Selection of Repair Materials for Concrete Structures

Polymer Concrete Most popular polymer concrete used is an epoxy concrete system with curing agents or methyl methacrylate monomer with an inhibitor and promoter. Epoxy system is widely available in formulated repairing materials. This repair material can be customized as per the requirement for use in repair of different types of concrete damages.

Bioconcrete: next generation of self-healing concrete

The direct cost of crack repair and maintenance has been estimated at $147/m 3 of concrete, despite the fact that concrete production cost ranges between $65 and $80/m 3 (Silva et al. ). Therefore, preventive approaches to restrain and terminate crack formation at early stage are crucial.

Watertight Concrete System - Sika

Watertight Concrete System. Waterproof concrete is an impermeable concrete used for long-lasting, durable watertight construction. To improve the impermeability of the concrete, water-resisting admixtures can be added. Nevertheless, design and construction of a watertight concrete structure is a system approach, and waterproof concrete is only

INVESTIGATION INTO COMPATIBILITY BETWEEN REPAIR

In this dissertation the compatibility between eight repair materials and substrate concrete was investigated in three stages. First, individual properties of the repair materials such as setting time, flow, compressive strength, flexural strength, split tensile strength, bond strength, drying shrinkage, freeze-thaw resistance, and permeability

Compatibility of concrete repair materials and systems

Permeability compatibility In designing repair materials and systems consideration should be given to the permeability of the repair mater­ial relative to that of the substrate concrete. This is important not only from the perspective of chloride ion diffusion and electrochemical compatibility, but also with respect to the ability of the repair to breath.
