Allow Proper Time to Water Cure

After concrete is placed, the concrete increases in strength very quickly for a period of 3-7 days. Concrete which is moist cured for 7 days is about 50% stronger than uncured concrete. Read about properly curing concrete slabs. Water curing can be done after the slab pour by building dams with soil around the house and flooding the slab.
