RESULT:
DISCUSSION: Cover the following point:
NOTE:
I. Effect of variable of fine aggregate on
the density of concrete mix. II. Effect on workability when w/c ratio is kept
constant.
III. Effect of above factors on strength.
IV. Comments on results obtained.
1.
Prepare
one 15 cm. Cube for each mix. 2. Take materials in required proportion. 3. Test
after curing at an age of 28 days.
