Lead-lined ma

41、sonry units have a broad range of lead thicknesses. Lead-lined masonry units offer the advantages that they are relatively simple to construct, provide considerable structural strength, and may be surfaced easily with plaster. However, the cost is considerably higher (up to a specific kV) than using

Each unit shall have a single thickness of unpierced lead sheet bonded or anchored permanently in the center of the unit/block. Construct blocks to provide an effectiv
