Performance Evaluation and Research of Versatile Cement Mortar with Rapid Strength Increase

Portland cement concrete is the world's most versatile and most used construction material. In order to meet the global demand for sustainability, civil engineers have looked to alternative supplementary cementitious materials (SCMs) such as fly ash to increase durability while lowering the initial and life-cycle cost. The objective of this study was to characterize the hardened concrete characteristics of cementitious compositions. Mechanical properties are the most important properties of hardened cementitious materials (cementitious materials with partial substitution by fly ash), therefore the research was primarily focused on compressive and tensile strength, bulk density, wear resistance and resistance against chemical environments.
