5.2.5 Materials and Materials Testing Four basic materials systems make up the primary containment:
Concrete and reinforcing steel for the base slab, a.
cylindrical-conical wallt and diaphragm slab.
b.
Steel plate for the.inet.
Steel for the head, penetrations, and their c.
anchorages, d.
Structural steel for support of floor and platforms.
Cetailed specifications and working drawings for these mat 2 rials and their installation are of such scope as to assure that the quality of work is commensurate with the necessary integrity of the primary containment.
5.2.5.1 Materials 5.2.5.1.1 Concrete Concrete for the primary containment has a specified compressive strength of 4,000 psi at 23 days.
l a.
Cement is Type II, as specified in " Standard Speci-fications for Portland Cement", ASTM Designation C-150, and is tested to comply with ASTM C-114.
b.
Aggregates will conform to ASTM Designation C-33 except for the gradation of the high density aggregates which will be well graded to produce a workable mix that meets all shielding requirements.
Water for mixing concrete is clean and free from c.
any deleterious amounts of acid, alkali, salts, oil, sediment, or organic matter.
d.
Admixtures shall conform to ASTM C-260 for air entraining agents, and ASTM C-494 for water reducing agents.
e.
Concrete mixes are designed in accordance with ACI 613, using materials qualified and accepted for this work.
Trial mixes are tested in accordance with applicable ASTM Codes as indicated below:
5.2-13 August 1980
LGS 5.
Section 3.5.l(a) of the 1974 Supplement to ACI 318-71 applies in lieu of Section 3.5.l(a) of ACI 318-71.
a s 6.
The following requirements apply in lieu of the first sentence of Section 4.1.4:
F'c for 5000 psi design strength concrete shall be based on tests of 90 days.
F'c for all other concrete design strengths shall be based on 28 day tests.
7 The following requirements apply in lieu of the last sentence of Section 4.3.1:
Each strength test result shall be the average of wo cylinders from the same sample tested at 28 days for concrete with a design strength of 4000 psi or less and 90 days for concrete with a design strength of 50C0 psi.
