Crystal Lok® Chemical Defense
Crystal Lok® waterproofs and treats to prevent chemical and liquid attack on and deterioration to concrete structures where Portland cement is the principal cementitious component of the concrete structure.
Crystal Lok® treated surfaces resists attack by these compounds and aids protection of imbedded structural steel.

The list below is a compilation of chemical compounds for which Crystal Lok® silicate is a recommended treatment by research of: 
        1.   “Compilation Report on Cement and Concrete Application Testing 1995-1997” The Intercollege Materials Research Laboratory;  The Pennsylvania State University.                 Barry E. Sheets, Michael R. Silsbee, Tanya Baker

ACIDS
acetic, < 10%
acid waters with pH of 6.5 or less. (
Disintegration of concrete increases as pH decreases.)
boric
carbolic
carbonic
chromic, 5 % - 50%. (In porous concrete it attacks steel. Steel corrosion may cause concrete to spall.)
formic, 10% - 90%
Humic (disintegrating plant waste,ie compost)
hydrochloric - 10% - 37%. (Causes rapid disintegration, including steel.)
phosphoric, 10% - 85%
tannic

SALTS & ALKALIS
bromide, sodium
dichromate sodium
potassium
nitrates of lead, magnesium, potassium,
sodium, & ammonium

nitrite of sodium
Persulfate potassium
•sulfite of sodium
thiosulfate of sodium

PETROLEUM OILS
gasoline, kerosene, light oil above 35° Baume, ligroin,lubricating oil, machine oil, mineral spirits
benzol (benzene), cumol (cumene),
toluol (toluene), xyol(xylene)

creosote, cresol, dinitrophenol,
phenol 5% - 25%


SOLVENTS AND ALCOHOLS
carbon tetrachloride
ethyl alcohol
Ethel ether, methyl alcohol
t-butyl alcohol
trichloro-ethylene
acetone
carbon disulfide
glycerin (glycero)
ethylene glycol. (Used as deicer for airplanes. Spillage on concrete may cause surface scaling.)

FATS AND FATTY ACIDS
fish oil
neatsfoot oil, tallow and tallow oil
beef fat, lamb fat
lard, lard oil

VEGETABLE OILS
turpentine
almond, china wood, linseed, olive, peanut,
poppy seed, soybean, tung, walnut

margarine
castor, cocoa bean, cocoa butter, coconut, cottonseed, mustard, rapeseed

MISCELLANEOUS
ashes - (Sulfides and sulfates leach out and attack concrete.)
bleaching solutions
brine-see specific chemicals above
buttermilk - lactic acid
carbon dioxide-(May cause permanent shrinkage of concrete, or carbonation. Steel imbedded in carbonated concrete is prone to corrosion.)
chlorine gas
cider
coal
coke corn syrup - glucose
fermenting fruits, grains, vegetables, or extracts
formaldehyde - 37% (formalin)
fruit juices - (Sugars and hydrofluoric and other acids cause disintegration on concrete.)
hydrogen sulfide
iodine

lead refining solution
lignite oils
manure
mine waste water . (Acids present disintegrate concrete and attack steel.)
molasses
nickel plating solutions
ores - (Sulfides leaching may oxidize to sulfuric acid or ferrous sulfate. Treatment stops leaching. )
sauerkraut
seawater -
(Disintegrates concrete with inadequate sulfate resistance and steel is attacked in porous or cracked concrete.)
sugar (sucrose)
sulfur dioxide
tanning bark
tanning liquor
water, soft (75 ppm of carbonate hardness)
wine
