Performance Analysis of High-Strength, Self-Consolidating Concrete with Supplementary Cementitious Materials for Enhanced Durability in Marine Structures

Abstract

1.1 Background.Coastal engineering structures including bridge, offshore platforms, seawalls and retaining structures are important structures that are used in the
marine environment to support socio economic activities. But their durability and service life are threatened by these aggressive and severe marine environment
conditions on those structures continuously. Chemical processes like chloride penetration, sulfate attack, carbonation, freeze-thaw cycle, and the cycle of wet-dry
deteriorated concrete still stands for construction of such structures. This leads to compromise of structure, durability, and increased maintenance cost of the related
infrastructure (Mehta & Monteiro, 2014).
Achievement of sustainability objectives is also enhanced through the use of SCMs since they give solutions to the reduced use of OPC which you know releases
CO₂ during production. According to Gartner and Hirao, 2015, SCMs can incorporate up to 50% of the cement within a concrete mix, remarkably reducing the
emission of carbon during construction processes. Furthermore, most of the SCMs are industrial waste products which include fly ash from coal power plants and
steel slag, thus supporting waste management and the circular economy (Zhang et al., 2020).
