ASTM C190 – Summary Table | |
---|---|
Standard Number | ASTM C190 |
Title | Standard Test Method for Tensile Strength of Hydraulic Cement Mortars |
Purpose | To determine the tensile strength of hydraulic cement mortar using briquette specimens. |
Test Specimen | Briquette-shaped mortar specimens (standard dumbbell shape) |
Dimensions | Typical cross-sectional area at neck = 645 mm² (1 in²) |
Apparatus | Tensile testing machine with grips for briquettes |
Procedure |
Prepare mortar briquettes, cure under standard conditions, test by applying tension until failure at a controlled rate. |
Calculation | Tensile Strength = Maximum Load ÷ Cross-sectional Area |
Significance | Provides insight into the tensile performance of cement mortar, important for cracking resistance. |
Units | Reported in psi or MPa |
Applications | Research, quality control of cementitious materials, and mix design evaluation. |
