Abstract

Concrete roads encounter several durability issues that reduce their sustainability and increase their maintainable costs. Typical concrete durability solutions are formulated to lead a single functionality of waterproofing utilizing crystalline pore blocking or hydrophobic damproofing by creating a pore lining molecular layer. Each functionality can perform well in some durability parameters but cannot provide an integrated solution. The advancement of dual crystalline engineered (DCE) waterproofing material that integrate hygroscopic, hydrophilic and hydrophobic waterproofing functions in one liquid solution is shown to give a total durability solution to concrete roads. Several publications handled various aspects of DCE functionalities. This paper highlights the durability performance of DCE. It summarizes the reported results of durability parameters including permeability, water absorption, static water contact angle, ice adhesion, alkali silica reactions (ASR), chloride ion penetration, cycles of freezing and thawing, biological deterioration and mechanical properties.
