Slabs made very fast

[bandramir.raja]

This might be in the wrong section, please correct me

Normally a reinforced concrete floor (slab) needs curing of at least 28 days (normally less) before any load is put on it, so how are tall skyscrapers like empire state building, taipie 101, and recently burj khalifa made so quickly. I saw on a documentary that a floor is created every 3 days!

Dear bandramir.raja

They used admixtures to make Rapid Hardening and Fast setting concrete. Also to cope with extreme Dubai temperatures they used ice shavings in the concrete.

Normally Concreate sets in 7 to 8 hours...So you can use slabs after one week for some small construction works

The objective of the game+wow gold
wow gold Thinking about the nice Essence of Wintergrasp XP buff and the Stone Keeper's shards when your faction controls this PvP zone, you may be wondering what's now going on in this zone? Portals to Wintergrasp will appear in the Silver Enclave (A) and the Sunreaver's Sanctuary (H) when the battle begins. If the portal is not available, players can also fly into the zone or wait until portals reappear as each faction's Battle-Mages open portals and call out for reinforcements. You'll also see calls in the Trade channel to group up. Being part of a raid group is integral to success in this new battleground. You will flag for PvP and be attackable by the opposing faction once you enter the Wintergrasp zone.

Objective The objective of the game is control of a Titan Relic, which lodges in Wintergrasp Keep, within the Wintergrasp Fortress. Each game has a set time limit, though reports of its length vary. Defenders must protect Wintergrasp Fortress to prevent the enemy from entering the Keep to right-click and channel the Titan Relic to transfer its attunement to their faction. In order to enter the Keep, the attacking forces must destroy the walls and towers of the Fortress and then destroy the door of the Keep. This is accomplished through the use of siege vehicles.

Factories Siege vehicles are manufactured in factories. There are a total of six factories in Wintergrasp. Two are within the Fortress. They cannot be captured, but they can be destroyed. Two factories are in the ring zones right outside the fortress. These can be captured or destroyed. The two other factories, found to the southeast and southwest are like the factories within the fortress and cannot be captured, only destroyed. Cutting off the opposing faction's supply of siege vehicles can be a game changing strategy. A factory is captured just like taking a tower in Eye of the Storm, by destroying all members of the opposing faction and occupying the workshop. Siege vehicles are a new addition to World of Warcraft PvP. They are an absolute necessity for the offense and a vital part of the defense's arsenal. When ready they can be brought into the field. Each factory entitles a faction to four vehicles. Since each faction has two factories, which cannot be destroyed, each side will always have a minimum of eight vehicle slots. This can shift up to six**** available slots if both the East and West factories are controlled as well.

Siege Vehicles There are three types of siege engines which can be deployed. The Wintergrasp Catapult is a fast vehicle, but low on hit points (30k). Its abilities are Plague Barrels, which deal 500 siege damage to a structure and lay down a mist of disease that damages players who stand in it. This vehicle also has a channeled Flame Breath, which damages opposing players to the approximate tune of 1k per tick. One must have a rank of Corporal to build and use this siege engine.

The next two vehicles require a rank of First Lieutenant to build. The Wintergrasp Demolisher can carry up to 2 players. One player is the driver. The other slot is for ranged DPS. The passenger can cast and attack as though he or she is standing still. The vehicle itself has two attacks. There is a boulder that can be thrown from a distance. It does about 1k damage to structures. There is also a battering ram effect, which deals about 1500 damage. These are sturdier than the catapults, with around 50k hit points, but they move more slowly. fdhrtyrtuytuihjg

The Wintergrasp Siege Engines also requires a rank of First Lieutenant to build. This is the largest vehicle players can build. It deals 2,000 siege damage and can also knock back players and other vehicles. It can carry two passengers, but they cannot cast while in the vehicle. It is a good place for a player who is low on health to take a breather to recover health and mana. They are the slowest of all the vehicles.
