REPAIRING AND REINFORCING METHOD OF CONCRETE STRUCTURE IN PRE-WETTING SPRAYING MANNER USING MIXER SHAFT OF DOUBLE AUGUR

摘要

The present invention relates to a repairing and a reinforcing method of concrete structures using a mixer shaft of a double auger in a pre-wetting spray manner, which supplies (1) a main material part and (2) a composition to a pre-wetting spraying apparatus having a mixer shaft to enable (1) the main material part and (2) the composition to be mixed and transferred at the same time wherein (1) the main material part comprises 10 parts by weight of Portland cement; 1-8 parts by weight of alumina cement; 10-20 parts by weight of a high strengthened fine powder mixing material; 5-10 parts by weight of red mud; and 1-10 parts by weight of ore, and a composition consists of (2) 5-20 parts by weight of a swelling agent, for 100 parts by weight of the main material par, (3) 5-10 parts by weight of a superplasticizer, (4) 1-5 parts by weight of an antifoaming agent and (5) 1-10 parts by weight of cellulose derivatives, thereby having outstanding strength and durability and being accordingly used in roads in which corrosion and erosion are frequently caused and having less contraction and a good watertight property and being accordingly used in cut-off structures like water-proof roof slab, a swimming pool and a purification plant.;COPYRIGHT KIPO 2015
