Production Line For Half Cored Concrete Block

Two-hour fire ratings| Concrete Construction Magazine

For cored units, the equivalent wall thickness is calculated by multiplying the percent solid by the wall thickness. Thus, an 8-inch unit that is 55% solid would have the equivalent thickness of just over 4 inches. NCMA Tek 7-4 discusses the use of core fillers to increase the fire resistance of concrete masonry.

Concrete Block Types & Sizes

Construction Updates

4/10/2013 · Extreme weather may cause degradation of the surface due to frost damage. This type of damage is common with certain types of brick, though relatively rare with concrete block. If non-concrete (clay-based) brick is to be used, care should be taken to select bricks suitable for the climate in question.

Do brick walls effectively protect against ionizing

While I could not find data for "brick," they do have it for concrete here, reproduced below. We are interested in the solid line, which shows energy lost by the radiation. The dashed line shows energy taken in by the material, which can be slightly less if some energy is lost, say, to escaping neutrinos.

Infill walling

Infill walling is the generic name given to a panel that is built in between the floors of the primary structural frame of a building and provides support for the cladding system. Infill walls are considered to be non-load bearing, but they resist wind loads applied to the façade and also support their own weight and that of the cladding.
