Using charcoal

Does anyone have information on using charcoal as a soil conditioner?The charcoal has come from bonfires ,used to clear mostly hazel and hawthorn shrubs .I have extremely heavy neutral ph soil and am mostly growing vegetables on it.

Welcome to tools and techniques

Can anyone help with the following queries please ?

Can you use Builders sharp sand for mixing with potting compost in order to make it better draining?A local DIY store sells horticultural sharp sand (double the price of the builders sand) and it mentions that it is `lime free`.Should I do a ph test on the Builders sand to check that it is ok?
