EH 188 is an auxiliary injecting substance (EN 934-4:T2) which we supplied before under the name of Tricosal 183 which can beapplied to manufacture a high-quality injecting mortar with a extreme high flowability. Because the characteristic substances of the normal auxiliary injecting substance have been improved in quality, EH 188 has more favourable passage speeds and greater strengths and it prevents bleeding and reduces the need for water
During manufacturing only high-quality aggregates are used, which meet the strictest requirements. During the production process as well as during the final stages these materials are extensively tested for quality, not only in our own laboratory, but also in independent acknowledged institutes.
|Packaging and storage|
|Jars containing 0.5 kg, packed in boxes of 25 kg or per 25 kg bags and 750 kg per pallet- Dry and frostproof, storage life 24 months in the original and closed packaging.|
|Refer to safety sheets.|
|The effect of Tricosal additive depends on various factors, such as local circumstances (weather, atmospheric humidity etc.); quality, brand, type and age of the cement applied; water-cement ratio; temperature of the mortar etc. The setting time may vary slightly, depending on the circumstances mentioned above. In general the processing time enables filling very long channels for prestressing steel completely, while injecting afterwards does not pose any problems either. The quantity allowed amounts from 0,20 till 1.50 % per kg cement at the maximum, 1 % per kg cement is recommended.””|
|Directions for use|
|EH 188 can only be mixed with a portland cement according NEN 3550 and a minimum strenth class of 32.5.
The injection grout must be mixed mechanicly with a suitable mixer.
All substances must be carefully added according to their weight and should, as a rule, be added in the order of water-cement-grout admixture.
It is recommended to add the grout admixture after the cement lime has been pre-mixed for 2 minutes.Mixing should be finished after 4 minutes at the latest.
If the grout is mixed to long, it is possible that under higher temperatures the grout may stiffen in the mixer.
To prevent segregation of the grout and the formation of clusters, it must be constanly mixed in the storage container.
