2.1.2.4
Fine Aggregate Grading and Moisture Content
The fine aggregate or each fine aggregate shall have its sieve analysis and
fineness modulus determined in accordance with ASTM C 136 and COE CRD-C 104,
respectively. The moisture content shall be determined with an electric
moisture meter that shall be in accordance with COE CRD-C 143. When in the
Contracting Officer's opinion the electric moisture meter is not operating
satisfactorily, the moisture content shall be determined in accordance with
either ASTM C 70, ASTM C 566, or COE CRD-C 112.
2.1.2.5
Coarse Aggregate Grading and Moisture Content
Each size group of coarse aggregate shall have its sieve analysis
determined in accordance with ASTM C 136. The moisture content of each
size group of the coarse aggregate shall be made in accordance with ASTM C
566 or COE CRD-C 112.
2.1.3
Chemical Admixtures
Admixtures shall comply with the following.
2.1.3.1
Air-Entraining Admixture
The air-entraining admixture shall conform to ASTM C 260 and shall
consistently cause the concrete to have an air content in the specified
ranges under field conditions.
2.1.3.2
Accelerating Admixture
Accelerators shall meet the requirements of ASTM C 494/C 494M, Type C or E,
except that calcium chloride or admixtures containing calcium chloride
shall not be used.
2.1.3.3
Flowing Concrete Admixtures
Other chemical admixtures for use in producing flowing concrete shall
comply with ASTM C 1017/C 1017M, Type I or II. These admixtures shall be
used only if the proposed admixture shows no deleterious effects when used
with all other project materials during mixture proportioning studies.
