I can't find it anywhere now but I know I've read that cinder blocks will burn in a fire.
I think they've already burned in a fire.

[Jerry, I am 81 years old and have never seen black concrete blocks or cinder blocks. I am from Ohio. Always the light grey cement ones. Maybe you are from Appalachia where they have more coal than cement. The black ones in the picture are obviously cement blocks painted black.

The black blocks shown in the pictures have either been painted black or have had black colouring added. Their colour is too dark and even. The cinder blocks I remember (going back about 65 years) were a grayish colour with almost a tint of blue to them. With flecks of something very dark sprinkled through them. My recollection is that the dark flecks might have been coal or coke clinker (or even cinders ?).

Cinders are clinkers that have been broken up or crushed

I just looked up cinder/clinker and got reminded that the blocks were called breeze blocks. I remember that is what my father called them. Apparently an English term but also used here in NZ. It appears to be exactly the same as the US clinker/cinder blocks.
It looks like cinder/clinker could be used to describe either some sort of byproduct from the production of coke (and I remember there used to be a big coke production facility near the old gasworks here so I am guessing that would be the source. The old gasworks now has a car sales yard on top) or what was left in the firebox from steam engines, of which there also used to be plenty of.

From age 14 - age 21 I tended a coal fired furnace in our first house every evening after school I would remove the clinkers from the retort in the fire box and then shoveled out the smaller pieces and ash they were place in a pile to cool and then spread on our parking area in the back yard. the area when from just barely usable for parking to fantastic in those seven years and didn't cost anything for material.

The Romans buildings are still standing because the concrete they used is 'self healing'. https://www.scientificamerican.com/article/ancient-roman-concrete-has-self-healing-capabilities/
