Civil Important Topic Glass material is used as fine aggregates Discus

1. Introduction
 Glass is a transparent material produced by melting a mixture of
materials such as silica, soda ash, and CaCO3 at high
temperature followed by cooling where solidification occurs
without crystallization.
 Glass is widely used in our lives through manufactured products
such as sheet glass, bottles, glassware, and vacuum tubing.
 waste glass that is crushed and screened is a strong, safe and
economical alternative to sand used in concrete.
 Crushed glass or cullet, if properly sized and processed, can
exhibit characteristics similar to that of gravel or sand.

2. Materials & Method
 In order to study the effect of waste glass as partial cement replacement on
the strength of concrete, fine aggregate and coarse aggregate, 9 cubes of
size 15 cm × 15 cm × 15 cm .
 were cast for different percentage of demolished waste and for 10%-20%
waste glass for a mix have been cast in the lab. An effort has been made
here to compare the strength of cubes made up with different percentage
of demolished waste to the respective strength of conventional concrete at
the end of 7 and 28 d of moist curing.
 Sand replacement materials: waste glass that is crushed and screened is
a strong, safe and economical alternative to sand used in concrete.
 Cement: In this work, Ordinary Portland cement (OPC) of Ambuja(53
grade).

3. Continue..
 Fine aggregate: commercial sand is obtained from river beds or from
sand dunes originally formed by the action of winds.
 Coarse aggregate: Different types of glass of varying sizes and colors
were used instead of the 10mm to 20mm normal aggregate (NA) in
traditional concrete control mixer.
 Water: Potable water is used for mixing and curing, w/c of 0.33 has
been used.
 Concrete: The concrete mix design is M20.
 When use of Cement , Sand and Aggregate ratio is 1 : 1.5 : 3 and
water cement ratio is 0.33.
 Concrete may be produced as a dense mass which is practically
artificial rock and chemicals may be added to make it waterproof or it
can be made porous and highly permeable for such use as filter beds.

4. Comparison between Concrete & Glass
Cube
Concrete Glass Amery(For 10%)
 Sand = 2.280 kg Sand = 2.022 kg
 Cement = 1.500 kg Cement = 1.500 kg
 Aggregate = 4.500 kg Aggregate = 4.500 kg
 Water = 730 ml Water =730 ml
Amery = 228 gm
 TOTAL MATERIAL = 8.9 KG TOTAL MATERIAL = 8.9 KG

5. Comparison between Concrete & Glass
Cube
Glass Amery(For 20%)
Sand = 1.80 kg
Cement = 1.500 kg
Aggregate = 4.500 kg
Water = 730 ml
Amery = 450 gm
TOTAL MATERIAL = 8.9 KG

6. Replacement as a Percentage
Glass Amery(For 30%)
Sand = 1.57 kg
Cement = 1.500 kg
Aggregate = 4.500 kg
Water =730 ml
Amery = 675 gm
TOTAL MATERIAL = 8.9 KG

7. Advantages
 Glass is an ideal material for recycling. The use of recycled
glass saves lot of energy.
 Using waste glass in the concrete construction sector is
advantageous, as the production cost of concrete will go
down.
