Concrete Honeycomb Repair Material

what is honeycomb in construction - basic civil engineering,the procedure of repairing honeycombs is as follows. initially the concrete particles and loosened aggregates should be removed by using a chipping hammer and a wire brush. next the area should be cleaned thoroughly with a wire brush to remove finer particles and should be washed let the surface dry well and apply “chemi-fix” glue on the area.honeycombs in concrete - their causes and remedies,at places of junction of columns and beams concrete with strictly 20mm and down aggregates should be used with slightly more water and cement to avoid honeycombs. taping with wooden hammer the sides of shuttering from outside during concreting and vibrating will help minimizing honeycombs to a great extent in case of columns and beams..
