Curing compounds should contain a fugitive dye, or, when hot weather conditions dictate, a fugitive heat reflecting pigment.

D. The use of hardeners should be considered for special areas, but the incidental hardening of most curing compounds and sealers has been adequate. Magnesium zinc fluoresilicate hardener is generally compatible with the sodium silicate curing compounds listed above, but is not recommended for finished areas because the surface is often rough and mottled.

G. Provide temporary openings for cleanouts and inspection ports where interior area of formwork is inaccessible. Close openings with panels tightly fitted to forms and securely braced to prevent loss of concrete mortar. Locate temporary openings in forms at inconspicuous locations.

H. Clean forms and adjacent surfaces to receive concrete. Remove chips, wood, sawdust, ice, snow, dirt, and other debris just before placing concrete. The Project Representative shall inspect forms prior to placing the concrete.

I. Retighten forms and bracing before placing concrete, as required, to prevent mortar leaks and maintain proper alignment.

J. Coat contact surfaces of forms with form-release agent, according to manufacturer's written instructions, before placing reinforcement.

K. Forms shall be cleaned and treated each time they are used.

3.2 EMBEDDED ITEMS

A. Place and secure anchorage devices and other embedded items required for adjoining work that is attached to or supported by cast-in-place concrete. Use setting drawings, templates, diagrams, instructions, and directions furnished with items to be embedded.

C. When reinforcing a slab on grade use one of the following methods:

1. Place half the thickness of concrete followed by the laying of the flat reinforcement, followed by the second half thickness and vibrate it into the first.

2. Provide supports for the flat reinforcement to prevent it sinking in the pour.

3.4 WATERSTOPS

In the case of isolation joints, concrete shall be placed simultaneously against both sides of the joint.

C. Deposit concrete continuously in one layer or in horizontal layers of such thickness that no new concrete will be placed on concrete that has hardened enough to cause seams or planes of weakness.

If a section cannot be placed continuously, provide construction joints as indicated. Deposit concrete to avoid segregation.

ACI 301.

2. Do not use frozen materials or materials containing ice or snow. Do not place concrete on frozen subgrade or on subgrade containing frozen materials.

3. Do not use calcium chloride, salt, or other materials containing antifreeze agents or chemical accelerators unless otherwise specified and approved in mixture designs.

G. Hot-Weather Placement: Comply with ACI 301 and as follows:

1. Maintain concrete temperature below 90 deg.F at time of placement. Chilled mixing water or chopped ice may be used to control temperature, provided water equivalent of

033015-7 ice is calculated to total amount of mixing water. Using liquid nitrogen to cool concrete is contractor's…
