Stop Repairing Leaks. Start Engineering Self-Healing Concrete.

The definitive 25-chapter engineering manual, absolute volume mix design tools, executable Python transport solvers, and CSI MasterFormat™ specifications for materials engineers, structural consultants, and infrastructure owners.

 

The Infrastructure Durability Crisis

Civil infrastructure is trapped in an expensive reactive repair cycle. Concrete is the most consumed man-made material on Earth, yet its quasi-brittle nature guarantees micro-cracking under tensile stress, thermal gradients, and drying shrinkage.

When micro-cracks (w>50μm) form, they bypass dense concrete cover, establishing high-velocity fluid conduits. Water, chloride ions, sulfates, and carbon dioxide penetrate to the depth of reinforcing steel, initiating depassivation, active corrosion, and structural spalling.

The traditional response? High-pressure polyurethane injection, surface silane sealing, and hydrodemolition patching.

• The Problem: Reactive repairs fail within 5 to 10 years due to thermal expansion mismatch and interfacial debonding.

• The Cost: Municipalities and private owners spend up to 50% of annual capital budgets on recurring repairs.

• The Structural Risk: Subterranean subway tunnels, marine port caissons, and deep foundations are physically inaccessible for manual repair once placed.

The Solution: Autonomous Bio-Autonomic Resilience

Self-Healing Concrete Systems: Design Mixes & Field Manual provides the scientific formulations, absolute volume mathematical models, ready-mix batching sequences, and job-site QA/QC protocols required to transition concrete from a passive, deteriorating composite into an autonomic, self-repairing system.

By integrating alkaliphilic bacterial endospores (Bacillus pseudofirmus, Pseudomonas pseudoflava), organic calcium nutrients, polymeric microcapsules, and high-ductility short synthetic fibers, this field manual enables you to engineer concrete matrices that automatically seal micro-cracks (w≤250μm) within days of formation—restoring fluid tightness (HEQ≥95%) and extending structural service life past 100 years.
