Water Penetration:
VicRoads Geopave Concrete Materials Technology. Victoria, Aust.:
- "The HPI (Caltite) concrete has been found to outperform both conventional and SCM's (slag, silica fume)
concrete with far greater reductions in Volume of Permeable Voids (VPV).
- "Caltite is an excellent material for reducing the VPV of concretes"
British Board of Agrement (BBA):
- "The Everdure Caltite component is an aqueous, hydrophobic, pore-blocking ingredient that gives waterproofing,
pore-blocking, and enhanced durability properties to concrete in which it is incorporated."
- "In particular, test data and site observations indicate that (Caltite) waterproof concretes can be designed
to eliminate the passage of water and therefore waterborne materials, without the need for additional surface applied
membranes or protection."
- "The System can provide waterproofing for car park roof decks, work below dpc, swimming pools and other
similar situations. Everdure Caltite System forms a suitable alternative for compliance with ..BS 8007 :1987, BS
8102 :1990 and BS 8110 :Part 1:1985"
Taywood, UK:
- "The water repellency of CALTITE concrete was found to be unaffected by tidal immersion over a period
of up to 17 years."
National University of Singapore:
- "This mix (containing EVERDURE CALTITE) is thus recommended to make concrete 'water-tight'"
University of Toronto:
- "The mix containing EVERDURE CALTITE admixture showed a marked improvement in the ability of concrete
to endure severe environments."
Queen's University, Belfast:
- "Amongst the three modified concretes covered in this paper, CALTITE concrete was observed to be the most
efficient in reducing the water permeability."
Chloride Penetration:
Roads & Traffic Authority - New South Wales (Aust.) (CTI Consultants):
- "The (Caltite) hydrophobic pore-blocking additive performed very well, especially at the deeper intervals
where chloride reductions in excess of 97% were recorded.
- These results are better than those for the organo-silanes, probably due to the presence of the hydrophobic
additive throughout the concrete, rather than only in the outer layer as is the case for the post-applied sealers."
- "Based on these results, (Caltite) can be used to protect concrete against moisture and chloride ingress
under conditions of atmospheric exposure."
Engineering and Water Supply Department, Australia:
- "(EVERDURE CALTITE) can be of enormous benefit in sustaining and prolonging the life of a concrete structure."
City of Glenelg, Australia:
- "Recent inspection shows the CALTITE concrete to be still quite sound, whereas the normal concrete shows
severe aggregate exposure and areas of cracking due to steel corrosion."
Taywood, UK:
- "Cores taken from CALTITE concrete exposed to tidal immersion for up to 17 years showed no signs of corrosion
of the embedded reinforcing bar and little surface erosion of the cement matrix."
TROW, Canada:
- "The EVERDURE CALTITE mix meets the performance expectations of a latex modified concrete with regard
to chloride penetration."
Institute TNO, Netherlands:
- "Instrusion of chlorides by diffusion of seawater transport is diminished by the use of CALTITE."
Chemical Attack:
Hardman Australia:
- "Our EVERDURE CALTITE Joint-free acid proof floor is now 19 years old in constant use - which compares
extremely well with the life of our ordinary earliest floors."
Coal Products Limited, UK:
- "I can advise that your EVERDURE CALTITE SYSTEM concrete is still in a satisfactory condition. Surrounding
bases cast using a grade 30N/mm² concrete with SRC are now showing extreme degradation due to continuous acid
attack."
Gudgeon, Mott, Hay, Anderson, Singapore:
- "We are pleased we used your "CALTITE" and other additives for these (fertiliser) floors and
we must compliment you on a product that more than lives up to your specification."
Brisbane City Council, Australia:
- "Both samples suffered from sulphide attack, but the sample containing CALTITE and PLASTET No. 2 suffered
much less attack than did the ordinary 20MPa concrete".
Sandberg, UK:
- "The CALTITE specimen exhibited significantly less acid attack in terms of both depth of attack and area
of deterioration."
Other Properties:
Taywood Engineering UK Ltd:
- "Compared with conventional concretes, the values of (electrical) resistivity were very high, particularly
after soaking. For concrete with a typical moisture content of 3-5%, resistivity values are in the range of 50
k.ohm.cm. The Caltite concrete had a resistivity in excess of 1,000 k.ohm.cm, i.e. more than 20 times higher than
conventional concrete."
Ready Mixed Concrete, Hong Kong:
- "We have carried out exhaustive laboratory tests on concrete containing CALTITE and have found it to have
no detrimental effects on strength development."
University of Liverpool:
- "The resistivity measurements show that the modified (EVERDURE CALTITE) concrete is considerably less
conductive than the unmodified concrete."
Sandberg, UK:
- "The expansion of the prisms of CALTITE concrete under freeze-thaw conditions was considerably lower than
that of the control at all times during the 50 cycle test; the visible spalling was also considerably less and
occurred later than on the specimen of control concrete."
*Ask your Cementaid representative for a copy of the certificate.
- "Petrographic analysis of concrete containing a known reactive aggregate showed no reaction in concrete
containing the EVERDURE CALTITE System when subject to wetting and drying cycling."
- "Significantly greater resistance to carbonation."
- "The System has no detrimental effects on the properties of the cured concrete."
- "Site observations and other data show that the properties of concrete containing EVERDURE CALTITE have
been maintained for up to 30 years."
