GOST 9179-77 PDF

Full title and description

GOST 9179-77 — "Известь строительная. Технические условия" (English: "Lime for building purposes. Specifications"). The standard defines technical requirements, classification, grades (sorts) and testing/acceptance rules for building lime produced by calcination of carbonate rocks or as a mixture with mineral additives; it covers forms such as lump (komovaya), powdered and hydrated (slaked) lime and distinguishes air and hydraulic limes.

Abstract

Interstate standard originally adopted in 1977 and introduced into force on 1 January 1979 that sets product definitions, classification by curing type, physical and chemical limits (active CaO+MgO, CO2, unburnt grains, slaking time, etc.), sampling and acceptance rules, marking and packaging requirements for construction lime used in mortars, plasters, and related building materials. The standard has been amended (Amendment No.1) and later superseded by a newer designation.

Scope

The standard applies to construction lime — the product of calcining carbonate rocks (or mixes with mineral additives) — intended for preparation of mortars, binders, concrete and building products. It defines types (air vs hydraulic), forms (lump, powdered, hydrated), quality grades (sorts), and the test/acceptance procedures necessary to ensure material performance in building practice. The standard was used across Soviet and successor-state industries until it was superseded.

Key topics and requirements

• Classification: air (calcareous, magnesian, dolomitic) and hydraulic limes; also by form — lump (komovaya), powdered, hydrated (slaked) and with/without mineral additives.
• Quality grades (sorts): typically 1st, 2nd and 3rd sorts with minimum active CaO+MgO content requirements (e.g., ~90%, ~80%, ~70% ranges for some product types) and specified limits for CO2, unburnt particles and moisture.
• Technical limits and tests: active oxide content, residual CO2, non‑slaked/unburnt grains, slaking time (fast/medium/slow categories), and other physico‑chemical criteria; sampling and batch acceptance rules (party sizes, weighing and documentation) are specified.
• Marking, packaging and storage: requirements for marking the product, recommended packaging (sacks, bulk, big bags) and dry storage to prevent premature hydration or quality loss.
• Use of additives: provisions for introduction of mineral additives (granulated slags, active mineral fillers) and rules for adjusting active CaO+MgO content when additives are present.

Typical use and users

Manufacturers of lime and lime‑based products, building materials producers (mortar, plaster, brickworks, autoclaved products), construction contractors, testing and quality control laboratories, technical regulators and procurement specialists. Typical applications include masonry mortars, plasters, soil stabilization, agricultural and sanitary uses, water treatment and metallurgical flux/reduction roles where construction lime grades are appropriate.

Related standards

Normative references cited in the standard include other GOSTs covering testing methods and raw materials (examples in the original document: ГОСТ 2226‑88, ГОСТ 6613‑86, ГОСТ 22688‑77 and others). The standard record shows it was later replaced by a modern revision designated ГОСТ 9179‑2018 (or the relevant current national/interstate replacement), which contains updated technical requirements and organization of clauses.

FAQ

Q: What is this standard?

A: GOST 9179-77 is a Soviet‑origin interstate standard titled "Известь строительная. Технические условия" (Lime for building purposes — specifications) that established classification, quality limits and acceptance/testing rules for construction lime.

Q: What does it cover?

A: It covers types of building lime (air and hydraulic), forms (lump, powdered, hydrated), quality grades (sorts), required physical and chemical properties (active oxide content, CO2, unburnt grains, slaking time), sampling/acceptance procedures, marking and packaging.

Q: Who typically uses it?

A: Producers of lime and lime‑based materials, construction material suppliers, testing laboratories, contractors specifying lime for mortars and plasters, and regulatory/standards bodies referencing binding requirements.

Q: Is it current or superseded?

A: The standard is listed as replaced/withdrawn in commercial and national registries; bibliographic records show it was active from 01.01.1979 and later restricted/withdrawn with a replacement standard indicated (ГОСТ 9179‑2018 or national equivalents). Users should consult the current national/interstate standard for up‑to‑date technical requirements.

Q: Is it part of a series?

A: It belongs to the family of standards for cement, gypsum, lime and mortars (ICS 91.100.10) and references other GOST documents for test methods and raw material requirements; it replaced parts of the earlier ГОСТ 9179‑70 in terms of technical conditions.

Q: What are the key keywords?

A: Lime, building lime, komovaya (lump), hydrated (slaked) lime, active CaO+MgO, CO2, slaking time, GOST 9179-77.
