Here is how you can easily test the clay contents of sand:1. Fill a bottle half full with river sand.2. Add water until the bottle is nearly full.3. Close the lid of the bottle.4. Shake the bottle well.5. Let the bottle stand until the river sand settled and the water at the top is clear. (+- 1 hour)6. If you do not see a clear separation between the layers of sand, repeat steps 4 and 5.7. Look at the different layers of sand.

Bottom Layer: rough sand


TRIAL AND ERROR

Try different ratios of river sand and water to Ohorongo Cement to obtain optimal brick strength.• Always use the same size bucket to measure all the components.• Always fill buckets in equal measures (level the bucket with a trowel)

1. Start with: 4 buckets of river sand to 1 bucket of Ohorongo Cement and produce a few bricks.

2. Change the ratio to: 5 buckets of river sand to 1 bucket of Ohorongo Cement and produce a few bricks.

3. Change the ratio to: 6 buckets of river sand to 1 bucket of Ohorongo Cement and produce a few bricks.

After letting the bricks cure for 7 days, test the

strength of the bricks (See page 17)

Ohorongo Cement and clean water

equals Very strong brick

(cement paste) Very expensive

• Make a heap with the mixed river sand and Ohorongo cement.

• Make a hole in the middle.

• Carefully pour measured water into the hole and start mixing the water and the cement-mix, from the outside inwards. • If necessary, add more water/sand in small quantities until you have a semi-dry to moist concrete mixture that has a uniform colour. Remember:

• The dryer the mix, the stronger the brick.

• The wetter the mix, the weaker the brick.You should not mix more concrete than you can process in 1.5 hours, because the concrete starts hardening and does not bond/glue that well anymore.

This means your brick is going to be weak and will break.
