2. What is Mortar?

3. Rapid Setting Mortar Significance
Move at quicker rate
Less time on the job
Reduced job cost

4. Colloidal Silica
* Nano-silica particles that have been pre-suspended in liquid * Effects on mortar: improve flowability, decrease set-time, and increase compressive strength.

5. Objective- Test effects of Colloidal Silica
Design mortar mix.
Create different samples.
Test each mix.
Compare results.

6. Mortar Design
Using Electric Mixer

7. Without ------------------- With
Different Mixes
Control Mix- Basic Mortar Mix
3 MIXES- Different percentages of Cembinder 8 and Cembinder 30
Without With

8. Testing our Designed Mixes
Vicat Needle Test
Flow Table
Compression Test

9. Compare Results (of each mix)
Compression test- 1, 7, 28 days aged.
Vicat Needle & Flow Table test- day mixed
Compare results of all tests to control mix.

10. Timeline Time Activity Assigned Person February
