Reinventing concrete: exploring strength and durability with portland slag cement

Abstract

The potential of Portland Slag Cement (PSC) may increase mechanical strength and longevity, its application in concrete is becoming more and more popular. PSC-concrete qualities are examined in this work, with a particular emphasis on microstructure, strength, and durability. Compressive, split tensile, flexural, and modulus of elasticity tests were conducted using different curing techniques. The outcomes were contrasted with formulations of regular Portland cement (OPC). At various curing times, tests for durability such as porosity, acid resistance, sorptivity, water absorption, and chloride penetration were carried out. PSC-related microstructure alterations were examined using sophisticated methods including SEM and XRD. Results show that PSC enhances concrete performance over the short and long terms, especially in abrasive settings. Microstructural research reveals that the effect of slag is responsible for improved pozzolanic reactions, decreased porosity, and refined pore structure. The potential of PSC to improve the lifetime and durability of concrete is highlighted by this study.
