“…Enhancement in flow diameters due to increase in FC can be attributed to the solid content decline and porosity increase as also stated by the previous investigations. [6][7][8][9] It can be noticed that reduction in flow diameters increased with increasing FC due to BF.…”

“…Therefore, it is widely applied in civil engineering fields such as filling in soft ground area, bridge padding, backfilling in retaining wall, widening of road embankments, insulated wall panels, filling of tunnels, and floor insulation. [1][2][3][4][5][6][7][8][9][10][11][12] Despite its disadvantages such as drying shrinkage, foam concrete has important advantages such as low cost, strong durability, simple production process, and cast-in-place. The use of waste by-products and waste materials from industries as construction materials is becoming increasingly common and many studies are being carried out.…”

As a typical cellular lightweight material, foam concrete is produced by mixing cement, water, aggregate and a suitable foaming agent and has a density usually below 1600 kg/m3. The large number of air spaces present in foam concrete ensures that the concrete has advantages such as lightweight, high fluidity during pouring, excellent thermal and sound insulation, superior fire resistance, and outstanding energy absorption capacity. Its high porosity and the connectivity of the pores, which can allow the entry of negative substances into the concrete environment, cause foam concrete to have a very low physico‐mechanical and durability performance. To eliminate or reduce these disadvantages, this study adopted the use of basalt fibers (BF) as eco‐friendly fiber type and calcium aluminate cement (CAC) as aluminous cement with waste marble powder (WMP) as aggregates in foam concrete. In that respect, 9 mixes with varying content of foaming agent (FC) and basalt fiber have been prepared. Assessment of mechanical performance was based on compressive and flexural strength after 6 h, 1, 7, and 28 days. Dry bulk density, thermal conductivity, porosity, water absorption, and sorptivity of the concretes were determined. Durability characteristics of the concretes were examined by dry shrinkage, high temperature, magnesium sulfate, sulfuric, and hydrochloric acids. The obtained results showed that the content of BF affected the compressive strength of the mixtures slightly negatively or positively depending on the FC. The lowest value in thermal conductivity was gained as 0.645 (W/m K) for the mixture incorporating 1% BF and 50 kg/m3 foam quantity. In addition, the foam concrete incorporating foam of 30 kg/m3 and 1% BF showed the best resistance against MgSO4. The mixture with 2% BF and 30 kg/m3 FC exhibited the lowest mass loss after HCI exposure.

“…With proper control of the quantity of foam added to the mortar slurry, an extensive variety of densities can be produced ranging between 400 and 1900 kg/m 3 [4]. LFC is regarded as an economical substitute in the production process pertaining to large-scale lightweight construction components, such as road embankment infills, wall panels, structural elements, and filling grades due to its easy and simple manufacturing process, which encompasses all stages, right from the start of the manufacturing plants to the final position [5][6][7].…”

Durability Properties of Lightweight Foamed Concrete Reinforced with Lignocellulosic Fibers

et al. 2022

Worldwide concern and ascendancy of emissions and carbon footprints have propelled a substantial number of explorations into green concrete technology. Furthermore, construction material costs have increased along with their gradual impact on the environment, which has led researchers to recognize the importance of natural fibers in improving the durability and mechanical properties of concrete. Natural fibers are abundantly available making them relatively relevant as a reinforcing material in concrete. Presently, it should be recognized that most construction products are manufactured using resources that demand a high quantity of energy and are not sustainable, which may lead to a global crisis. Consequently, the use of plant fibers in lightweight foamed concrete (LFC) is deemed a practical possibility for making concrete a sustainable material that responds to this dilemma. The main objective of this study is to investigate the effect of the addition of lignocellulosic fibers on the performance of LFC. In this investigation, four different types of lignocellulosic plant fibers were considered which were kenaf, ramie, hemp and jute fibers. A total of ten mixes were made and tested in this study. LFC samples with a density of 700 kg/m3 and 1400 kg/m3 were fabricated. The weight fraction for the lignocellulosic plant fibers was kept at 0.45%. The durability parameters assessed were flowability, water absorption capability, porosity and ultrasonic pulse velocity (UPV). The results revealed that the presence of cellulosic plant fibers in LFC plays an important role in enhancing all the durability parameters considered in this study. For workability, the addition of ramie fiber led to the lowest slump while the inclusion of kenaf fiber provided optimum UPV. For porosity and water absorption, the addition of jute fiber led to the best results.

“…The demand for urban areas increases the need for new residential areas [18][19][20] and construction of new housings [21][22][23]. This need also increases the demand for concrete, which is an important raw material especially in the building industry and constitutes an important share of construction costs [24][25][26].…”

Palm leaves are vegetal waste that are not widely used by the society, only piled up and causing odors that mix with the environment. Channeling this waste material into the construction industry helps to overcome waste disposal problems as well as promote sustainability. The most important features expected from the buildings are the creation of the most suitable environmental conditions for the products to be stored or the creatures that will live in them, and they can be used safely for a long time. In the construction of the buildings, materials that are the cheapest possible, safe and capable of creating the optimum environmental conditions should be used. The materials to be selected should have sufficient strength and durability, high heat and sound insulation and lightness. Since single-storey buildings are not subject to excessive load, it is important that the thermal insulation is high and light in material selection. Since the widespread use of concrete as a building material in the world, efforts to make concrete light, cheaper and better insulating have gained importance. Lightweight concrete, which is easy to apply, has been an important building material in recent years. With the use of lightweight concrete as a building material, benefits such as economy in terms of material, earthquake resistance, and the elimination of a second insulation material for heat and sound insulation can be achieved. In this study; Experimental study using Portland cement (CEM I), Palm Leaf, CEN standard sand and water mortar production; sample production, curing, some physical and mechanical experiments were carried out in four stages. The usability of palm leaf, which is a vegetable waste, as aggregate in concrete production by replacing it with CEN standard sand at 0, 5, 10, 20, 30 and 40% as well as 10% with cement has been investigated. The study results show that the addition of both ground palm leaf and palm leaf aggregate significantly altered almost all properties of concrete. These changes are at different levels in terms of physical properties. As a result of the study, it was determined that as the amount of foam increased, the spreading diameter increased, whereas palm leaf addition decreased the spreading diameter. It has been determined that the addition of palm leaf decreases the depth of water treatment depending on time, the porosity of the samples with high level of palm leaf addition increases and the compression and bending strength decreases.
