Performance analysis of ordinary portland cement and portland pozzolan cement cement in improving sea sand and sea water concrete with zeolite powder

Year: 2025

Type: article

Abstract: This study examines the performance of concrete made with sea sand sea water using two types of cement: ordinary portland cement (OPC) and portland pozzolan cement (PPC), with the incorporation of zeolite powder.Variations in zeolite content (0%, 7.5%, and 10%) were tested to evaluate compressive strength at 14, 28, and 56 days, as well as durability after immersion in a 5% Na₂SO₄ solution for 30, 60, and 90 days.The results indicate that OPC-based concrete generally achieves higher compressive strength compared to PPC.The addition of 7.5% zeolite to OPC yielded optimal compressive strength at 56 days, while PPC with 10% zeolite demonstrated significant improvements, despite lower overall strength.Durability testing revealed that PPC concrete exhibited superior resistance to aggressive environments, particularly sulfate attack.The addition of 10% zeolite significantly enhanced durability up to 90 days of immersion.For OPC concrete, 7.5% zeolite effectively reduced porosity and improved durability, although a slight decline was observed at 90 days.These findings highlight that while OPC provides better compressive strength, PPC with zeolite offers superior durability under harsh environmental conditions, making it a recommended choice for concrete construction in coastal regions.
