The Chem-Granite Super cartridgeconsistsofacylinderwithinacylinder.Theoutercylindercontainsepoxyresinandtheinnercylinderisfilledwithresinhardener.Using a dispensing gun, the resin andhardener components are simultaneouslyextruded into the mixing nozzle wherethey react and combine to form the highstrength Chem-Granite Super chemicalmortar.

Ananchorageisaccomplishedbyinjectingthe mortar into a drilled hole and thenrotating a steel rod into it until reachingthe bottom of the hole. The twistingmotion displaces air, distributes andpacks the mortar onto the surfaces ofthesteelrodandthewallofthehole.Themortar hardenswithinminutes to solidlyand permanently bond the steel to thesurroundingsubstrate.

The critical spacing and edge distances shown above are the minimum required to achieve full load capacity. Where actualdistances are less than ccr and scr, the loads must be reduced by a percentage corresponding to the percentage of reduction in critical spacing/distance. The capacity of a group of 2 or

more anchors shall be determined by the capacity of the mostunfavourably positioned anchor. In example – Fig. 2 – above, the most unfavourably placed anchor is Anchor #4 being affected by twoedgesandtwospacings.
