GRANITE SEA WALL REPAIR WITH KALMATRON® KF-SEA ADMIXTURE
JOB DESCRIPTION
• Mortar prepared with:
1 part of Portland Type I; II cement
3 parts of unwashed sea sand and gravel from a beach
11 Kgs of KF-SEA per 1 m3 of mortar
water to cement ratio is 0.36 with water taken from the Tasman Sea
• Washing of wall with sea- water.
• The thickness of application is up to 300 mm thick on the outside of sea wall and 150 mm thick on the inside.
• Washing of repaired wall with water from ocean on third – seventh day
• After all KALMATRON® KF-F was applied as a coating for concrete coloration.
Summary of test results provided by “Geotech Pty., Ltd.” on the 28th day is as follows:
Density is 2,170 Kg/m3 exceeds the standard average of 1,100 Kg/m3 by almost twice.
Shrinkage is 0.16% is lower than for regular mortar at least by four times;
Compressive strength 45.6 MPa classifies that mortar as high dense concrete.
The dosage of KALMATRON® KF-SEA admixture was chosen after comparative testimony of a few ones and relevant to mineralogical content of Australian Shores of Pacific Ocean and Tasman Sea only.
After all the structure was painted with KALMATRON® KF-F to provide additional protection from climate corrosion.
