1 MASTERFLOW 830. cementitious high strength non- shrink precision grout DESCRIPTION PERFORMANCE DATA. MASTERFLOW 830 is a non shrink precision grout Strength Strength Development formulated to provide ample working time when mixed and The strength of the grout is often the determining factor in placed at flowable consistency. It contains specially graded deciding when loads can be put on structural members or natural aggregate and provides high early and ultimate machinery. The strength of the grout is dependent on the compressive strengths. MASTERFLOW 830 is normally amount of mixing water used, ambient and substrate placed at a flowable consistency to completely fill voids temperature, curing and age of the hardened grout .

2 Between 10mm and 100mm. Thicknesses greater than Typical rate of strength development when placed at 100mm are possible with the addition of aggregate. flowable' consistency at 23 C. RECOMMENDED FOR Age at Test Compressive Strength All precision, non- shrink grouting applications with 1 day 25 MPa clearances of 10mm or more including: 3 days 42 MPa Critical equipment baseplates, soleplates and 7 days 55 MPa columns. 28 days 65 MPa Precast wall panels, beams, columns, structural Test Method: Appendix A. building members and curtain walls. For applications requiring higher compressive strength, Patching poured in place concrete structures refer to MASTERFLOW 870, 870 , MASTERFLOW 880 or honeycombing, using preplaced aggregate BASF Construction Chemicals range of epoxy grouts.

For situations requiring dry pack' (damp pack). consistency produces approximately litres ( cubic application, refer to MASTERFLOW 95 or metres) of grout . MASTERFLOW 500. 500. Water Demand SHELF LIFE. Actual amount of water required will depend on desired consistency for the job and temperature (both ambient and MASTERFLOW 830 has a shelf life of approximately 12. grout ). months when stored in a cool dry environment. For any given consistency more water will be required at PACKAGING. high temperatures, and less at low temperatures.

MASTERFLOW 830 is not toxic, but contains Portland As a guide, 20kg of MASTERFLOW 830 mixed at 23 C cement. It has an alkaline nature and thus can be irritating requires approximately litres of water to provide the to skin and eyes. Wear simple dust masks and gloves recommended lateral flow when using a tilting barrel or when handling. Wash off splashes of grout with clean paddle type mixer. When using a grout stirrer, this water water. If irritation persists, seek medical advice.
