B . Mortar for Glass Unit Masonry Assemblies : Comply with ASTM C 270, Proportion Specification for <br /> Type S mortar. I J <br /> 1 . Combine and thoroughly mix cementitious materials, water, and aggregates in a mechanical batch <br /> mixer, unless otherwise indicated. Mix mortar to produce a stiff but workable consistency that is <br /> drier than mortar for brick or concrete masonry. Discard mortar when it has reached initial set. <br /> PART 3 - EXECUTION <br /> 3 . 1 EXAMINATION <br /> A. Examine sills, jambs, and heads surrounding glass unit masonry assemblies for compliance with <br /> requirements for installation tolerances and other conditions affecting performance. <br /> 1 . Proceed with installation only after unsatisfactory conditions have been corrected. <br /> 3 . 2 INSTALLING GLASS BLOCK WITH MORTAR <br /> A. Set glass block with completely filled bed and head joints, with no furrowing, accurately spaced and <br /> coordinated with other construction. Maintain 3/8-inch ( 10-mm) exposed joint widths, unless otherwise <br /> indicated. <br /> B . Install panel reinforcement in horizontal joints at spacing indicated and continuously from end to end of <br /> panels ; comply with the following requirements : <br /> 1 . Vertical Spacing of Panel Reinforcement for Exterior Panels : Every other course but not more <br /> than 16 inches (407 mm) o . c . , starting with first course above sill. <br /> 2 . Vertical Spacing of Panel Reinforcement for Interior Panels : Not more than 16 inches (407 mm) <br /> 3 . Do not bridge expansion joints with panel reinforcement. <br /> 4 . Place panel reinforcement in joints immediately above and below all openings within glass unit <br /> masonry assemblies . <br /> 5 . Lap panel reinforcement not less than 6 inches ( 150 mm) if more than 1 length is necessary. <br /> 6. Embed panel reinforcement in mortar bed by placing lower half of mortar bed fust, pressing panel <br /> reinforcement into place and covering with upper half of mortar bed. <br /> C . Install panel anchors at locations indicated and in same horizontal joints where panel reinforcement <br /> occurs. Extend panel anchors at least 12 inches (300 mm) into joints, and bend within expansion joints at <br /> edges of panels and across the head. Attach panel anchors as follows : <br /> 1 . For new unit masonry assemblies, embed other ends of panel anchors, after bending portions <br /> crossing expansion joint, in horizontal mortar joints closest in elevation to joints in glass unit <br /> masonry assemblies containing panel anchors . <br /> D . Use rubber mallet to tap units into position. Do not use steel tools, and do not allow units to come into <br /> contact with metal accessories and frames. <br /> E. Use plastic spacers in mortar joints to produce uniform Joint widths and to prevent mortar from being <br /> squeezed out of joints . <br /> 1 . If temporary wedges are used, remove them after mortar has set and fill voids with mortar. <br /> Wabasso Beach Park <br /> Indian River County <br /> DAA Project No . 6008 <br /> 04815 -4 <br />
