This document summarizes a research paper on geopolymer concrete, an eco-friendly construction material. It describes geopolymer concrete as a cementless material made by activating fly ash and slag using alkaline liquids instead of Portland cement. The objectives of the study were to produce a carbon dioxide emission-free cementitious material and evaluate the compressive strength of mixes with varying fly ash and GGBS contents. The results showed that geopolymer concrete gained strength within 24 hours at ambient temperature without water curing, and mixes with higher GGBS content achieved greater compressive strength, with the F60G40 mix attaining the maximum of 80.50N/mm2.

3. WHAT IS POLYMER CONCRETE ?
Geopolymer concrete is a new material that does not need the
presence of Portland cement as binder.
Instead ,activating the source materials such as fly ash that are
rich in Silicon(Si) and Aluminum (Al) using high alkaline liquids
produces binder for manufacturing concrete.

4. WHY WE USE ?
 The major problem that the world is facing today is the environmental
pollution.
 In the construction industry mainly the production of ordinary Portland
cement (OPC) will cause the emission of pollutants which results in
environmental pollution.
 The emission of carbon dioxide during the production of ordinary
Portland cement is tremendous because the production of one ton of
Portland cement emits approximately one ton of CO2 into the
atmosphere.
 In terms of global warming, the geopolymer concrete significantly reduce
the CO2 emission to the atmosphere caused by the cement industries

AGGREGATES

7.  The total volume occupied by fine and coarse aggregate is adopted as
77%.
 The alkaline liquid to fly ash and GGBS ratio is kept as 0.4.
 The ratio of sodium hydroxide to sodium silicate is kept as 2.5
 The cube specimens are taken of size 100 mm x 100 mm x 100 mm.
 In total 36 cubes were cast for different mix Id and the cube specimens
are tested for their compressive strength at age of 1 day, 7 days and 28
days respectively.
 A 12 Molarity solution was taken to prepare the mix. The cube
compressive strength was calculated for 12M solution for different mix
Id i.e. F90G10, F80G20, F70G30, and F60G40 (Where F and G are,
respectively.
 The Alkaline liquids used in this study for the polymerization process are
the solutions of sodium hydroxide (NaoH) and sodium silicate
(Na2Sio3).

9. TEST RESULTS
It was found that as
the age of the
concrete increases
the compressive

geopolymer concrete
is enhanced at
ambient temperature
without water curing.

10. TEST PROCEDURE :

12. Based on the results obtained in the experimental investigation, the following
conclusions are drawn.
 The geopolymer concrete gained strength within 24 hours at ambient
temperature without water curing.
 The necessity of heat curing of concrete was eliminated by incorporating
GGBS and fly ash in a concrete mix.
 The strength of geopolymer concrete was increased with increase in
percentage of GGBS in a mix.
 It was observed that the mix Id F60 G40 gave maximum compressive
strength of 80.50N/mm2.
