REFERENCE TEST METHODS AND A PERFORMANCE CRITERION FOR CONCRETE STRUCTURES

The reliability of the ASTM C 227 and CSA A 23.2.14-A test methods has been improved by the use of containers and reactors at 38 degrees C. Increasing the cement content from 310 to 410 kg/cubic m reduces the response time of the concrete test from 12 to 8 months. The performance test carried out at 60 degrees C can be used to check the effectiveness of preventive measures (low alkali cement or mineral additives) when used with reactive aggregates from a given construction site. The response time of this test is then 4 to 8 weeks. (A) For the covering abstract see IRRD 871351.
