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 | 27.81 | 5.95 | 10474.7 | 291301 | 2 |
2 | 28.27 | 6.00 | 10216.8 | 288828 | 3 |
DIME Test ID: 2015-01-16-2-1
Number of specimens: 2
Compressive strength (to nearest 10 psi): 10350
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 of the same cylinder differ more than 2%. Please check cylinder molds prior to sampling concrete cylinders.
Age of specimen: 28 days
Certified By: She Vang
