B. Repair or replace concrete not properly placed or of the specified type - <br />C. Unless the removal of a defective slab is required by the Engineer, defective surfaces, such <br />as honeycomb, shall be cut out entirely until homogeneous concrete is met, even if it <br />means going through the slab. <br />D. Such areas shall be coated with an approved epoxy bonding material, which shall be <br />applied in accordance with the manufacturer's instruction, before damp packing the area <br />with a mix consisting of one part of Portland cement and two parts of sand and fine gravel, <br />ation of materials and mixes as the situation dictates in <br />epoxy and sand mix, or any combin <br />the opinion of the Engineer. <br />E. The water content of the damp -pack material shall be such that a ball of the mix may be <br />squeezed in the hand without bringing free water to the surface. <br />F. Damp -pack material shall be tamped into place and finished to match adjacent concrete <br />surfaces. <br />G. Particular care shall be taken that no sagging of the material will occur. <br />H. The bond between any two layers of damp -pack shall be improved through the use of an <br />approved epoxy bond agent. <br />I. Surfaces which have been damp -packed shall be kept continuously damp during and for a <br />period of not less than seven days after completing the damp pack operation, by <br />polyethylene coverings thoroughly taped to the original concrete surface in a manner that <br />loss of moisture, evidence by lack of water droplets on the inside surface of the <br />polyethylene, is avoided. If this moisture condition cannot be maintained, a continuous <br />water cure may be required by the Engineer. <br />J. Under no circumstances shall Contractor apply a plaster coat over the honeycomb areas to <br />conceal the existence of the honeycomb in the concrete. <br />K. Neither Embeco nor calcium chloride shall be used for filling honeycomb areas, nor shall <br />they be mixed with damp -pack material. <br />L. Any concrete with excess air entraining agent will be rejected. <br />3.07 FIELD QUALITY CONTROL <br />A. Field inspection and testing will be performed under provisions of Section 01410. <br />B. Maintain records of placed concrete items. Record date, location of pour, quantity, air <br />temperature, and test samples taken. <br />3.08 CURING <br />A, Curing shall be by water method, continuous for 7 days unless otherwise noted. <br />B. Contractor shall use curing compounds for vertical surfaces. <br />044572017 <br />03300-5 <br />
