ASTM C579-23 PDF

Overview

ASTM C579-23: Standard Test Methods for Compressive Strength of Chemical-Resistant Mortars, Grouts, Monolithic Surfacings, and Polymer Concretes provides reliable procedures to determine the compressive strength of chemical-resistant construction materials. Managed by ASTM International, this standard is widely referenced for quality assurance and performance validation in environments exposed to corrosive or aggressive chemicals. It applies to materials using resin, silicate, silica, or sulfur binders and accommodates a variety of aggregate sizes with multiple test procedures designed for each.

With performance of chemical-resistant mortars, grouts, monolithic surfacings, and polymer concretes crucial in industrial and infrastructure projects, ASTM C579-23 enables precise and repeatable assessment of compressive strength-a key factor in ensuring safe, durable, and chemical-resistant construction.

Key Topics

• Compressive Strength Testing: Describes standardized procedures for determining the compressive strength of chemical-resistant mortars, grouts, monolithic surfacings, and polymer concretes.
• Scope of Materials: Includes materials with resin, silicate, silica, and sulfur binders with variable aggregate size ranges.
• Test Methods:
  • Test Method A: For systems with aggregates smaller than 0.0625 in. (1.6 mm)
  • Test Method B: For aggregates from 0.0625 in. to 0.4 in. (1.6 mm to 10 mm)
  • Test Method C: For aggregates larger than 0.4 in. (10 mm)
• Testing Rate Control: Specifies two methods of controlling the testing rate for accuracy.
• Sample Preparation and Conditioning: Details steps for preparing, curing, and handling test specimens, including guidelines for capping and surface finishing.
• Reporting Requirements: Includes documentation of material identification, mixing ratios, test methods used, specimen dimensions, observed failures, and compressive strength values.
• Precision and Reproducibility: Provides guidance on expected repeatability, reproducibility, and outlier handling based on interlaboratory studies.
