Biological shield radiation exposure. As noted, concrete is used in a wide range of structures for typical LWRs. A summary of concrete structures in LWR plants can be found in Hookham (1995). In relation to total radiation exposure, the biological shield walls are of utmost interest as these safety-related structures encase the reactor and ...

The cost of grinding to a higher fineness is considerable, and also the finer the cement the more rapidly it deteriorates on exposure to the atmosphere Finer cement leads to a stronger reaction with alkali-reactive aggregate, and makes the cement paste, though not necessarily concrete, exhibit a higher shrinkage and a greater proneness to cracking.

Portland cement is a light grey powder that poses little immediate hazard. A single short-term exposure to the dry powder is not likely to cause serious harm. However, exposure of sufficient duration to wet Portland cement can cause serious, potentially irreversible tissue (skin or eye) destruction in the form of chemical (caustic) burns.

High-pressure grinding rollers (HPGR) During the high-pressure comminution process, rather than being crushed between the roller surfaces, individual grains or particles are in effect compacted to a dense flake through exposure to relatively high pressures. Following de-agglomeration, the flake normally shows a substantial amount of completed or incipient …

10%In conclusion, children living and attending school in an urban area exposed to cement plant emissions show a chronic bioaccumulation of toxic metals, and a significant exposure to PM 10 pollution. Cement plants located in populous urban areas seem therefore harmful, and primary prevention policies to protect children health are needed.
