The standard for quality control of concrete to easily slide up the form in sliding form method has not established. To rationalize this method, the speed of sliding up the form must be decided as the lost time according to the main types of occupation, that is workmen for concrete and reinforcement, waiting without working reduces to a minimum. To keep the adequate construction progress it is desirable for the speed of sliding up to be kept constantly or not more than several kinds. The compressive strength of concrete at early age is sensitively influenced by weather conditions. So past weather conditions corresponding to the construction period must be investigated and arranged. By using of this results the mixing strength of concrete must be revised by the standard value of a revised value t of the compressive strength of concrete according to temperature shown in Table JASS 5. 3. 3. The necessity of the sufficient preliminary investigation on weather conditions and material of concrete for the sake of preparing the several kinds of mixing of concrete to secure the necessary speed of sliding up is pointed and peculiar items to investigate adding to those of general concrete works is pointed, too.
