before plcement in any mold with out compction is the fresh concrete. or just after plceing the concrete before initial setting is the fresh concrete.
You should wait a minimum of 28 days before you seal concrete. If you pour your concrete in summer, than a minimum of 14 days is acceptable. If you seal concrete any quicker, there is a chance moisture will be trapped inside.
Imediatly after trowling
it has to be tacky!!!!!!!
That depends on the concrete, as well as weather conditions, and the load the concrete would be subjected to. Concrete gains strength over time and the usual benchmarks are 7 days, and 28 days. At 28 days concrete has usually cured to nearly its maximum strength. For a concrete footing in a residential environment say a deck or home the concrete will usually cure for a minimum of three days before the formwork is removed and the rest of the structure is built. For a commercial or civil project the curing is subject to the engineers discretion.
The gaps that are put in place at the time of construction are called, "expansion joints". When concrete, and other materials, heat up, they expand. If concrete expands too much it will press against other sections of concrete and can break or "buckle". When sections of concrete press against each other too hard, sometimes two adjacent sections will press up, creating a dangerous condition for anyone walking on the sidewalk. Expansion joints give a little space for the concrete to expand before anything bad happens. Even with expansion joints, it's sometimes not enough.
There are several ways that the thermal expansion joints in a concrete road surface can be made:cut by a concrete saw after the concrete sets, there is no material in the jointfilled with a compressible fiberboard spacer before pouring the concrete, this spacer is left behind in the joint and easily compresses when the concrete expands and expands when the concrete contractsfilled with interleaved steel teeth before pouring the concrete, these teeth slide past each other as the concrete expands and contracts they provide a smoother road surface and are commonly used on bridgesetc.
Before the sidewalk
To replace the decorative tile border on a concrete pool, the pool will have to be drained. The old tile needs to be taken off and a new tile with waterproof grout or concrete can be installed. The pool should dry for a week or so, before it is refilled.
Nope you will need the burning crusade expansion installed before it will allow you to install WotLK.
you cant. u have 2 have the sims 2 installed before u have any expansion packs

To prevent sidewalks from cracking in random spots and breaking apart, builders make lines in sidewalks. The technical term for sidewalk lines is contraction joints. Contraction joints are placed in fresh concrete before the concrete dries and has a chance to create its own joints, which we call cracks.
Playing Cataclysm requires you to already have installed World of Warcraft, as well as the Burning Crusade and Wrath of the Lich King expansion packs.
You may have installed the expansion pack, but do you know if it is activated? Look for the game data in the startup dialog and make sure that Shivering Isles is activated. Alternatively, you could visit the Nexus forums and search for the Nexus Mod Manager. This application detects installed packs and mods and you can activate or deactivate them there. You may also have to wait a little longer or actually swim out to the island before the expansion notices the quest.
Windows should be installed after sheathing and before siding.
