Full title and description

O’z DSt 761-96 — "Portland cement, white. Technical specifications" (Портландцементы белые. Технические условия). This national standard defines technical requirements, quality classes and testing/marking/packaging rules for white Portland cement produced and certified in the Republic of Uzbekistan.

Abstract

This standard specifies composition, physical and chemical properties, strength classes, acceptance and test methods, packing, marking and storage requirements applicable to white Portland cement (used for decorative and demanding construction applications where colour and whiteness are important). It is the national Uzbek state standard referenced by producers and suppliers of white Portland cement in Uzbekistan.

Scope

O’z DSt 761-96 applies to white Portland cements intended for general construction and decorative use where colour/whiteness and specific physical properties are required. The standard covers technical requirements for raw materials and clinker, chemical composition limits, physical properties (fineness, setting time, soundness), strength classes, sampling and test methods, rules for acceptance, packaging, marking and storage. It is intended for manufacturers, testing laboratories and conformity assessment bodies operating under Uzbekistan’s national standardization system.

Key topics and requirements

• Definition and classification of white Portland cement grades/strength classes (e.g., designations equivalent to PCB / ПЦБ types used in regional product descriptions).
• Chemical composition limits to assure whiteness and performance (control of iron and other colouring impurities).
• Physical requirements: fineness, specific surface, initial and final setting times, soundness (expansion), and compressive strength test criteria at specified ages.
• Sampling, test methods and measurement procedures for quality control and acceptance testing.
• Packing, marking and storage requirements including recommended bag types and net weight marking (typical commercial packing — 50 kg bags or bulk deliveries).
• Conformity assessment and documentation required for shipment and trade (manufacturer’s certificate, test reports, marking information).

Typical use and users

Primary users are cement manufacturers, concrete and dry-mix producers, precast and architectural concrete manufacturers, construction contractors and testing laboratories. Typical applications include decorative white concrete, terrazzo, architectural finishes, reprographic concrete elements, and any construction works where white colouring and predictable physical performance are required. Product listings and manufacturer datasheets in the region reference O’z DSt 761-96 as the governing specification.

Related standards

O’z DSt 761-96 is a national standard in the O’z DSt series and sits alongside related cement standards such as O’z DSt 762-96 (coloured Portland cement) and regional/inherited GOST standards formerly applied to cement (historic references note replacement of or alignment with earlier GOST documents such as GOST 965-89 in some contexts). For laboratory methods and wider cement/aggregate testing, relevant ICS/ISO and GOST test-method standards are typically used in conjunction.

FAQ

Q: What is this standard?

A: O’z DSt 761-96 is the Uzbek national standard titled "Portland cement, white. Technical specifications" that sets technical, testing and conformity requirements for white Portland cement produced and supplied in Uzbekistan.

Q: What does it cover?

A: It covers raw-material and clinker requirements relevant to white cement, chemical and physical property limits (including whiteness-related impurities), strength classes, sampling and test procedures, acceptance rules, packing, marking and storage. It therefore defines both product and quality-control requirements for white Portland cement.

Q: Who typically uses it?

A: Cement producers, suppliers, concrete and dry-mix manufacturers, construction contractors, testing and certification laboratories, and regulatory/market surveillance bodies in Uzbekistan and regional markets where O’z DSt standards are applied.

Q: Is it current or superseded?

A: Catalogue listings show O’z DSt 761-96 as an active document in standard text databases and reseller catalogues; however, users should verify with the national standards body or official national catalogue for any amendments or superseding documents before relying on it for regulatory compliance or procurement.

Q: Is it part of a series?

A: Yes — it is part of the O’z DSt national standards series for construction materials; related numbers in the same 1996 family include nearby cement and construction-material standards (for example O’z DSt 762-96 for coloured Portland cement). National O’z DSt numbers commonly group related technical documents.

Q: What are the key keywords?

A: White Portland cement, technical specification, O’z DSt 761-96, PCB, whiteness, compressive strength, cement testing, packaging, national standard.
