ACI 515.1 R-79 (Revised 1985)

A Guide to the Use of Waterproofing, Dampproofing, Protective, and Decorative Barrier Systems for Concrete Reported by ACI Committee 515 Byron I. Zolin, Chairman Warner K. Babcock Arthur E. Blackman, Sr.

Donald E. Brotherson Robert W. Gaul Clark R. Gunness Kenneth A. Heffner A. L. Hendricks James E. Kubanick Dorothy M. Lawrence Stella L. Marusin Charles J. Parise Charles 0. Pratt Andrew Rossi, Jr.

Donald L. Schlegel Lawrence E. Schwietz The revising committee is listed at the end of the document.

This Guide updates and expands the scope of the committee report "Guide for the Protection of Con-crete Against Chemical Attack by Means of Coatings and Other Corrosion Resistant Materials," which ap-peared in the December 1996 ACI JOURNAL. The pre-vious Guide has been revised and is found in Chapter 6 of this Guide entitled "Protective Barrier Systems." In addition, there are new chapters on "Waterproofing Barrier Systems," "Dampproofing Barrier Systems," and "Decorative Barrier Systems."

A separate chapter on conditioning and surface preparation of concrete is included because it is rele-vant to all the other chapters.

This Guide is not to be referenced as a complete unit.

Keywords: abrasive blasting; acid treatment (concrete); acid resistance; ad-hesion; asphalts; chemical attack; chemical cleaning; coatings; concrete bricks; concretes; detergents; emulsifying agents; epoxy resins; finishes; furan resins; glass fibers; inspection; joint sealers; latex (rubber); mortars

[materials); paints; phenolic resins; plastics, polymers, and resins; polyester resins; polyurethane resins; protective coatings; repairs; sealers; silicates; sulfur; surfactants; temperature; tests; vaporbarriers; waterproofing.

Foreword ACI Committee 515 was organized in 1936 and pub-lished a report "Guide for the Protection of Concrete Against Chemical Attack by Means of Coatings and Other Corrosion Resistant Materials," in the De-cember 1966 ACI JOURNAL. William H. Kuenning was chairman when this Guide was published. Albert M.

Levy was chairman from 1974 to 1977 when some of the information, found in the chapters on "Water-proofing Barrier Systems" and "Dampproofing Bar-rier Systems," was developed.

FM 5.3 Exhibit 2 page 7 of 7 SURFACE BARRIER SYSTEMS 515.1R-11 Key to special notations-Table 2.5.2 Sometimes used in food processing or as food or beverage ingredient. Ask for advisory opinion of Food and Drug Administration regarding coatings for use with food ingredients.

a Waters of pH higher than 6.5 may be aggressive if they also contain bicarbonates. (Natural waters are usually of pH higher than 7.0 and seldom lower than 6.0, though pH values as low as 0.4 have been reported. For pH values below 3, protect as for dilute acid.)

b Frequently used as a deicer for concrete pavements. If the concrete contains too little entrained air or has not been aged more than one month, repeated application may cause surface scaling. For protection under these conditions, see "deicing salts."

c Carbon dioxide dissolves in natural waters to form carbonic acid solutions. When it dissolves to extent of 0.9 to 3 parts per million it is destructive to concrete.

d Frequently used as deicer for airplanes. Heavy spillage on runway pavements containing too little entrained air may cause surface scaling.

e In addition to the intentional fermentation of many raw materials, much unwanted fermentation occurs in the spoiling of foods and food wastes, also producing lactic acid.

f Contains carbonic acid, fish oils, hydrogen sulfide, methyl amine, brine, other potentially reactive materials.

g Water used for cleaning coal gas.

h However, in those limited areas of the United States where concrete is made with reactive aggregates, disruptive expansion may be produced.

n Composed mostly of nitrogen, oxygen, carbon dioxide, carbon monoxide, and water vapor. Also contains unburned hydrocarbons, partially burned hydrocarbons, oxides of nitrogen, and oxides of sulfur. Nitrogen dioxide and oxygen in sunlight may produce ozone, which reacts with some of the organics to produce formaldehyde, peracylnitrates, and other products.

o These either contain chromium trioxide and a small amount of sulfate, or ammonium chromic sulfate [nearly saturated) and sodium sulfate.

p Many types of solutions are used, including (a) Sulfate-Contain copper sulfate and sulfuric acid.

(b) Cyanide-Contain copper and sodium cyanides and sodium carbonate.

(c) Rochelle-Contain these cyanides, sodium carbonate, and potassium sodium tartrate.

(d) Others such as fluoborate, pyrophosphate, amine, or potassium cyanide.

q Contains lead fluosilicates and fluosilicic acid.

r Reference here is to combustion of coal, which produces carbon dioxide, water vapor, nitrogen, hydrogen, carbon monoxide, carbo-hydrates, ammonia, nitric acid, sulfur dioxide, hydrogen sulfide, soot, and ashes.

u Porous concrete which has absorbed considerable molten paraffin and then been immersed in water after the paraffin has solidified has been known to disintegrate from sorptive forces.

v Contains nickelous chloride, nickelous sulfate, boric acid, and ammonium ion.

w May contain various mixtures of blood, fats and oils, bile and other digestive juices, partially digested vegetable matter, urine, and manure, with varying amounts of water.

x Usually contains zinc sulfate in sulfuric acid. Sulfuric acid concentration may be low (about 6 percent in "low current density" process) or higher (about 22-28 percent in "high current density" process).
