Mastermix HSR – Acid resistant quick setting concrete solution.
Product Introduction and Description
Managing high stress points can determine the long term success of your project. HSR is a high performance product offering fast curing times combined with very fast high compressive strength characteristics. It is resistant to acid attack and can be trowelled to a feathered finish when Multi Cote is used as a primer. HSR has a wide range of uses where fast setting times are crucial. It is an Ideal product for resetting hinges, pins and bolts that are set in concrete and, with discussion with our technical department, may be used to repair and protect concrete members in both prestressed and reinforced concrete structures. ‘HSR’s acid resistant characteristics enable it to be used in all geothermal and marine environments. Just how fast and how strong you ask? HSR sets in 7 minutes and after 3 hours achieves a compressive strength of 20MPa, 30MPa in 24 hours and 50MPa when fully cured in 28 days!

HSR is a fast setting, very fast high compression product which has a wide range of applications.

Product Performance As part of our commitment to developing the best products for your projects, Mastermix has maintained a 20 year history of rigorous testing via internationally recognised laboratories. We pay top dollar to put our products to the test so you don’t have to. OPUS Results: Independent laboratory tests produced the following results have been carried out under the following test condition, DIN 12808-30 and NZ Standards 3112 and conforms to NZ Standards 4201:2001.+20MPa in 3hours +30MPa in 24hrs +40MPa in 7 days +50MPA in 28days +Flexural strength 5MPa Acid resistance – no change when immersed for 56 days at ph 3.5 @ 45ºC with minimal shrinkage >0.05%
Packaging Packed in 20kg pails, the shelf life is approximately 3 months when kept in cool dry conditions.
Instructions Prepare the surface of the substrate to ensure it is clean of: 🗸 Grease 🗸 Loose and weak materials 🗸 Other foreign matter 🗸 Rotate pail end for end before opening as settling may occur. Measure 200mls of clean water to 1kg of ‘HSR’ into a clean container, mix thoroughly ensuring the water is mixed evenly through the product. If necessary, add a small amount of water to achieve the desired consistency. Once finished DO NOT REWORK. Mixing for use as a water plug Mix using less water and knead by hand to a consistency of putty. When product gets warm, plug the hole. In all cases do not mix any more than you can place before the product sets. The ambient temperature affects the curing time of HSR. It is best used in temperatures of between 7°C and 25°C. The water content will also affect the curing time. Once mixed correctly ‘HSR’ will set in 7 minutes at an ambient temperature of 16°C
Coverage & Performance ‘HSR’ has a wide range of uses where fast setting times are crucial. This includes resetting of manhole covers, repairs to concrete roads, kerbs and paths. Ideal product for resetting hinges, pins and bolts that are set in concrete and, with discussion with our technical department, may be used to repair and protect concrete members in both prestressed and reinforced concrete structures. ‘HSR’s acid resistant characteristics enable it to be used in all geothermal and marine environments.
Warranty As part of our commitment to delivering the best customer experience throughout the project lifecycle, Mastermix Director Steve Douglas personally reviews each warranty request of the Mastermix product line. Warranty periods are awarded at our discretion and will only be considered where approved Mastermix product applicators are used. Often times we EXCEED the required project warranty period by up to 43 years!
PRODUCT SUMMARY

20MPa in 3hours: 30MPa in 24hrs; 40MPa in 7 days: 50MPA in 28days
Flexural strength 5MPa
Acid resistance – no change when immersed for 56 days at ph 3.5 @
45ºC
Shrinkage >0.05%
‘HSR’ has been tested in both Europe and New Zealand, the above
results have been carried out under the following test condition, DIN
12808-30 and NZS 3112 and conforms to NZS 4201:2001.

When used as a repair medium all surfaces should be dry, free of dust and loose material.
The ambient temperature affects the curing time of ‘HSR’. It is best used in temperatures of between 7°C and 25°C. The water content will also affect the curing time.
Once mixed correctly ‘HSR’ will set in 7 minutes at an ambient temperature of 16°C
