Abstract

AbstractThe requirements on service life of reinforced concrete structures, as prescribed by design codes, may be difficult to be fulfilled in highly aggressive environments such as marine ones, in...

Highlights

  • During the last years, the civil and building engineering community has been paying increasing attention to the concept of sustainability, to the repair and conservation of reinforced concrete structures (Dossche et al 2016) to guarantee their strength and durability

  • Characterization of Self-Healing Based on Mechanical Properties: Compressive Strength The compressive strength of specimens made with both mixes and cured in different environmental conditions was investigated first

  • A slight decrease in compression strength was associated with the use of the crystalline admixture, coherently with what is known in the literature (Ferrara et al 2014)

Summary

Introduction

The civil and building engineering community has been paying increasing attention to the concept of sustainability, to the repair and conservation of reinforced concrete structures (Dossche et al 2016) to guarantee their strength and durability. The yearly global cost of repairing the degradation due to corrosion is estimated to be USD 2.5 trillion, which is equivalent to 3.4% of the global gross domestic product (GDP) (Koch et al 2016). These data indicate that the lack of corrosion management is very costly and that, by using proper corrosion control methods, significant savings on maintenance costs (about 15%–35%) could be obtained all along the service life of the reinforced concrete structure (Koch et al 2016)
