Alkali-Silica Reactivity Test Services

Evaluation, Mitigation and Monitoring

CTLGroup is at the forefront of managing alkali-silica reaction in concrete structures. Alkali-silica reaction (ASR) is a physico-chemical reaction that can lead to premature deterioration and shortened service life.

Since the discovery of alkali-silica reaction in concrete during the early 1940s, CTLGroup scientists and engineers have been industry leaders in ASR detection, identification, mitigation and testing. Our portfolio includes work on many projects, specifications, test methods, rehabilitation techniques and handbooks noted throughout the industry.

We offer clients in a broad range of industries, including nuclear, a full in-house approach, from initial diagnosis and evaluation of the structure all the way through the repair and long-term monitoring of the repair.

Our approach to alkali-silica reactivity testing includes three phases:

  • Phase 1: Diagnosis & Evaluation
  • Phase 2: Mitigation, Repair & Instrumentation
  • Phase 3: Long-term Monitoring

CTLGroup’s Quality Management System is NQA-1 compliant, which demonstrates our commitment to delivering laboratory and consulting services that meet the rigorous quality demands required by many industries, such as commercial nuclear energy.
