“…Results revealed that 15% porcelain waste folded better performance compared to the control mix in terms of compressive and flexural strength, sorptivity, corrosion and chloride penetration as well as achieved major environmental benefits. Similar findings were recorded by Hasan et al [29] when replacing the sand with 20% porcelain waste.…”

Among all the concrete characteristics, the compressive strength is known as the most important feature and therefore, it is often utilized to quantify the quality of concretes. The assessment of concretes strength in existing constructions is important during their service life. Thus, in addition to destructive evaluation of strength, many non-destructive techniques have been adopted to assess the concretes strength. Ultrasonic Pulse Velocity (UPV) is one of the nondestructive techniques that involve measuring the speed of ultrasonic wave through concretes to predict concretes strength. According to the Griffith's theory, the strength of the material is greatly affected by the defects' existence (for example, small cracks). These cracks can be current prior to the application of any loading or could create throughout the load application. The presence of micro-cracks in concretes that generate due to the applied load may affect the UPV test results in comparison with unloaded concretes. An experimental investigation is conducted in order to assess the impact of the applied of load (ultimate load) on the measured ultrasonic wave velocity and compared with the results of compressive strength from destructive test. A total of thirty (150 mmx150mm) cube specimens have been utilized with water to cement ratios (0.45). These cubes have been examined in ultrasound without any loads and then they have been tested in the same way with applied ultimate load which is approximately equal to half of the required design load (failure load) and then inspected or tested in the normal way (destructive test). In order to assess the compressive strength of concretes using (UPV), loading condition is considered in order to study the impact of the applying load. In addition, the water absorption has been examined for thirty concretes samples under the impact of the applied loads (20%, 40% and 60%). The results of nondestructive tests of concretes samples under the influence of imposed loads (60%) have showed to be less by compressive strength 5 MPa than the results obtained from testing of unloaded concretes samples through the resulting equation and comparing them to the equation from previous research. This is consistent with the water absorption test of the specimens under the imposed loads (60%) where Absorption values have been greater than concretes models without applied loads. Copyright

“…The use of such recyclable materials in construction is considered eco-friendly and appropriate to reduce serious problems such as nonbiodegradability, accumulation of wastes, and protect natural resources from consumption. On the other hand that would open the field forwards the researchers to explore the desirable produced characteristics and the limitations [1][2][3][4][5].…”

“…Glass waste is categorized as a nonbiodegradable residual solid, an alternative solution to avoid its accumulation in landfills is to use it in construction as a minimal to mitigate this serious environmental problem [2]. In the United States in (2015), glass generation was 11.5 million tons, whereas approximately 7 million tons of waste of glass was received in landfills only in that year [14].…”

The present study involved assessing the replacement of fine aggregate in the mortar with sustainable local materials like clay bricks and glass included 168 specimens (cubes and prisms). Seven mixtures were cast for this work, one control mix (R1) with 100% natural sand whereas mixes from R2 to R5 have 10% and 20% replacing natural sand with waste clay bricks and waste glass separately and respectively. Mix R6 was included 20% replacing sand with combination waste materials (10% waste clay bricks with 10% waste glass). Mix R7 has involved the same percent of replacing the previous mix R6 but with adding Polypropylene fibers 1% by volume. The samples have put in an electrical oven for one hour at 200, 400, and 600 ᵒC then cooled to room temperature to be tested and compared with samples at normal temperature 24 ᵒC. Different mechanical tests were adopted involved flow tests, density, weight loss, compressive strength, flexural strength, and water absorption. The results at different temperatures were discussed where many findings were specified. The flexural strength at 400 ᵒC was showed improving by 56% for 20% waste clay brick and 69% with 10% waste glass, as well all combination mixes illustrated higher strength than the control.
