Placing
Do the correct methods of placing normally applied for concrete repairs as suggested and directed by Deltacrete technical team. Deltacon FS can be applied up to 120 mm thickness in a single application.
For section thicker than 120 mm and less than 300 mm, it is recommended to mix Deltacon FS with clean sands and graded aggregates in order to minimise internal thermal development.
The following mix design should be considered:
25 kgs Deltacon FS
4 – 4.5 litres of clean water
10.5 kgs of 6 to 12 mm aggregate
6.5 kgs of zone 2 sand
Trial mixes should be made in order to ensure the optimum addition of both water and aggregate.
STORAGE
Deltacon FS has a shelf life of 12 months if kept in a dry store in the original, unopened bags.
