GOST 30744-2001 PDF

Full title and description

GOST 30744-2001 — "Cements. Methods of testing with using polyfraction standard sand" (Рус.: "Цементы. Методы испытаний с использованием полифракционного песка"). The standard specifies laboratory procedures for preparing cement–sand mortars with a standardized polyfraction sand and for performing key physical tests (fineness, setting time, volume stability/soundness, compressive strength) used in quality control and certification.

Abstract

GOST 30744-2001 establishes a harmonized set of test methods that use a standardized polyfraction sand to assess properties of all types of cement. The methods are intended for routine production control, acceptance testing, and certification — including situations where supply or conformity is specified against EN 197-1. The standard defines sample preparation, mix proportions, specimen molding and curing, and required measuring equipment and verification.

Scope

This standard applies to all types of cement and specifies methods of testing cement properties using a standardized polyfraction sand as the aggregate for test mortars. It is intended for use in production and laboratory quality control, in certification procedures, and where contracts require conformity with EN 197-1 (the standard is referenced explicitly in the normative application notes).

Key topics and requirements

• Preparation of standard cement–sand mortar using polyfraction standard sand and prescribed proportions (example preparation proportions appear in the method — commonly cited recipe: 450 g cement: 1350 g polyfraction sand: 225 ml water for a single batch procedure).
• Determination of fineness (particle size / specific surface) of cement by prescribed laboratory sieving/assessment procedures.
• Measurement of setting times (initial and final) using standardized apparatus and test conditions.
• Assessment of volume stability (soundness / uniformity of volume change) according to specified procedures.
• Compressive strength testing of standard-cured mortar specimens (molding, curing regimes, and load application requirements).
• Requirements for test equipment, verification/calibration (including referencing ГОСТs for laboratory glassware and measuring instruments) and instructions for reporting test results.

Typical use and users

Primary users are cement manufacturers, factory and independent testing laboratories, certification and conformity assessment bodies, construction materials R&D groups, and procurement/contracting entities that require standardized comparative test data or conformity to EN 197-1. Laboratories use the standard daily for production control, acceptance sampling and certification tests.

Related standards

The standard references and works alongside other GOSTs and testing norms for laboratory instruments and materials (examples: ГОСТ 166-89 for calipers, ГОСТ 1770-74 for laboratory measuring glassware, and related cement testing GOSTs). It is specifically intended to be used where EN 197-1 is referenced in contracts; users should consult EN 197-1 and national/country-specific cement standards for regulatory alignment.

FAQ

Q: What is this standard?

A: GOST 30744-2001 is a Russian/Interstate standard that defines laboratory test methods for cements using a standardized polyfraction sand as the aggregate in mortar tests; it was introduced into force on 1 March 2002.

Q: What does it cover?

A: It covers preparation of standard cement–sand mortars, procedures for determining fineness, setting times, volume stability (soundness), compressive strength testing, and requirements for test equipment and reporting.

Q: Who typically uses it?

A: Cement producers, laboratory technicians, certification bodies, construction materials engineers, and purchasers who need standardized test results or require compliance with EN 197-1.

Q: Is it current or superseded?

A: As of the latest available normative-library entries, GOST 30744-2001 is listed as active (introduced in 2002) and has received amendments/notices in subsequent information bulletins; users should check an up-to-date national standards database for any more recent revisions or replacements before relying on it for regulatory compliance.

Q: Is it part of a series?

A: The document stands as a discrete GOST for cement testing with polyfraction sand but is related to other cement and testing GOSTs and normative references; it is used alongside EN 197-1 where that European standard is invoked by contract.

Q: What are the key keywords?

A: Cement testing, polyfraction sand, mortar preparation, fineness, setting time, soundness, compressive strength, EN 197-1, ГОСТ.
