EVALUATION ON COMPRESSIVE STRENGTH OF PAVER BLOCK BY USING GEOPOLYMER
Publication Date : 12/03/2019
Paver block has been always one of the most used material in the construction sector. This content has been encouraged the development and use of new building materials such as Geopolymer. In this concrete, the cement is totally replaced by fly ash and alkaline solution to act as a binder in the concrete mix Geopolymer concrete achieve strength, an experimental investigation has been carried out for the geopolymer concrete and the mix design procedure is proposed of the quantity of fly ash, quantity of water, grading of fine aggregate, fine to total aggregate ratio, and sodium silicate to sodium hydroxide solution ratio. Sodium silicate solution and sodium hydroxide solution having various concentration (8M, 10M, and 12M) were maintained constant throughout the experiment. Water to geopolymer binder ratio of 0.35, alkaline solution to fly ash ratio of 0.61 and sodium hydroxide to sodium hydroxide ratio 1:1 of by mass were fixed on the basis of compressive strength. The temperature of oven heating was maintained at 70 °C for 24 hour duration and tested. It is observed that the results of compressive strength are well match with the required degree of compressive strength. Keywords: Compressive strength, Crusher Dust, Fly ash, Super plasticizer, coarse aggregate.
