Full title and description

GOST 17624-2012 — Concrete. Ultrasonic method of strength determination. The standard specifies the ultrasonic pulse (impulse) method for assessing the compressive strength of heavy and light structural concretes in monolithic and precast concrete and reinforced‑concrete elements and structures.

Abstract

GOST 17624-2012 defines procedures for measuring ultrasonic pulse velocity in concrete and for using those measurements to estimate in-situ compressive strength. It describes required instrumentation, measurement locations and patterns, data processing and correlation with core/specimen test results, and references related normative methods for control and evaluation of concrete strength. The standard was adopted for application in the Russian Federation and entered into force for national use by Rosstandart directives.

• Publisher: Adopted as an interstate / national standard under the authority of the Federal Agency on Technical Regulating and Metrology (Rosstandart) and published in official collections and commercial standards catalogues.
• ICS / categories: 91.100.30 (Construction materials and building — Concrete and concrete products).
• Edition / version: Edition: 2012 (GOST 17624-2012). A later revision was released as GOST 17624-2021.
• Number of pages: Approx. 20–21 pages in published commercial copies of the 2012 edition (page counts reported vary slightly by publisher/format).

Scope

The standard applies to structural heavy and light concretes in monolithic and precast concrete and reinforced‑concrete products, structures and assemblies. It establishes the ultrasonic pulse (impulse) nondestructive testing method for estimating compressive strength of concrete in-place and provides procedures to correlate ultrasonic measurements with laboratory specimen/core strength results. It is intended for use as a complementary or screening method alongside core testing and other control methods referenced in national practice.

Key topics and requirements

• Definition of the ultrasonic pulse (impulse) method for concrete strength estimation (measurement of pulse transit time and pulse velocity).
• Instrument requirements, transducer types and frequency ranges, coupling methods and calibration recommendations.
• Specimen and in-situ measurement procedures: selection of measurement points, path lengths, and transducer positioning.
• Data processing and calculation of pulse velocity; correlation approaches linking pulse velocity to compressive strength (including the need for local calibration with cores or standard specimens).
• Acceptance and reporting formats, measurement uncertainty considerations, and limitations of the method (influence of moisture, temperature, reinforcement, and heterogeneity).
• Normative references and cross-references to specimen-based strength testing standards (for example, standards for laboratory compressive strength tests that are used when correlating ultrasonic data).

Typical use and users

Used by civil/construction engineers, materials and quality-control laboratories, inspection bodies, contractors and asset owners for nondestructive evaluation and screening of concrete strength in structures, precast elements and during repair/assessment works. Typical applications include site quality control, pre-demolition surveys, condition assessment of existing structures and as part of combined NDT/core testing programs.

FAQ

Q: What is this standard?

A: GOST 17624-2012 is a national/interstate standard that specifies the ultrasonic pulse (impulse) method for determining the compressive strength of concrete in structures and precast elements.

Q: What does it cover?

A: It covers measurement procedures, instrumentation and transducer guidance, recommended measurement patterns, data processing and correlations to estimate compressive strength from pulse velocity, plus requirements for reporting and limitations of the method.

Q: Who typically uses it?

A: Engineers, materials laboratories, inspection and testing organizations, contractors and owners who perform concrete quality control, condition assessment and nondestructive testing.

Q: Is it current or superseded?

A: The 2012 edition has been superseded by a later revision published as GOST 17624-2021; users should refer to the 2021 text for the current national requirements. Commercial and national catalogues and the standards registry list the 2021 revision as the active document.
