Control Joint Slot

All the units drawn in the Shapes and Sizes Directory are drawn without any control joint slots. Superlite manufactures a certain ratio of regular block to control joint block within a pallet of material. The general rules for the amount of control joint block manufactured with regular units are follows: 6" wide block 1 control joint block for every 4 regular block 8" wide block 1 control joint block for every 3 regular block 10" wide block 1 control joint block for every 2 regular block 12" wide block 1 control joint block for every 2 regular block All half block are manufactured with a control joint slot. The only exception to this is when we manufacture a splitface on side one end, and a splitface two sides one end. Superlite Block manufactures its units in this manner unless specified otherwise. Compressive Strength of Masonry Structural performance of masonry is based on the physical characteristics of its components, and on the construction methods used in assembling these components. The strength of masonry is influenced by the structural properties of units, grout, mortar and reinforcement. In engineered masonry structures, the required strength of structural elements is determined by distributing design loads to the various resisting elements in accordance with a structural analysis. After the required strength is determined, the designer uses it as a basis for specifying f'm, which is defined as the "specified compressive strength of masonry". This property is noted in the project documents and is used I accordance with masonry design codes to establish allowable stresses for masonry elements.
