    (Springer Nature, 2025-04-05) Nahla Hilal; Abdulkader I. Al-Hadithi; Jamal A. Khalaf; Farah A. Al-Fahdawi; Zouaoui R. Harrat; Taher A. Tawfik
    This study aimed to identify the optimal ratio of polyethylene terephthalate (PET) fibers to enhance the structural performance of ferrocement slabs, particularly under varying high-temperature conditions. The research examines the effects of PET fibers on the hardened properties of ferrocement mortar, as well as how both PET fibers and elevated temperatures (25 °C, 100 °C, 200 °C, 400 °C, and 600 °C) influence the impact and mechanical behavior of the material. To achieve this, four volumetric proportions of PET fibers (0%, 0.5%, 0.75%, and 1%) were first used to identify the optimum PET content, which was found to be 0.75%. The impact and mechanical behavior of ferrocement slabs were then investigated using the optimized mix. To evaluate the impact behavior, a total of 25 two-way slabs of 500 mm × 500 mm × 50 mm were prepared and tested. The parameters were (a) fiber content (0% and 0.75%), (b) layers of steel wire mesh reinforcement (0, 2, and 4 layers), and (c) elevated temperatures (25 °C, 100 °C, 200 °C, 400 °C, and 600 °C). These were organized to have five different slab configurations: zero reinforcement layer (0L) and zero fiber (0F) (0L-0F); 2L-0F, 4L-0F, 2L-0.75F, and 4L-0.75F. Each of these slabs was tested under the five selected elevated temperatures, making the 25 specimens needed. The same parameters were repeated to evaluate the flexural behavior of ferrocement slabs using 25 one-way slabs with dimensions of 1200 mm × 150 mm × 50 mm. The results indicated that PET fibers decreased density and ultrasonic pulse velocity while increasing water absorption. At a PET fiber content of 0.75%, the compressive and flexural strengths increased by 17.85% and 5.79%, respectively, after 28 days. Strength loss was minimal up to 200 °C, but significant reductions were observed beyond 400 °C. The optimal performance was found in slabs with 0.75% PET and two layers of reinforcement at 200 °C, displaying improved flexural strength, toughness, and ductility. At 600 °C, the breakdown of the plastic fibers resulted in a substantial performance decline. Overall, the findings show that PET fibers enhance ferrocement performance up to 400 °C but experience degradation at higher temperatures.

    Durability and hardened characteristics of cement mortar incorporating waste plastic and Polypropylene exposed to MgSO 4 attack
    (Elsevier, 2024-12) Nahla Hilal; Osamah Mohammed G. Al-Kerttani; Sheelan Mahmoud Hama; Nadhim Hamah Sor; Qais Sahib Banyhussan; Taher A. Tawfik
    Annual waste plastic disposal has grown, harming nature. Utilising this waste in concrete production may help preserve building resources. This study tested cement mortar with polyvinyl chloride (PVC) and polypropylene (PP) substituted for sand aggregate at 0, 5, 10, 15, and 20 %. The samples were nevertheless exposed to a 10 % and 20 % MgSO4 solution for a month. The properties of both fresh and hardened materials under these cir cumstances have been evaluated and contrasted with those evaluated under typical circumstances. For mixes including PP and PVC, the flow diameter increased. The rounded plastic particles provided fewer contact surfaces and less friction among mixtures, which reduced water consumption and improved workability, leading to an increase in slump flow. As the amount of plastic aggregate increases, the compressive strength decreased. Moreover, this pattern might be explained by the weakening of the bond between the surfaces of the plastic aggregate and cement paste. The hydration of cement may also be hampered by the hydrophobic properties of plastic aggregate. Like compressive strength, the splitting tensile strength decreased as the replacement level of plastic ratio increased regardless of its type under all conditions (normal and exposing to MgSO4 ). PP and PVC fine aggregate in mortar increases sorptivity under all situations. Following screening, those circumstances and PVC have the most impact on compressive strength. increasing PVC and PP at 10 % for each of them leads to lower values of compressive and tensile strength. An optimization process was implemented to determine the optimum value of PVC, PP, and MgSO4 . It shows that using PVC of 3.9 %, PP of 10.1 %, and MgSO4 leads to maximum compressive and tensile strength with the minimum cost and CO2 emissions.

    Studying the usability of recycled aggregate to produce new concrete
    (Faculty of Engineering, Cairo University (CUFE), 2024-06-11) Nahla Hilal; Ola Adel Qasim; Mohammad I. Al Biajawi; Nadhim Hamah Sor; Taher A. Tawfik
    One of the most significant environmental issues worldwide is garbage, particularly waste from construction materials, which is generated in substantial numbers. How ever, in the building industry, the significant extraction of natural resources such as cement, natural sand, and natural gravel poses a critical environmental challenge, depleting these resources at an alarming rate. There are some solutions that devel oped countries are resorting to, namely the division of construction waste into groups, where it is reused under the name of recycling construction waste to produce new, environmentally friendly building materials. The aim of this research includes a labora tory process study as it includes the use of the following ratios: 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100%, under the process of replacing coarse plain aggregates includ ing coarse recycled aggregates and studying the most important mechanical proper ties of concrete. This research was carried out using fresh concrete properties such as workability tests and hardened concrete properties such as compressive strength, splitting, and flexural tensile strength examined at the durations of 7, 14, and 28 days. The research includes the investigation of the three main properties of concrete. After conducting the tests, the results have shown that the main property of recycled concrete is lower strength than that of conventional concrete, but it can be said that it is within the limits that can be used for construction. The results also showed that com pared to normal aggregates, development in the recycled aggregate percentage rates reduces the operational workability of concrete. The research proved that the maxi mum decrease in compressive, flexural, and tensile strength, density and the slump were 19.4, 18.3, 19.6, 19.5, and 25.0% respectively compared to the control concrete samples.

    The influence of nanosunflower ash and nanowalnut shell ash on sustainable lightweight self‑compacting concrete characteristics
    (Springer Nature, 2024-04-24) Nahla Hilal; Nadhim Hamah Sor; , Marijana Hadzima‑Nyarko; Dorin Radu; Taher A. Tawfik
    The absence of biodegradability exhibited by plastics is a matter of significant concern among environmentalists and scientists on a global scale. Therefore, it is essential to figure out potential pathways for the use of recycled plastics. The prospective applications of its utilisation in concrete are noteworthy. The use of recycled plastic into concrete, either as a partial or complete substitution for natural aggregates, addresses the issue of its proper disposal besides contributing to the preservation of natural aggregate resources. Furthermore, the use of agricultural wastes has been regarded as a very promising waste-based substance in the industry of concrete manufacturing, with the aim of fostering the creation of an environmentally sustainable construction material. This paper illustrates the impact of nano sunflower ash (NSFA) and nano walnut shells ash (NWSA) on durability (compressive strength and density after exposure to 800 °C and sulphate attack), mechanical properties (flexural, splitting tensile and compressive strength) and fresh characteristics (slump flow diameter, T50, V-funnel flow time, L-box height ratio, segregation resistance and density) of lightweight self-compacting concrete (LWSCC). The waste walnut shells and local Iraqi sunflower were calcinated at 700 ± 50 °C for 2 h and milled for 3 h using ball milling for producing NSFA and NWSA. The ball milling succeeded in reducing the particle size lower than 75 nm for NSFA and NWSA. The preparation of seven LWSCC concrete mixes was carried out to obtain a control mix, three mixtures were created using 10%, 20% and 30% NWSA, and the other three mixtures included 10%, 20% and 30% NSFA. The normal weight coarse aggregates were substituted by the plastic waste lightweight coarse aggregate with a ratio of 75%. The fresh LWSCC passing capacity, segregation resistance, and filling capability were evaluated. The hardened characteristics of LWSCC were evaluated by determining the flexural and splitting tensile strength at 7, 14 and 28 days and the compressive strength was measured at 7, 14, 28 and 60 days. Dry density and compressive strength were measured after exposing mixes to a temperature of 800 °C for 3 h and immersed in 10% magnesium sulphate attack. The results demonstrated that the LWSCC mechanical characteristics were reduced when the percentages of NWSA and NSFA increased, except for 10% NWSA substitution ratio which had an increase in splitting tensile strength test and similar flexural strength test to the control mixture. A minor change in mechanical characteristics was observed within the results of LWSCC dry density and compressive strength incorporating various NSFA and NWSA` contents after exposing to temperature 800 °C and immersed in 10% magnesium sulphate attack. Furthermore, according to the findings, it is possible to use a combination of materials consisting of 10–20% NSFA and 10–20% NWSA to produce LWSCC.

    Durability and Hardened Characteristics with SEM Analysis of Eco‑Efficient Self‑Compacting Concrete Partially Contained Waste Walnut Shell Particles as Fine Aggregate
    (Springer Nature, 2023-07-23) Nahla Hilal; Hadi H. Edan; Nadhim Hamah Sor; Taher A. Tawfik
    Substituting waste materials for natural aggregate in SCC can lead to the discovery of ecological building materials. Walnut shell (WS) is one of the agricultural byproducts that can be substituted for aggregate in SCC. In this study, WS was used as a replacement for fine aggregate in SCC by employing five different volume fractions ranging from 8 to 40% in incre ments of 8% while maintaining a constant percentage of limestone powder (10% by weight of cement). All SCC mixtures were evaluated for the fresh properties (slump flow, slump flow duration, V-funnel, L-box, and wet density) tests, hardened characteristics (compressive strength, splitting tensile strength, flexural strength, Schmidt rebound hammer, and ultrasonic pulse velocity) tests, scanning electron microscopy (SEM) analysis, and the effect of H2SO4 and MgSO4 solution with 5% concentration for one month period on the density, compressive and splitting tensile strengths. The hardened properties were performed at 28 and 56 curing periods. The results revealed that the workability and hardened properties of SCC mixtures decreased with increasing WS content, but the workability outcomes were within the standard specifications of SCC, except for the L-box test. The lowest compressive strength of 23.7 MPa was recorded for the mix containing 40% of WS, greater than the lower strength required for structural purposes. On the other hand, the density, compressive and splitting tensile strengths of all SCC mixes decreased after exposure period for both sulphate attacks. The investigation with SEM reveals that the increasing amount of WS produced more voids and less dense concrete compared to the control mix.
