Is crushed concrete good for paver base?
Pavers simply sit on a strong base, such as crushed concrete, and lock into position with sand. Because pavers must support extensive weight for years, using pavers that are the proper thickness and installing them correctly are critical to prevent cracks and other decaying damage.

How long does it take for crushed concrete to harden?
How long does concrete have to harden? Concrete must regularly achieve a standard strength / minimum compressive strength until it can be built on or installed. At ideal temperature, i.e. plus degrees above 12°C or even higher, and normal ambient humidity, this is the case on average after 28 days.
