compressive strength of flyashbased geopolymer concrete

The Relationship of NaOH Molarity, Na2SiO3/NaOH Ratio, Fly

Geopolymer, produced by the reaction of fly ash with an alkaline activator (mixture of Na2SiO3 and NaOH solutions), is an alternative to the use of ordinary Portland cement (OPC) in the construction industry. However, there are salient parameters that affecting the compressive strength of geopolymer. In this research, the effects of various NaOH molarities, Na2SiO3/NaOH ratios, fly ash

Effect of Sulphuric Acid on Compressive Strength of Fly

In curing of concrete at room temperature ambient curing has been endorsed. To evaluate strength parameters, compressive strength test is directed at the duration of 28 days and as a measure of durability, acid attack test is conducted on specimens that are immersed in 5%H2SO4 solution for a period of 30, 60 and 90 days.
