· That cement would add about ( x ) to the cost of a 50pound bag of concrete. Cement is such a valuable material, it's arguable .
Self Curing Concrete
So, the advanced technology of concrete curing, named SELF CURING CONCRETE concept was introduced with the help of different research in the US by Paul Klinger in 1957 in which the internal curing inside is possible within concrete.. In the practice of selfcuring concrete, the small inclusions are dispersed to entire concrete mass which holds the extra molecules of water necessary for ...
Concrete Technology
In concrete technology and industry, it is known that the ingredients for a bad concrete are exactly the same as for a good concrete. It is the relative proportions that matter. Furthermore, since Feret, Bolomey or Abrams, it has been established that the compressive strength depends mainly on the watertocement ratio (w/c) and not so much on the specific amount of cement used in 1 m 3 .

CEMENT CONCRETE . The cement concrete is a mixture of cement, sand, pebbles or crushed rock and water, which when placed in the skeleton of forms and allowed to cure, becomes hard like a stone. Properties of Cement Concrete: It has high compressive strength. It is free from corrosion and there is no appreciable effect of atmospheric agents on it.
8 Reasons why AirCrete needs to replace Concrete in ...
This is why we think you should replace concrete with aircrete in construction today. 1. Economical. The low cost associated with construction is the foremost reason to incorporate aircrete instead of concrete. It eliminates aggregate materials like gravel, stones or rocks mixed with cement through a laborious process by the construction ...
