ASTM D1632-17e1 PDF

Full title and description

ASTM D1632-17e1 — Standard Practice for Making and Curing Soil‑Cement Compression and Flexure Test Specimens in the Laboratory. This practice provides procedures for preparing, compacting, molding, and curing laboratory soil‑cement specimens intended for compressive and flexural strength testing under controlled conditions.

Abstract

This standard practice describes the step‑by‑step methods to make and cure soil‑cement test specimens used for compressive and flexural testing. It defines specimen dimensions, molding and compaction procedures, curing environments and durations, and references applicable test methods for subsequent strength testing. The practice ensures reproducible specimen preparation to produce comparable strength data for mix design, quality control and research.

Scope

The practice covers procedures for making and curing compression and flexure test specimens of soil‑cement in the laboratory under accurate control of quantities of materials and test conditions. It applies to laboratory specimens used for compressive and flexural strength testing and clarifies when alternate preparation methods (for example, common mold sizes covered by Methods D559 or D560) are appropriate. The document also states unit conventions, rounding/significant‑digit guidance, and safety considerations for laboratory work.

Key topics and requirements

• Specification of specimen types and dimensions for compression and flexure testing.
• Material weighing, mixing and proportioning procedures to achieve consistent soil‑cement mixes.
• Molding and compaction techniques to obtain target density and uniform specimens.
• Curing methods, temperatures, and durations to produce standardized strength‑development conditions.
• Handling and identification of specimens, conditioning prior to testing, and recommendations for storage.
• References to related test methods for compressive and flexural strength evaluation (e.g., Test Methods D1633, D1634) and guidance on unit usage and significant digits.

Typical use and users

Used by geotechnical and materials laboratories, civil engineers, pavement and foundation designers, quality control personnel, and researchers developing or verifying soil‑cement mix designs. Typical applications include laboratory mix development, acceptance testing for soil‑cement construction, and comparative research where standardized specimen preparation is required to obtain reproducible strength data.

Related standards

Commonly referenced and associated standards include ASTM Test Methods D1633 (Compressive Strength of Soil‑Cement Cylindrical Specimens), D1634 (Flexural Strength of Soil‑Cement Beams), D559 and D560 (sample preparation for specified mold sizes), and Practice D6026 (significant digits and rounding). The practice is part of the ASTM D18 committee portfolio addressing soil and rock testing.
