BATCH 2
5
Water

• Activates cement through hydration reaction
• Increases workability of concrete

6
Cement

• Bonding Agent when activated by H20

7
Fine Aggregate

• Occupy most of the space in concrete and affect
  the strength of concrete

8
Z-Light Spheres Ceramic Microspheres

• Composition Silica-Alumina Ceramic
• Low-density, fine hollow particle size.
• Used to reduce the density of materials

9
3M Scotchlite Glass Bubbles

• In molded plastics, their high strength and
  spherical shape reduces warpage.
• Hollow glass microspheres
• Reduce part weight, lower costs and enhance
  product properties

10
Mixing Processes

• Obtain the materials Needed and their respective
  ratios.

11
Mixing Processes

• Properly combine the components and mix until
  obtaining the desired consistency.

12
Mixing Processes

• Once consistency is reached place concrete inside
  a form.

13
Mixing Processes

• Placing of concrete in forms must be done in 3
  sequences, each time thrusting the mixture 25x.

14
Testing Processes

• Samples must be cured for a minimum of 7 days.

15
Testing Processes

• After 7 days of curing the concrete is tested in
  an Universal Testing Machine.

16
Testing Processes

• Obtain values for compressive strength and peak
  loads

17
Testing Processes

• Test various samples to obtain a better and more
  accurate result

18
Conclusions

• Which mixture is better?
• Mixture 1
• or
• Mixture 2

19
Conclusions
20
Recommendations

• Possibility of using granulated plastic, glass,
  and fiberglass waste materials to partially
  substitute for the fine aggregate.

• Possibility of replacing some of the admixtures
  by Expandable Polystyrene and analyzing results.
