Standards, test methods, specifications and acceptance criteria
NCMA Standards
NCMA (National Concrete Masonry Association) is a prominent organization in the United States dedicated to the advancement of concrete masonry industry.
NCMA standards provide a framework for:
- Product quality: they establish minimum requirements for the production of concrete masonry units (CMUs), including their size, shape, strength, and durability.
- Material specifications: they outline specific guidelines for the raw materials used in CMU production, such as aggregates, cement, and water.
- Testing procedures: they detail standardized testing methods to assess the physical and mechanical properties of CMUs, including compressive strength, water absorption, and freeze-thaw resistance.
- Installation practices: they offer recommendations for proper installation techniques to ensure the structural integrity and longevity of concrete masonry walls.
By adhering to NCMA standards, the construction industry can:
- Reduce risk: minimize the risk of construction failures and costly repairs by using high-quality, code-compliant CMUs.
- Improve efficiency: streamline the construction process through standardized product specifications and installation practices.
- Enhance building performance: achieve optimal building performance in terms of energy efficiency, durability, and fire resistance.
- Facilitate innovation: encourage the development of innovative concrete masonry products and construction techniques.
NCMA standards:
- NCMA CMU-WR1 – Water Stream and Water Droplet Tests of Concrete Masonry Units
- NCMA CMU-WR2 – Spray Bar Test of Concrete Masonry Units
- NCMA CMU-WR3 – Assessing Water Uptake Potential of Concrete Masonry Units
