OBJECT To ascertain the conformance of Robertson's Barming/C:ahazon Plant, Concrete Aggregates with the requirements of ASTM C 33-03 "Standard Specification for Concrete Aggregates". .2 -C-M The properties of the concrete aggregates including grading and quality of fine and coarse aggregate are compared to specified requirements to determine the compliance of the aggregates. 3. LABORATORY The tests were performed by C_H.J., Incorporated, Colton, Cali fotnia. The laboratory is qualified to test concrete aggregates and is in compliance with ASTM E 329-03 "Standard Specification for Agencies Engaged in the Testing and/or inspection of Materials Used in Construction" and was examined by the Cement and Concrete Reference Laboratory of the National Institute of Standards and Technology in September 2005. 4.

Pretesting is required to determine the appropriate addition rate for Type A and Type D perfornnance, Optimum addition depends on the other concrete mixture com- ponents, job conditions, and desired performance ch aracter. i,sties. @lispensing Equipment A complete Une of accurate, auto- matic dispensing equipment is available, WRDA 64 may be introduced to the mix on the sand or in the water. Compatibility with Other Admixtures WRDA 64 is compatible in con- crete with all air -entraining admixtures such as Darer' 11 AEA and Daravair'. Due to the slight air -entraining properties of. WRDA 64, itself, the addition rate of air -entraining admixture may be reduced by about 25%. EACH ADMIXTURE SHOULD BE ADDED 5FPARATELY. While WRDA 64 contains no calcium chloride, it is compatible with cal- cium chloride in concrete mixes. Again, each should be added sep- arately. Packaging WRDA 64 is available in bulk, delivered by metered tank trucks, and in 210 L (55 gal) drums. It will .freeze at about -2'C (28'F), but will return to full strength after thawing and thorough agitation. Architects' Specification for Concrete WateaReducing Adrnixfure Concrete shall be designed in accordance with ACI Standard Recommended Practice for Selecting Proportions for. Concrete, ACI 211. The water -reducing (or water.- reducing and retarding) admix- ru.re shall be WRT)A 64, as manufactured by Grace Construction Products, or. equal. The admixture shall not contain calcium chloride. It shall be used in strict accordance with the man- ufacturer's teconimendations. The admixture shall comply with ASTM Designation C 494, Type A water -reducing (or Type D water -reducing and reta.tdi-ng,) admixtures. Certification of com- pliance shall be made available on request. The admixture shall be considered part of the total water The admixture shall be delivered as a ready -to -use liquid product and shall require no mixing at the batching plant or job site. 11► Vlslt our web sHe at www.graeeeonsfructlon.eom tI primed an recycled paper W, R.
