Technical focus
Areas of Expertise
Concrete performance is a system. Materials, proportions, production, testing, placement, curing, and exposure must be considered together.
Mixture proportioning
Balancing constituent materials, performance requirements, moisture corrections, production constraints, and verification data.
Concrete admixtures
Compatibility, dosage response, workability retention, setting behaviour, batching sequence, and interactions with cementitious systems.
Production quality control
Connecting material records, batching, delivery, sampling, specimens, testing, variability, nonconformity, and corrective action.
Fresh concrete
Workability loss, segregation, bleeding, temperature effects, transport, site adjustments, consolidation, and placement.
Hardened performance
Strength development, test variability, cracking, surface defects, permeability-related concerns, and performance verification.
Durability and repair decisions
Exposure, plausible deterioration mechanisms, investigation planning, repair-performance criteria, and limitations of available evidence.
Aggregates and moisture
Grading, density, absorption, moisture states, surface water, batch-water correction, and variability control.
Concrete testing
Purpose, method selection, sampling, specimen handling, comparability, acceptance context, and responsible interpretation.
How topics are handled
- Define the question and the decision to be supported.
- Identify the applicable project requirements and reference framework.
- Check whether the available records and test results are comparable.
- Separate observed facts, plausible mechanisms, assumptions, and unknowns.
- Define the trials, testing, approvals, or specialist assessment needed next.
