PRACTICAL STUDY ON PREPARATION OF EXECUTION CIRCUMSTANCE FOR CONCRETE SLAB BASED ON REQUIREMENT QUALITY

Abstract

Buildings should be constructed under suitable execution circumstances according to users’ requirement quality. From this concept, actual construction experiment of concrete slab was carried out. When quality grades of flatness were shown, the finishing worker replied execution circumstances to achieve them. Most of differences were ways of screeding. After approving by the construct superviser, slabs were constructed under these circumstances. Then they almost became slabs of demanded quality. But when the high quality was required, the grade was not achieved partly.
