“…Oil palm shell (OPS) is not frequently consumed in the building construction industry but is regularly curbed as wastes generated from agricultural bases [30]. Numerous proposals focusing on minimizing traditional building material costs have been deliberated by using such kind of agro-wastes with the pursuit of affordable housing system for both the rural and urban populations of Malaysia and other developing countries.…”

Oil palm is known as Elaeis guineensis, found in Africa, South East Asia and China. Oil palm shell is used to prepare activated carbon because of high carbon content, high surface area, highly developed porosity and low price. During the physical activation, carbonization occurs in order to create porosity in the raw material. Literature review indicated that carbon material was impregnated with chemical agents such as phosphoric acid, potassium hydroxide, sulphuric acid, sodium hydroxide and zinc chloride in chemical activation process. Experimental results showed that the obtained activated carbon was used in hydrogen storage purpose, supercapacitor, gases and liquid phase adsorption process. On the other hand, oil palm shell was used in manufacturing lightweight concrete because of lighter and will not produce toxic substance. The bulk density and compressive strength of oil palm shell-based concrete were 500 -600 kg/m 3 and more than 25 MPa, respectively.

“…Subsequently, air foam was added and mixed with the slurry. e desired density of air-cement-treated soil was adjusted to achieve the target density within a range of ±0.03 g/cm 3 , and the range of owability values for the ow test was between 16 and 20 cm [39]. Since the foam has water, the overall water content of the clay-water-cement-foam just after the time of mixing was the total remolding water plus the water in the foam.…”

“…Two main categories of soil improvement include improvement of the in situ foundation soil and improvement of the filled soil. Lightweight cement-treated soil is well recognized among geotechnical engineers and has been used in many civil engineering applications, such as embankment material on soft ground, backfill material, filling material, and filter material [1][2][3]. is improvement technique was first used in Norway for road embankment structures in 1972 [4], and later, the volume of such constructions increased rapidly.…”

This study examines the effect of polypropylene fiber on the flexural strength properties of lightweight foam mixed soil (LFS). The flexural properties of LFS comprising different proportions of polypropylene fiber (58 mm) at different volume fractions (0.5%, 0.75%, and 1%), three different cement contents of 100, 150, and 200 kg/m3, and densities of 0.8, 1.0, and 1.2 g/cm3 were thoroughly investigated. The flexural performance of LFS according to ASTM C1609 was achieved after 28 days of aging. The results show that the flexural characteristics of LFS could be enhanced by fiber additives, as indicated by the increase in the flexural/residual strength and equivalent flexural strength ratio. The flexural performance is also related to the mixing components, including the density and cement content. For the toughness behavior, the equivalent flexural strength ratio reached up to 100%, which could be achieved with the strain-hardening specimens. The fiber inclusion is more efficient with an increase in the density and cement content of specimens as shown by the overall rating of the flexural performance.

Masonry construction is the most widely used building method in the world. Concrete masonry is relatively low in cost due to the vast availability of aggregates used within the production process. ese aggregate materials are not always reliable for structural use. One of the principal issues associated with masonry is the brittleness of the unit. When subject to seismic loads, the brittleness of the masonry magni es. In regions with high seismic activity and unspeci ed building codes or standards, masonry housing has developed into a death trap for countless individuals. A common approach concerning the issue associated with the brittle characteristic of masonry is addition of steel reinforcement. However, this can be expensive, highly dependent on skillfulness of labor, and particularly dependent on the quality of available steel. A proposed solution presented in this investigation consists of introducing steel bers to the lightweight aggregate concrete masonry mix. Previous investigations in the eld of lightweight aggregate ber-reinforced concrete have shown an increase in exural strength, toughness, and ductility. e outcome of this research project provides invaluable data for the production of a ductile masonry unit capable of withstanding seismic loads for prolonged periods.
