Methods of transporting concrete on site
A concrete derivative is a class that fully implements all the pure-virtual methods it inherits from its abstract base classes. Some methods may be inherited rather than implemented, however only a concrete class can actually be instantiated.
Considering the different applications and methods of concrete construction, you really can't calculate it that way.
The same way you create a concrete method in a concrete class. When a class is abstract, it can contain abstract methods. That doesn't mean that all methods must be abstract. Hope this helps.
Pre-stressed concrete is made by using,high strength steel bars(tendons).normal concrete(>M25)sheaths for cable duct.anchors.jacks.
different minerals used in concrete are cement, water, aggregates, syphorites. To find out more about concrete go to my site called www.miquel.ning.com

D concrete which r mixed in d site itself is known as in situ concrete:)
Temprature of concrete while pouring at site should be in the range 23 to 28 degree C.
Advantages of Pre-cast Concrete- Pre-cast concrete slabs are usually the correct size as it is manufactured off site.- Pre-cast concrete saves a lot of time on site as it is manufactured off site.- Pre-cast concrete also saves a lot of space on site as pre-cast concrete is usually on site when required.- Pre-cast concrete saves money in terms of labour on site as pre-cast concrete can usually be assembled by semi skilled operatives.Disadvantages of Pre-cast Concrete- Pre-cast concrete lacks design and dimension flexibility as the manufactures may only have fixed shapes and sizes.- Pre-cast concrete may affect the construction programme as the delivery on site may not always be on time.- Pre-cast concrete may incur addition financial costs as delivery on site may not always be on time.- Pre-cast concrete allows for a very small margin for error as the incorrect dimensions of pre-cast concrete may result in changing the entire design.
food, water for drinking and mixing concrete, and oil and gas for the transporting trucks.
There are three important construction methods for a swimming pool: concrete, vinyl liner and fiberglass. The most used construnction method for a swimming pool is concrete.
