ASTM C190
Full Name
ASTM C190 – Standard Test Method for Tensile Strength of Hydraulic Cement Mortars
Scope
ASTM C190 is a standard test method that outlines the procedure for determining the tensile strength of hydraulic cement mortars. Tensile strength is the maximum stress a material can withstand before it breaks under a tensile load. This property is important for evaluating the strength and durability of mortars used in construction applications, such as masonry walls, plastering, and flooring.
Key procedures specified in ASTM C190 include:
- Mortar preparation: a standard mortar mixture is prepared using specified proportions of cement, sand, and water. The ingredients are mixed to a consistent consistency, ensuring uniform distribution of the components.
- Molding: the prepared mortar is molded into cylindrical or prismatic test specimens of a specified size. The specimens are carefully compacted to eliminate air voids and ensure consistent density.
- Curing: the molded specimens are cured under controlled conditions to simulate field conditions. This involves storing the specimens in a moist environment at a specified temperature for a specified period.
- Testing: the tensile strength of the specimens is determined using a tensile testing machine. The specimens are loaded gradually until they fail. The maximum load applied before failure is recorded and used to calculate the tensile strength.
