This document discusses a research study on using waste glass powder as a partial replacement for cement in concrete. The objectives were to increase workability, compressive strength, and lighten the concrete, while also reducing landfill waste. Glass powder replaced up to 30% of cement in the concrete mixes. The results showed that mixes with glass powder had higher workability and only slightly lower compressive strength compared to standard mixes. The glass powder also lightened the concrete. Therefore, the study concluded that using waste glass powder in concrete is an effective way to increase sustainability while maintaining adequate performance properties.

1. Performance of Using Waste Glass Powder in
Concrete As Replacement Of Cement
ANANTH KRISHNA K P

2. INTRODUCTION
As we know now a days ,most of developing country facing
shortage of post consumers disposal waste site and it has
become very serious problem. For this reason, regenerating
and using waste product as resources prevents
environmental pollutions.

3. In this research post consumer waste glass is considered. Instead
of Waste glass ending up as landfill it is been used as replacement
for cement. As it can’t be dissolved by natural or normal
recycling ways.
Most of the recovered waste glass is used by glass manufacturing
company in production of new glasses such as bottles etc..

4. Only certain category of glasses can be recycled due to high cost
of manufacturing. Manufacturers can only use waste glass that
has been pre-sorted by colour and type .
They are brown glass & clear glass , green glass can’t be used for
recycling.

5. CHEMICAL COMPOSITION OF VARIOUS COLOURED
GLASS

6. SIGNIFICANCE
It replaces upto 30% of cement in concrete mix.
It may give less cost of using this kind of admixture rather than
buying expensive admixtures .
Reduces landfill.
Reduces overall porosity & increases strength.
It can suppress alkali reactivity.
Shows better thermal insulation.

7. OBJECTIVES
Increases the workability of concrete mix.
Increases the compressive strength.
Lighten concrete.
Reduce landfill deposit.

8. MATERIALS
Cement:
Ordinary Portland cement of 33 grade conforming to
IS 8112 .
Fine aggregate:
Clean river sand whose max size is 4.75mm
conforming to grading zone II.

9. Coarse aggregate:
Machine crushed blue granite stone angular in shape.
Glass powder:
Glass powder ground in ball/ pulveriser for a period of
30 to 60 min resulting in particle size less than 150 μm &
sieved in 75 μm .

11. ANALYSIS AND DISCUSSION OF
COMPRESSIVE STRENGTH
Average of compressive strength at 7 days

12. Average of compressive strength at 14 days

13. Average of compressive strength at 28 days

14. ANALYSIS AND DISCUSSION OF CUBE
DENSITY
Average of cube density at 7 days

15. Average of cube density at 14 days

16. Average of cube density at 28 days

17. Analysis and discussion of workability

18. CONCLUSION
As a conclusion, all the objectives of this study are
achieved Concrete with using waste glass powder has a
very high workability from control sample.
This result achieved from the slump test that use of
waste glass powder were will increase the workability
of concrete.

19. From this research, using waste glass powder is giving
positive value even though the value compare to
standard mix it just less about 1N/mm.2
Concrete become lighter when mix with waste glass
powder. Therefore, concrete mix that using glass
powder is giving lightweight concrete.
