GOST 31359-2007 PDF

Full title and description

GOST 31359-2007 — "Бетоны ячеистые автоклавного твердения. Технические условия" (English: "Cellular autoclave curing concretes. Specifications"). The standard sets technical requirements, marking, test methods and quality control rules for autoclaved (steam-cured) cellular concretes used to manufacture blocks, panels, lintels and other products.

Abstract

This interstate GOST defines classification (by purpose and porosity method), density and strength grades, production and autoclave-curing requirements, sampling and laboratory test methods (density, compressive strength, moisture, frost resistance, dimensional tolerances), and provisions for safety (combustibility, radioactivity) and conformity assessment for autoclaved cellular concretes (AAC and related materials). It was developed by specialized institutes and industry experts and intended for manufacturers, test laboratories and regulators.

General information

• Status: Replaced / superseded (listed as replaced by a 2024 edition in national registries; earlier databases also show withdrawn/obsolete status).
• Publication date: Designation year 2007; introduced into force 1 January 2009 (common entry-into-force date in bibliographic records).
• Publisher: Adopted as an interstate GOST by the Interstate Council for Standardization, Metrology and Certification (EASC / МГС). (Developed with participation of construction research institutes such as NIIZHБ and other organizations.)
• ICS / categories: 91.100.30 — Concrete and concrete products.
• Edition / version: ГОСТ 31359-2007 (original designation); later recorded as replaced by GOST 31359-2024 in some national registries.
• Number of pages: Typically published around 15 pages in the standard text (commercial copies list 15–19 pages depending on formatting).

Scope

This standard applies to autoclaved cellular concretes intended for production of construction products (blocks, wall and floor panels, lintels, etc.). It establishes terminology, classification by intended use (structural, structural-thermal-insulating, thermal-insulating), density and strength markings, technical requirements for raw materials and produced items, test procedures for key properties (average density, compressive strength, moisture, frost resistance), and rules for acceptance and quality control. It is intended for use in standardization, product specifications and regulatory documents for AAC products.

Key topics and requirements

• Classification of cellular concretes by purpose (structural, structural-thermal, thermal-insulating) and by pore-formation method (gas, foam, gas-foam).
• Density grades (common D‑class system, e.g., D200–D1200) and corresponding strength/usage limits.
• Requirements for raw materials, mix design, autoclave curing regime and manufacturing documentation.
• Test methods and sampling rules for average density, compressive strength (reference to ГОСТ procedures), moisture conditioning and determination of frost resistance.
• Dimensional tolerances, marking and labelling requirements for products.
• Safety and conformity checks: combustibility classification, limits on natural radioactivity and other sanitary/technical safety notes.

Typical use and users

Primary users are AAC and cellular concrete manufacturers, product designers and structural engineers specifying masonry and panel systems, testing and certification laboratories, construction quality inspectors, procurement specialists and regulatory authorities responsible for building materials. The standard is applied when developing product technical specifications, production quality systems and acceptance testing protocols for autoclaved cellular concrete items.

Related standards

GOST 31359-2007 cross-references and is used alongside other standards for cellular concretes and testing methods, for example: GOST 25485 (cellular concretes), GOST 27005 (rules for average density control), GOST 18105 (strength classes), GOST 12730 series (testing of concrete), GOST 30244 (flammability), and later national/international documents that update test procedures or product classes. The 2007 edition has been cited and later replaced within a family of updated norms (e.g., GOST 31359-2024).

FAQ

Q: What is this standard?

A: An interstate GOST that sets technical specifications for autoclaved (steam-cured) cellular concretes — products commonly known as autoclaved aerated concrete (AAC) or related cellular concrete materials. It covers requirements for manufacture, marking and testing.

Q: What does it cover?

A: Classification by purpose and porosity method, density and strength grades, requirements for raw materials and production (including autoclaving), sampling and laboratory tests (density, strength, moisture, frost resistance), dimensional tolerances, marking, and safety checks (combustibility, radioactivity).

Q: Who typically uses it?

A: Manufacturers of AAC and cellular concrete products, test laboratories, construction designers and engineers, quality inspectors, certification bodies and regulators involved in building-materials compliance.

Q: Is it current or superseded?

A: The 2007 designation (ГОСТ 31359-2007) has been recorded in multiple bibliographic sources and was introduced into force around 1 January 2009; registry entries and standards catalogs indicate it has later been replaced/superseded by a 2024 edition (GOST 31359-2024) in some national registries. Users should consult the latest national or interstate catalogues to confirm the currently active edition before applying the norm.

Q: Is it part of a series?

A: It belongs to the set of standards governing cellular and lightweight concretes and references several related GOSTs for test methods and material properties; it is part of the broader regulatory framework for concrete products and construction materials.

Q: What are the key keywords?

A: Autoclaved cellular concrete, aerated concrete, cellular concrete, autoclave curing, density class, compressive strength, frost resistance, test methods, ГОСТ 31359.
