Rapid Chloride Penetration Test (RCPT).

Our Services

Evaluating Durability. Ensuring Longevity.

The Rapid Chloride Penetration Test (RCPT) is one of the most critical durability assessments for concrete, designed to measure its resistance to chloride ion penetration. This property directly influences the service life and corrosion resistance of reinforced concrete structures. Chloride ions, often introduced from the surrounding environment, can lead to steel reinforcement corrosion — one of the most common causes of premature concrete deterioration. The RCPT provides a quick, accurate, and reliable indication of how well your concrete can withstand such chloride ingress

Why RCPTMatters.

Predicts corrosion risk

Chloride ions reaching steel cause corrosion — RCPT gives a rapid, quantitative indication of that risk.

Informs material selection

Compare mixes, SCMs (fly ash, slag, silica fume), or admixtures for chloride resistance.

Supports lifecycle decisions

Optimize maintenance, cathodic protection schedules, and service-life models.

Critical for exposed structures

Airports, Dams, Coastal, marine, bridges, parking decks, and de-iced roads.
