Cast in place cylinder strength relates to the strength of concrete in the structure due to the similarity of curing conditions because the cylinder is cured within the slab However due to differences in moisture condition degree of consolidation specimen size and length diameter ratio there is not a unique relationship between the strength of cast in place
This test method covers determination of the compressive strength of hydraulic cement mortars using 2 in or [50 mm] cube specimens Note 1 Test Method C349 provides an alternative procedure for this determination not to be used for acceptance tests This test method covers the application of the test using either inch pound or SI
According to ASTM C39/C39M the compressive strength of a concrete specimen cylinder is calculated by dividing the maximum load applied during the test by the area Compressive strength tests are crucial for determining the load rate sensitivity of concrete emphasizing the importance of accurate and repeatable control rates
This test method covers determination of compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores It is limited to concrete having a density in excess of 800 kg/m 3 [50 lb/ft 3] The values stated in either SI units or inch pound units are to be regarded separately as standard
1 This test method is under the jurisdiction of ASTM Committee C09 on quality control of concrete proportioning mixing and placing Concrete and Concrete Aggregates and is the direct responsibility of Subcommittee on Testing Concrete for Strength Current edition approved July 10 2003 Published October 2003 Originally approved in 1921
Significance and Use This test method provides a means of determining the compressive strength of hydraulic cement and other mortars and results may be used to determine compliance with specifications Further this test method is referenced by numero ASTM grants Licensee a limited revocable nonexclusive non transferable license to
Significance and Use This test method affords a means for determining the compressive strength of grouts that expand and in use harden under conditions of partial to total restraint It is particularly applicable for determining the effect on c
any material tested for compressive strength results in lower measured strengths To address this ASTM C140 now adjusts the compressive strength of all concrete pavers with an aspect ratio thickness divided by width factor to that of a 23/8 60 mm by 3 7/8 98 mm thick concrete paver This thickness was selected because the 8 000 psi 55
Care must be exercised in the interpretation of the significance of compressive strength determinations by this test method since strength is not a fundamental or intrinsic property of concrete made from given materials Values obtained will depend on the size and shape of the specimen batching mixing procedures the methods of sampling molding
Values obtained will depend on the size and shape of the specimen batching mixing procedures the methods of sampling molding and fabrication and the age temperature and moisture conditions during curing This test method is used to determine compressive strength of cylindrical specimens prepared and cured in accordance with Practices
