. Thisstudy aims to answer this problem by making silica gel fromhazelnut shell and oil palm shell ash with variations in the type ofacid and the ratio of ash to determine the effect of the type of acidand the ratio of the raw material in the form of ash to moisturecontent and water absorption of silica gel. Oil palm shell ash is usedas the main ingredient because it contains the most SiO2compounds compared to other compounds (reaching 39.78%).Candlenut shell is also used as a raw material for silica gel becauseit contains silica (12.58%). The stages in this research include thepretreatment process of the material by washing and drying thematerial, the combustion process of the main ingredient in thefurnace, the process of making sodium silicate and the synthesisprocess of silica gel. Then proceed with water content analysis,analysis of water absorption by silica gel and characterization byScanning Electron Microscope. The results of this study were thatthe type of acid, the concentration of the acid and the time ofmaturation of the gel had an influence on the moisture content ofthe silica gel and the absorption capacity of the silica gel. The silicagel produced using H2SO4 produced more mass than the silica gelusing HCl.

Worldwide, the construction industry has acknowledged the future demand for lightweight construction materials, with high workability, self-compacting, and environmentally friendly. Given this demand, recent innovative material namely foamed concrete (FC), has been found to reduce normal concrete’s weight potentially. However, while FC made with Ordinary Portland Cement has good compressive strength, other characteristics such as tension are relatively weak given the number of micro-cracks. Therefore, the study focused on the potential use of oil palm fibres in FC regarding their durability and mechanical properties. Notably, one of the major issues faced in the construction of reinforced FC is the corrosion of reinforcing steel which affects the behaviour and durability of concrete structures. Hence, in this study, oil palm fibres were added to improve strength and effectively reduce corrosion. Five types of fibre generated from oil palm waste were considered: oil palm trunk, oil palm frond, oil palm mesocarp and empty fruit bunch consisting of the stalk and spikelets. Specimens with a density of 1800 kg/m3 were prepared in which the weight fraction of the fibre content was kept constant at 0.45% for each mixture. Testing ages differed in testing and evaluating the parameters such as compressive strength, flexural strength, tensile strength, porosity, water absorption, drying shrinkage and ultrasonic pulse velocity. The results showed that the incorporation of oil palm fibre in FC helped reduce water absorption, porosity and shrinkage while enhancing the compressive, flexural and tensile strength of FC.

The study of the use of kaolin waste has scientific and socio-environmental value by providing an appropriate destination, reducing the demand and consequent problems arising from its extraction, considering that the construction industry is a consumer of a significant amount of raw material. Thus, the study aims to replace the fine aggregate by kaolin waste in the proportions of 10%, 20% and 30%, verifying its feasibility for interlocking sidewalk pieces. The kaolin waste was used with and without fine material, and physical characterization tests of the materials were performed, and then the concrete pieces were subjected to tests of resistance to simple compression, water absorption and resistance to abrasion, as prescribed by ABNT NBR 9781:2013, and flexural tensile strength test, according to ABNT NBR 12142:2010. According to the results and analyzing the compressive strength at 28 days, the mixtures with replacement of 10% of fine aggregate by kaolin waste reached strengths greater than 35 MPa, an acceptable normative parameter, both for the waste with fines and without fines, making its use feasible.

The accumulation of coconut fibre (CF), oil palm empty fruit bunch (OPEFB), and rice husks (RH) every year can reduce the fertility of soil and water absorption, and causes water acidification. Waste utilization as a filler material of concrete blocks was discussed in this research. Experimental design was used by comparing the quality of concrete blocks based on 36 specimens with varied compositions of waste (1%, 2%, 3%, and 4% by dry weight of total sand) and 3 specimens (0%) as control specimens with 3 replications for each composition. The quality of paving blocks was determined based on the testing of water absorption, porosity, compressive strength, and density. The results revealed that the quality of concrete blocks with the composition of CF (1% and 2%), OPEFB (1% and 2%), and RH (1%) meet the requirements of SNI 03-0691-1996 criteria in category B for parking paver and the maximum composition of each waste materials (3% and 4%) still comply SNI 15-2094-2000 in class 100 and 150 for the block walls. Statistical analysis revealed that the best treatments for compressive strength was RH (1%) and for water absorption it was RH (2%) and CF (4%).

Ceramic ware waste generation is becoming a global concern because of the increasing volume, hazardous nature, limited reusability, and poor waste management practices. This study examined the feasibility and efficacy of the inclusion of this waste as complementary aggregate in solid masonry unit production with bias interest on the compressive strength and water absorbability. Three particle sizes (1.4, 1.7, and 2.0 mm) of crushed ceramic ware waste were blended with natural fine aggregate under three different mix ratios (10, 20, and 30%) to produce the masonry units cured for 7, 14, 21, and 28 days prior to compressive tests analysis. Afterwards, some of the categories cured for 28-days were subjected to water absorption test. Morphology and elemental composition of the aggregates were also inspected using SEM-EDM machine. Also investigated were some of the aggregates’ physical properties. Results indicated that most of the waste-modified solid masonry units not only had water absorption capacity within required standard. The values were equally lower than the unmodified dense block (control) by 27 - 50%. Of the eighteen different categories produced, all M20T14, M20T21, and M30T28 modified dense masonry unit series with P1.7 (1.7 mm) and P2.0 (2.0 mm) particle sizes had high crushing force, compressive strength, and modulus range, which were 57 - 70 kN, 57 - 61 kN, 59 - 76 kN; 5.1 - 5.2 MPa, 5.1 - 5.5 MPa, 5.3 – 6.8 MPa; and 400 – 441 MPa, 411 – 419 MPa, 468 – 480 MPa respectively. Hence, modified masonry units with particle sizes P1.7 and P2.0 under the M20T14, M20T21, and M30T28 series are suitable masonry units for non-loading construction purposes. Interestingly, modified masonry unit (M30P2.0T7) cured under 7 days could also fit into this category. Hence, utilization of ceramic ware waste as co-aggregate in dense masonry units with M20 and M30 series production were established in this study for non-loading construction purposes

This paper discusses a possible solution regarding the final disposal of sludge from Sanitary Sewage Treatment Stations (ET), aiming at environmental preservation. The solid waste generated after the wastewater treatment processes is highly contaminating and detrimental to the area in which it is deposited. Given this, the use of sludge with the application of reuse techniques becomes pertinent, both from the economic point of view and from the ecological point of view. By replacing the use of aggregates from mineral deposits, the main clay raw material in the manufacture of ceramic products (Vieira, 2000), by the treated sludge of WWTP we will save on the sources of granular materials. Aiming its reintegration to the production cycle through the introduction of sludge as raw material incorporated in the ceramic mass in the manufacture of hollow bricks, the viability of use was verified through performance analysis, compared to the control brick made of pottery, without the addition of sludge. Specimens were prepared with three types of samples: 90% clay and 10% sludge; 80% clay and 20% sludge; 70% clay and 30% sludge. Mass loss, water absorption index and compressive strength tests were performed. As for the tests, the specimens with 10% and 20% of sludge were the ones that had better adaptation to the technical requirements, but because it is a larger volume of the residue for the application of reuse techniques, the brick with 20% sludge dosage. is the most suitable. NBR7.171, November 1992: Ceramic Block for masonry; Specification NBR 6.461, June 1983: Masonry Ceramic Block - Compressive Strength Check: Test Method; NBR 8.947, November 1992: Ceramic Tile- Determination of Mass and Water Absorption: Test Method. As for the tests, the specimen with 20% of sludge was the one that had the best adaptation to technical and environmental requirements. The present article approaches a possible solution regarding the destination of the sludge coming from Sanitary Sewage Treatment Stations, aiming at environmental preservation. Aiming at its reintegration into the productive cycle through applications of reuse techniques, the sludge became raw material when the ceramic mass was incorporated into the brick fabrication. Three types of samples were elaborated: 90% of clay and 10% of mud; 80% clay and 20% sludge; 70% clay and 30% sludge. As for the tests, the test specimen with 20% of sludge was the one that had more adequacy to the technical and environmental requirements.

Laterite samples from Ede area with particle components of 19.7% clay, 32.8% silt and 47.5% sand was stabilized with combined cement, lime and bitumen and test for Compressive strength, Linear Shrinkage, Permeability and Water Absorption. The stabilizers were mixed with laterite soil in different ratios and percentage. The laterite carried 90% which is constant while the three stabilizers shared the remaining 10% in varying form. After 28 days of curing, laterite stabilizer with 90% of laterite, 8% of cement, 1% lime and 1% bitumen (LCLB1) possessed compressive strength of 2.01N/mm2. It Water Absorption Capacity was 3.05%. LCLB4 stabilizer (90% laterite, 6% cement, 2% lime and 2% bitumen) has the same compressive strength with LCLB1 stabilizer but with a high Water Absorption Capacity of 4.2%. The stabilizer of 90% laterite, 3.33% cement, 3.33% lime and 3.33% of bitumen (LCLB8) has the lowest compressive strength of 0.74N/mm2 and the highest Water Absorption Capacity of 5.39%. The results shows that LCLB1 stabilizer is a better stabilizer for strength and blocks made from laterite stabilized with it stand a good alternative to sand Crete blocks in building constructions. The combination of these stabilizers in order to determine a most economical volume combination for optimum performance is highly possible and economical.
