Free Flowing Cementitious Micro Concrete
PRODUCT DESCRIPTION; A cementitious free flowing and self-compacting concrete, based on non-reactive aggregates, low alkali Portland cements with selected admixtures to produce a chloride free concrete which contains no corrosive metallic additives. Nugrout Flowable Concrete is designed for structural repair situations and complies with the requirements of the Department of Transport Standard BD27/86 Clause 4, as well as with the requirements of BS EN1504 Part 3 Class R4.
Has controlled expansion and is non-shrink.
Excellent early compressive and flexural strength.
Designed to facilitate cathode protection.
Material can be pumped, poured & vibrated.
Excellent bond strength to steel and concrete.
Requires only addition of clean water.
Excellent flow and placement characteristics.
Resistant to vibration and impact.
Complies with requirements of EN1504 Part 3 Class R4. Applications
Repairs to in-situ bridge decks and piers.
Repairs of reinforced concrete structures.
Bedding of precast beams.
Grouting of machinery and turbines etc.
Highway & Rail network structures
Approximate yield is 12.7 litres per 25kg unit.
Mixing may be carried out in a standard barrel mixer or forced action mixer of a size suitable to produce the quantity of material required and without leaving any residual unmixed material. The mixing of part bags is not recommended. The mixer drum is to be clean and free from the remains of the previous mixes. Thoroughly wet the inside of the mixer drum and drain off any excess water. Measure out the mixing water and place approximately two thirds of this into the mixer drum. With the mixer rotating, add the full contents of the pack and allow to mix till a stiff consistency is obtained. This is necessary to eliminate any unmixed material. Add all or part of the remainder of the water to achieve the desired consistency and allow to mix for a further 1-4 minutes, depending upon mixer. Pour the mix into containers and allow to de-air for 3-5 minutes. This will not be necessary if pumping. Use mix as required.
Nugrout Flowable Concrete Nugrout Flowable Concrete should be placed by pouring, remembering flow-ability decreases with time. Always mix enough material to complete placing in one uninterrupted pour. Place the product from one side only, so as to avoid entrapped air and to ensure continual free flow of the material. Where formwork is involved it is essential that it is thoroughly sealed to prevent concrete loss and it should be coated with Chemlease to obtain an easier release.
Nugrout Flowable Concrete The addition of excess water to “aid-flow-ability” should be avoided as this could cause segregation of the mix and inhibit pumping. To aid pumping, the water addition may be reduced slightly by an experienced operator. Please contact our technical team for further information regarding specific applications.
LOW TEPERATURE WORKING:
Concreting should not take place in temperatures below 5°C unless steps have been taken to protect grouted areas in these conditions. At temperatures below 10o C it is advised Nugrout Flowable Concrete is stored at 15-20°C for a minimum of 24 hours and that the mixing water should be warm, 20-25°C
