dc.description.abstractLimestone powder (LP), derived from marble dust and stone waste, was utilized as a sand substitute in engineering cement compounds (ECC). This readily available material is a by-product of industrial waste from local quarries and stone cutting, and it was sourced from Mosul factories for this research. The study aimed to fully replace the fine aggregate in ECC with LP. Experimental findings demonstrated that LP had an impact on the hardening and drying process, resulting in longer drying and hardening times. Consequently, there was a decrease in the initial compressive and tensile strength. However, the use of finer LP compensated for this effect. Seven mixtures were tested with varying LP/PC (Portland Cement) replacement ratios (0.75, 1, 1.5, 2, 2.5, 3, and 3.5). The best results were obtained with mixture M5. The addition of LP led to an increase in compressive strength, with values reaching up to 32.40 MPa at 28 days. Finer LP particles further enhanced this effect. Conversely, increasing the LP/PC replacement ratio resulted in a reduction in tensile strength due to the higher water-cement ratio. The tempering effect contributed to an enhancement of 3.92 MPa in tensile strength. The incorporation of LP significantly reduced the environmental impact by decreasing the demand for natural resources. The use of limestone in the ECC mortar gave good results for tests of the mechanical properties of the mortar, as this is considered a viable option for use in building, construction, and repair operations. It is recommended that further improvements, research, and studies be conducted to improve the formulations and types of such alternative mortar.
