The following testing has been tested in accordance with:
ASTM C39-10 : Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens
Capped in accordance with ASTM C617/CTM521
Specimen | Cross sectional area of cylinder (in^2) | Average diameter of cylinder (in) | Compressive strength of cylinder (psi) | Maximum load on cylinder (lb) | Type of fracture pattern of cylinder |
---|---|---|---|---|---|
1 | 28.46 | 6.02 | 3402.0 | 96822 | 6 |
2 | 28.37 | 6.01 | 4082.1 | 115809 | 1 |
DIME Test ID: 2014-11-17-3-1
Number of specimens: 2
Compressive strength (to nearest 10 psi): 3740
Comment on any defect in either specimen or caps (Max 250 Characters): Both cylinder diameters for each specimen are not in compliance. w/ ASTM C39 section 6.1. Diameters measured differ more than 2%.
Age of specimen: 14 days
Certified By: She Vang
Test ID: 2014-11-17-3-1: Cylinders average diameters are not within 2% requirement Please check cylinder molds.
*Subject to final inspection by the Resident Engineer. |
