PSA Connection Grout is an ultra high strength, shrinkage compensated Class C grout, for application at a flowable, fluid or trowellable consistency. PSA Connection Grout is designed for use where very high ultimate compressive strength (in excess of 100MPa) is required. Add the required water (3.6 to 3.8 litres for fluid consistency) to the mixing vessel and slowly introduce powder with mixing for 3-5 minutes. Ensure a constant head of grout is maintained when flowing through formwork to minimise the formation of air pockets under the base plate. Please refer to the SDS for this product for further instructions and precautions.
PSA Connection Grout is to be used as a system with the PSA S-Connection. PSA’s S-Connection is a patented grouted panel-to-panel connection that has been designed to replace heavy cast-in-plates (approx. 200kN capacity) and, in some applications, to replace full height panel connections (i.e. full height ‘wet-joint’ connections) by simply stacking the S-Connection throughout the height to increase capacity.
The S-Connection consists of two plastic inserts that are cast into two adjacent precast panels, with an engineered ribbed profile to ensure strong engagement to concrete. The “A” Male insert houses and assembly of two N24 horizontal dowels which makes up the “Bridge.” Once the precast elements are installed, the “Bridge” frame simply slides across into the receiving “B” Female insert to complete the connection. The S-Connection is then fully grouted with high strength, PSA Connection Grout. Please refer to the PSA S-Connection Technical Document for more information.
