The invention discloses an ocean
engineering repair
mortar and a preparation method thereof. The repair
mortar is prepared from, by weight, 20-30 parts of
alite-sulphoaluminate
cement, 15-25 parts ofmaritime work
Portland cement, 1.5-3 parts of an ultra-disperse shrinkage-reducing
water reducer, 0-5 parts of a thickening
time control agent, 1-5 parts of a reinforcing
powder, 1-4 parts of an anticorrosion compacting agent, 6-8 parts of a crack-proof and waterproof expanding agent, 5-30 parts of ultrafine mineral
powder, 0.1-0.6 part of an antifoaming agent, 0.5-2 parts of redispersible latex
powder and 50-80 parts of
quartz sands. The ocean
engineering repair
mortar has the advantages of short
setting time, fast strength development, high
bonding strength with concrete, good stability andno
cracking, and can improve the
seawater erosion resistance of repaired concrete, prevent secondary damage, prolong the service life of buildings and save a large amount of reconstruction funds.
