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 /> epoxy and sand mix, or any combination of materials and mixes as the situation dictates in <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 /> IA. Field inspection and testing will be performed under provisions of Section 01410 , <br /> I 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 /> LB . Contractor shall use curing compounds for vertical surfaces . <br /> 044572017 <br /> 03300-5 <br />
