(4) When ‘a’ is less than 20.0 cm but greater than 17.0 cm for 15.0 cm specimen, or less than 13.3 cm but greater than 11.0 cm for a 10.0 cm specimen. Where, b = measured width in cm of the specimen, d = measured depth in cm of the specimen at the point of failure, l = length in cm of the span on which the specimen was supported and, p = maximum load in kg applied to the specimen
d) Result obtained First take the trial test of mix-design and in this test cannot add the Alccofine. After 28 days get this result. This test is only for the Mix-design clarification. After 28 days getting compressive strength of cube 31 N/mm2. In this comparative study adding Alccofine 5%,10%,15% and 20% and getting result. After the result getting maximum strength in 10% add Alccofine. Alccofine material density is very low. That’s way getting minimum strength in 20% add Alccofine.
