Mechanical Strength Optimization of Geopolymer Concrete Pavement Blocks
In this present study, sincere efforts are devoted to induce a proper design mix guideline for GPC with the primary focus on attending the maximum compression testing value in a reduced cost-effective way for various ratios of alkaline solutions to solid binder materials. In this present investigation, locally purchasable low calcium fly ash (FA) and ground granulated blast furnace slag (GGBS) as the solid dust materials, combined solution of NaOH and Na2SiO3 as an alkali solutions and graded aggregates are mixed on the basis of the guidelines of Indian standards (IS-10262:2019).
This paper focuses on the development of geopolymer concrete Coro-lock paver blocks by a combination of FA with GGBS as a proportion of 40–60, 50–50, 60–40% and alkali activator solution (AAS)-to-binder (B) ratio (AAS/B) is ranged from 0.42 to 0.45%. This research presents the results of compression testing values, density, and water absorption of GPC with different ratios of constituents. Further, the cost-effectiveness of GPC with respect to standard OPC is also established.
Correlation between the various proportions of FA-GGBS and 28-days compressive strength of geopolymer concrete Coro-lock paver blocks is experimented to predict the rational method of design mix for GPC. In the experimental results, 28-days compressive strength of geopolymer concrete Coro-lock paver blocks is observed as high as 49.5 MPa.
