Accelerated Pozzolanic Strength Activity Index with Portland Cement
Use the applicable section on strength activity index with Portland cement of Test Methods C 311, except change to reflect testing at constant water to cementitious materials ratio. Prepare test specimens from the batch proportions below, molding three cubes from both the control mix and the test mix.
Control Mixture:
500 g of portland cement,
1375 g of graded standard sand, and
242 mL of water.
Test Mixture:
450 g of portland cement,
50 g of silica fume,
1375 g of graded standard sand, and
242 mL of water.
X grams of dry high-range water reducer, meeting Specification C 494 Type F, required to produce a flow of 100 to 115%. Add the high-range water reducer directly to the mixing water in the mixing bowl. Then add the cement or the cement-silica fume mixture and start the mixing cycle.
