Compressive Strength of Silica Fume Based Geopolymer Concrete

It reveals that there is an increase in the compressive strength when alkaline liquid ratio increases from 0.25 to 0.30 and 0.30 to 0.35 irrespective of age of concrete. It is also noted that for a particular AL/SF ratio there is an increase in strength with increase in Na 2 SiO 3 /NaOH ratio from 0.5 to 1.5 and 1.5 to 2.5 ratios. The rate of increase in compressive strength due to increase in

Compressive Strength Test of Concrete - Civil Engineering

Compressive Strength Test Idea: 1- Concrete is poured in the mould and compacted properly to reduce the amount of voids. 2- After 24 hours, moulds are removed and test specimens are then placed in water for curing. 3- After the specified curing period [3, 7, 28, 56, or 91 days], specimens are tested by the compression testing machine.
