Concrete's ability to set is determined by the amibent air temp.
High early strength concrete can be used to get strength earlier, but that has its own disadvantages.

But fundamentally, concrete hydration is a chemical process that proceeds at its own pace. It takes several weeks before concrete approaches its ultimate strength.
