This paper investigates the potential of using cork and olive stone waste as lightweight aggregates in repointing mortars for the rehabilitation of old buildings. For this purpose, mortar blends were prepared like 1/3 mortar partly replacing ordinary sand with different percentages of cork or olive stones aggregates with a grain size of 0-4 mm. The partial substitution rates are: 5, 10, 15, 20, 25 and 30% respectively with a constant amount of binder (Portland cement CEM I 42.5R). All Specimens prepared were remolded after 24h then cured in potable water at 20±2°C until the date of the test. In course of this research, the mechanical and physical features were highlighted while taking into account certain parameters such as consistency, fresh density, mechanical performance (compressive strength, tensile strength), durability (absorption in immersion, capillary water absorption coefficient and chloride penetration). The results demonstrated that incorporating 30% olive stone waste as a sand replacement in the mortar resulted in improved durability and long-term performance compared to control blends. Additionally, all mortars containing lightweight aggregates were lighter than the control mortar.

“…The materials were weighted according to their mixing ratio, considering their actual moisture, and then were homogenized according to the recipe of every mixture separated in a kneading mixer where the necessary preparation water added. The addition of water was continued until a satisfactory plasticity index (Pfefferkorn's test) [31]. The Pfefferkorn plasticity method is based on the verification of the deformation of the sample as a result of the fall of the calibrated plate on the underlying test body shaped by means of the ancillary shaping tool.…”

The advent of new materials and technologies in building materials has changed the way of building. New lighter materials with easier application methods and improved mechanical behaviors, have become necessary for the market. Moreover, the new environmental policy (2022) aims to transform the waste management into sustainable materials management to ensure the long-term protection and improvement of the environment. For the brick and tile industry, raw materials and the additives that compose the product mixture seem to be a key factor in this direction. Furthermore, every product type (solid or perforated brick) requires different additives to achieve the properties that are postulated by the international standards. For the study, the wide range of additives that were used have been assorted into three (3) categories: the inert materials, the lightweight materials, and the industrial remains. Totally, eight (8) different materials were used as additives into ceramic mass, in different proportions each time. Almost all additives used for this research were pore-forming agents. These burn out almost completely before reaching the full-fire temperature, and do not change the fired body. As a result of additives burnt out, the necessary pore volume is formed in the fired brick body, which, if combined with an appropriate percentage of voids, result in raw density readings. The pore structure is significant as long as the ultimate strength of lightweight bricks is acceptable. In this study, additives between 3 and 25% by weight were added to the clay mixture. The extrusion of specimens in solid form was carried out using the Laboratory’s vacuum press. Firstly, the extrusion of specimens from the original raw material was implemented. Secondly, it was made on the material mixed with the additives mentioned above. A series of experimental activities were followed to determine the variations of the mechanical and physical properties as well as their production procedures (extrusion, drying, and firing). According to five (5) key properties measured in the current study and compared with the mixture without additives, it was found that the variation in thermal conductivity improvement is between -11% and 19%. The bending strength of the fired products showed a decrease from 16% to 55% except for the addition of bauxite residue, which increased the strength by 8%. Bigot drying sensitivity decreased from 11% to 27%. The density in two cases increased from 2% to 7% while in the majority the mixtures with the additives showed a decrease in density from 1% to 14%. Finally, the addition of the necessary water for shaping during extrusion showed a variation from a 10% decreased to a 14% increased water.

“…These materials refer to bricks that are lighter than traditional bricks, and are primarily aimed at improving thermal insulation. In this line of research, a number of residues have already been tested, including sawdust, charcoal, paper sludge and straw [2], crushed date stone [3], olive pomace [4], rice husk ash [5], tea waste [6], cherry seeds [7], cigarette butts [8], and peanut hulls used as a partial replacement for sand in cement blocks [9]. Lamrani et al [10] have used peanut shells as an additive in plaster to improve insulation and reduce density.…”

The quantity of solid wastes (domestic, agricultural or industrial) throughout the world is increasing and their elimination becomes more complex. However, recycling industrial by-product materials waste has become an attractive topic of materials research in civil engineering. These industrial by-product materials waste must be managed responsibly to insure a clean environment. The use of waste in fired clay brick production may also save clay from avoidable depletion and reduce the environmental contamination by waste, contributing to sustainability. The aim of this research is to study the influence of Ground Cork Waste (GCW) on the thermo-mechanical properties of fired clay brick. For this purpose, increasing amounts of Cork Waste (0, 5, 10 and 15% of weight) with a grain size under 1.00 mm were mixed with a clay to produce clay bricks by pressing, drying and then firing at 900°C. The results obtained demonstrate that an increase in the content of CW leads to a significant increase in apparent porosity of fired clay brick. The compressive strength and thermal conductivity of the samples decreased with the increase in content of (GCW).
