摘要

The report discusses procedures for preparation of horizontal construction joints using a high-pressure water jet,to compare these procedures with the alternative practice of wet sand-blasting,and to develop additional information on procedures and methods that have been used in horizontal construction joint practice. The investigation is divided into two phases,laboratory and field. One 6-in. maximum size crushed limestone aggregate concrete mixture,with a cement content of 235lb/cu yd,an air content of 6plus or minus percent,and a slump of 2plus or minus 1/2in. on the portion of the mixture passing the 1-1/2-in. sieve,was used to cast specimens for both phases.
