The paper describes the use of in-place testing instead of standard cylinder testing. Removal of forms and shores, and determination of concrete strength compliance with specifications were all controlled by pullout tests.
The criteria were written into the contract specification, and the relevant sections are quoted as a model for future use. Based on correlation data with standard cylinder tests, the building officials allowed the elimination of the usual mandatory standard cylinder tests. Standard tests were made however to provide comparison with the in-place tests. The paper shows that the in-place test provided an adequate measure of the quality and strength of the concrete.
