AUXILIARY DEVICE FOR CAPPING CONCRETE COMPRESSION, CAPABLE OF INCREASING ADHESIVE FORCE BETWEEN CONCRETE COMPRESSION AND CAPPING MATERIALS

摘要

PURPOSE: An auxiliary device for capping concrete compression is provided to reduce laitance generated on the top of concrete compression.;CONSTITUTION: An auxiliary device for capping concrete compression comprises a mold(20) for capping, an uneven protrusion, and a small hole. The mold for capping is inserted into the top of the auxiliary device for capping. The uneven protrusion has various shapes such as a circular dome, a cone, a cylinder, a square pillar, a trigonal column, and a polygon column. The small hole is formed between the uneven protrusions of the auxiliary device for capping. The small hole discharges the moisture or the air remaining between the auxiliary device for capping and the mold for capping.;COPYRIGHT KIPO 2011
