Actually cinder blocks and concrete blocks were and still are made from two
different materials. Cinder blocks used "clinkers" from coal fired
locomotives and industrial steam boilers, mixed with portland cement and
sand to form a lightweight version of concrete. Lightweight blocks are still
manufacturered for internal firewalls and such, using steel mill slag and
other lightweight agegates. They were never intended for outdoor use or
inground use. Concrete blocks used the standard sand, gravel and portland
cement for high strength and weather resistance.

Used to be called Rawlplug in North America when they were made of a
fiberous material. My experience has shown that plastic plugs don't hold
much at all, they are just too slippery to form a solid anchor. If you have
solid timbers in the wall use longer screws. If you have masonry building
units in the wall get some Tapcon screws or the equivelent in a length that
will solidly hold in the masonry.

Pollyfilla, still made in North America, they make floor leveling, wall
patching, spackles and other plaster type supplies. My local big box store
stocks them.
