Durability Properties of Rigid Pavement Quality Concrete Containing Ground Granulated Slag

Abstract

Based on the cost and durable characteristics, ground granulated slag was chosen. Pollution in the environment can also be reduced by limiting the entry of carbon dioxide and other harmful gases into the atmosphere. The current work is mainly associated with evolution of changes in compressive strength and weight loss in 4 different mixes of M20 grade concretes namely conventional concrete (CC), concrete replaced by 1% polypropylene fiber by weight of cement (CC+1%PPF), total replacement of cement by slag along with (KOH and K₂SiO₃) solution (AASC) and total replacement of cement by slag along with (KOH and K₂SiO₃) solution with 1% polypropylene fiber (AASC+1%PPF). 14M KOH and K₂SiO₃ are considered to project AASC blends. Starter examination has investigated blends with various soluble base activator modulus at variable potassium oxide measurements. Higher qualities are obtained with a 5 percent oxide content and 1.25 MR. An expansion in potassium oxide measurements past 5% lessens strength boundaries. The effect of 0.3% and 1% of H₂SO₄ and MgSO₄ on the above concrete mixes (cubes) were immersed in solutions for 14, 28, 56, and 91 days and their behaviours are examined. Based on the results obtained, alkali-activated slag concrete with 1% polypropylene fiber is found to achieve high strength and low weight loss.
