It is supplied as a ready-to-use dry powder requiring only the addition of water.\u003c\/p\u003e\n\u003cp\u003eDesigned for construction applications requiring higher performance, Class A Superstrength Grout combines low water requirements with high compressive strength. It provides high early strength and can be placed as a \u003cstrong\u003edry pack, trowellable or flowable grout\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eSuitable applications include \u003cstrong\u003ecolumn base plates, anchoring fixings, bolt holes, tilt-up panels, joints, underpinning and concrete repairs\u003c\/strong\u003e.

Add approximately 90% of the recommended water to the mixer first, followed by the dry powder. Mix for 2 minutes, then adjust the consistency with the remaining water. Mix until homogeneous for at least another 3 minutes.\u003c\/p\u003e\n\u003cp\u003eDo not mix for more than 5 minutes and do not remix. Do not mix more grout than can be placed within 20 minutes. Once mixing and placement have commenced, grouting should be carried out as a continuous operation.\u003c\/p\u003e\n\u003ch3\u003eApplication\u003c\/h3\u003e\n\u003cp\u003ePre-grout bolt holes level with the substrate to help maintain continuous grout flow. Pour from one side only to minimise voids caused by trapped air or excess pre-soaking water.\u003c\/p\u003e\n\u003cp\u003eMaintain a grout head at all times to achieve a continuous grout front. Place the mixed grout promptly and continuously, and finish the grout bed level with the underside of the baseplate.\u003c\/p\u003e\n\u003ch3\u003eYield\u003c\/h3\u003e\n\u003cp\u003eApproximate grout yield per 20kg bag:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDry pack:\u003c\/strong\u003e 10.2 litres, approximately 98 bags per m³\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrowellable:\u003c\/strong\u003e 10.6 litres, approximately 94 bags per m³\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlowable \/ pourable:\u003c\/strong\u003e 11.6 litres, approximately 86 bags per m³\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompressive Strength\u003c\/h3\u003e\n\u003cp\u003eAt the dry-pack water ratio of 2.0 litres per 20kg bag, typical compressive strength is \u003cstrong\u003e50 MPa at 1 day, 82 MPa at 7 days and 91 MPa at 28 days\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch3\u003eSurface Preparation\u003c\/h3\u003e\n\u003cp\u003eAll surfaces should be free from oil, grease and loose material.
