This current flow can arc across any gaps in its path. If that arc takes place within a flammable material, it can cause a fire or explosion. If the arc takes place within a bearing, such as in a pump in a treatment plant, it can scar the bearing and cause premature wear. If it takes place on a circuit board, it can damage the circuit board.

Beam Bearing on Concrete. Last Revised: 06/16/2011. A bearing plate takes the reaction of a steel beam and distributes that force over a larger area that is made of a material that is not as strong as steel. The action is essentially the same as a footing that distributes a large load to softer soil.
For rolling element bearings, the situation is even worse. Not only will water destroy the oil film strength, but both free and emulsified water under the extreme temperatures and pressures generated in the load zone of a rolling element bearing can result in instantaneous flash .
Concrete containing lightweight aggregates and carbonate aggregates retain most of their compressive strength up to about 1200 oF. Lightweight concrete has insulating properties, and transmits heat at a slower rate than normal weight concrete with the same thickness, and therefore generally provides increased fire resistance.
In this paper, the concrete underneath the base plate together with the base plate is referred to as "component concrete in compression and base plate in bending" or in short "concrete in compression". Models are presented for the determination of the resistance and stiffness of this component. The models have been validated with tests.

I want to use a mace sledgehammer to destroy that wall. ... Brick Walls are usually load bearing or nonload bearing. Generally you can identify them by their width.
Cinder blocks, made from pouring concrete into a cast, are used as walls in buildings or as support units for other structures. While these blocks can handle both weight and weathering, the cinder block does have weaknesses. In fact, elements from the outside, and occasionally from within, can damage, crumble and destroy cinder blocks.
Concrete can deteriorate for a variety of reasons, and concrete damage is often the result of a combination of factors.

What you need to pay attention in footing design are the soil bearing capacity and punching shear on the footing. If the soil bearing capacity on the site you build your footing is more than 20/3 ton per feet square (or exactly ton per feet ...
If you are doing a smaller home project with no special accelerants added to your mix, your loadbearing strength per concrete yard will be 3,000 psi. This is the standard psi of a common mix. If accelerants are called for, you must consult a licensed structural engineer for the loadbearing calculation.

Neat cement and bentonite are the two main materials used for making grout slurries. Portland Cement, ASTM Type I or API Class A B Portland cement is a mixture of lime, alumina, magnesia, and sulfur xide. The components are combined and heated, and the resulting "clinker'' is ground up and mixed with gypsum to make various types of cement.
