We cut the concrete flooring in our plant for some plumbing work and will soon re-pour a slab of 5,000 PSI "High-early" concrete. In order to minimize down-time we need to re-install equipment by drilling/anchoring into new concrete as soon as the curing has yielded sufficient strength. The equipment would be anchored using 1/2"X3" stainless steel wedge anchors and weighs cca 500#'s. It rests on 4 3"x3" feet forming a cca 5' square. Will two days of curing allow for sufficient strength to drill and compress wedge anchors without causing the new concrete to break under the tension?
