Hi Noom,
Sawa dee ka :>
Another brick test (see attached). It breaks into 3 pieces but all 3 parts feels really strong. For this brick, the ration soil : cement was 7 : 1.5. Is this test good?
The ratio for the previous brick was 7 : 1.
The cement we used was the cheapest we can find - composite cement.
1 more question:
What do you do to those bricks which are spoiled? Do you put them back to the ground? We are wondering what to do cos there are cement content in them & don't really wanted to 'contaminate' the soil.
Hear from you soon....
Regards,
