Early-age cement paste or mortar can be enhanced by curing it in a CO2 chamber. The study was initiated with investigation on the optimum compressive strength by replacing cement to carbide lime with 0, 5, 10, 15 and 20% of Carbide Lime Waste (CLW) content. The desired CLW mortar at 28 normal curing age was selected and the similar mix proportion was again casted and the fresh CLW mortar was cured for 1,3 and 7 days under controlled CO2 curing. The CO2 concentration and temperature were fixed at 20% and 60% respectively. The compressive strength and depth of carbonation of CLW mortar was investigated. In addition, their microstructural properties under TGA test was analysed at the early curing ages by using cement pastes. It was found that the mortar containing 5% of CLW had the desired optimum compressive strength and UPV under water curing condition. Overall, the strength properties of control mortar and CLW mortar significantly enhanced at early strength gained by controlled CO2 curing as compared to the water curing technique. The used of 5% of CLW as the potential to substitute the cement portion has provide better understanding on CO2 sequestration in cement mortar. The microstructural result shows the CaCO3 precipitation in the CLW mortar was higher than the control mortar as CLW has Ca(OH)2 behaviour which effectively react with CO2 and formed stable CaCO3 precipitation in the mortar.

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
