With Complete Solutions
A23.2-3C
1. |Scope |- |CORRECT |ANSWER✔✔-This |Test |Method |specifies |the |procedure |for |making |and |
curing |compression |test |cylinders |and |flexural |test |beams |from |samples |of |plastic |concrete. |
Procedures |for |both |field |and |laboratory |work |are |included.
ACI |- |CORRECT |ANSWER✔✔-American |Concrete |Institute
A23.2-3C
3. |Summary |- |CORRECT |ANSWER✔✔-This |Test |Method |is |used |to |cast |compressive |or |flexural |
strength |test |specimens |and |cure |them |on |site |prior |to |timely |transportation |to |the |laboratory
|for |subsequent |curing |and |strength |testing.
A23.2-3C
4. |Significance |and |use |- |CORRECT |ANSWER✔✔-This |Test |Method |specifies |the |standard |
procedure |for |making, |curing, |protecting, |and |transporting |concrete |specimens.
4. |Significance |and |use
If |the |specimens |are |made |and |standard |cured |as |specified |in |this |Test |Method, |the |resulting |
strength |data, |when |the |specimens |are |tested |in |accordance |with |the |relevant |test |method, |
may |be |used |for |the |following |purposes: |- |CORRECT |ANSWER✔✔-1. |acceptance |testing |for |
specified |strength;
2. |checking |adequacy |of |mixture |proportions |for |strength; |and
, 3. |quality |control
4. |Significance |and |use
If |the |specimens |are |made |and |field-cured |as |specified |in |this |Test |Method, |the |resulting |
strength |data, |when |the |specimens |are |tested |in |accordance |with |the |relevant |Test |Method, |
may |be |used |for |the |following |purposes: |- |CORRECT |ANSWER✔✔-1. |consideration |of |whether |
the |structure |is |able |to |be |put |into |service;
2. |comparison |with |test |results |of |standard |cured |specimens |or |with |test |results |from |various |
in |place |test |methods;
3. |adequacy |of |curing |and |protection |of |concrete |in |the |concrete |structure; |and |
4. |formwork |or |shoring |removal |time |requirements.
5. |Apparatus
5.1 |Moulds |for |compression |test |specimens: |- |CORRECT |ANSWER✔✔-Use |cylindrical |moulds, |
meeting |the |requirements |of |CSA |A23.2-1D, |having |nonabsorbent |surfaces |and |sufficiently |
rigid |to |hold |their |shape |during |the |moulding |of |the |test |specimens.
Do |not |use |cardboard |moulds |for |specified |concrete |strengths |greater |than |35 |MPa.
Lightly |coat |reusable |moulds |with |mineral |oil |or |other |suitable |non-reactive |form |release |
material |before |use.
5.3 |Tamping |rod
For |100 |mm |x |200 |mm |cylinders, |- |CORRECT |ANSWER✔✔-se |a |round |straight |steel |tamping |
rod |10 |+/- |1 |mm |in |diameter |and |between |450 |mm |and |600 |mm |in |length, |having |at |least |one
|end |rounded |to |a |hemispherical |tip.
5.3 |Tamping |rod
For |cylinders |150 |mm |in |diameter |or |greater |and |for |rectangular |moulds, |- |CORRECT |
ANSWER✔✔-use |a |round |straight |steel |tamping |rod |16 |+/- |1 |mm |in |diameter |and |not |less |
than |450 |mm |nor |more |than |600 |mm |in |length, |having |at |least |one |end |rounded |to |a |
hemispherical |tip.
