Yes,
Cinder concrete cab be used for sunken portions of the slabs over water proofing.

Some contractors recommend and use cinder in the sunken parts of a reinforced cement concrete slab. Others caution against it in construction where a lot of seepage can occur because cinder can have a tendency to retain the water.
Concrete block is made from Portland Cement, water, sand and aggregate. The aggregate may be in the form of flyash or cinder from burnt coal.
Cinder blocks differ from concrete blocks in other ways besides their hollow design. Concrete blocks are made from slurry of Portland cement and small aggregate, such as small stones or gravel. Cinder blocks, on the other hand, are made from a combination of Portland cement and cinders, the dusty remnants of burned coal. The result is a lighter weight block formed into a rectangular masonry block. Although many people use the terms "cinder blocks" and "concrete blocks" interchangeably, a true cinder block will always be lighter than a concrete block, and the texture of cinder blocks may be rougher than finished concrete blocks. When bricklayers work with cinder blocks, they generally use techniques similar to standard brick lying. The alternative rows of cinder blocks are carefully offset so that the second layer stabilizes the first. A line of mortar is put down between cinder blocks, so the actual dimensions of a standard cinder block may be adjusted slightly to accommodate the mortar. Corners may be finished out with half blocks, or interlaced to create a four-cornered structure.
It weighs 59 lbs. There is a difference between a "real" cinder block and a concrete block. A cinder block uses cinders--ash from the burning of coal--as its aggregate. Concrete blocks are made from concrete. Concrete block is far stronger than is cinder block, and some jurisdictions prohibit the use of cinder block. The only justification for cinder block is that it weighs less than concrete block, which is important if the ground you're building on isn't strong enough to support a heavy structure. This justification has gone away, because now you can buy concrete block made from expanded-shale aggregate that's as light as cinder block and as strong as standard-weight concrete masonry.

If the cinder blocks are somewhere inside, maybe. Personally, I'd prefer to use a concrete primer.
