What is the time required to demoulding concrete column, slabs after casting?

 Normally low to medium rise buildings are desigined for gravity loads, then checked for their ability to resist lateral loads. However high rise buildings are mush more susceptible to lateral forces action, therefore the amount of materials needed for resistance of lateral forces increases at a drastically accelerating rate. Therefore in the high rise buildings still use the reinforced concrete with huge amount of steel rebars, instead of using the composite
