Building Materials

In a muddy, silty delta such as Bangladesh, gravel is hard to come by. Bricks are hand made in kilns under excruciating conditions, and then some are broken into gravel. Of all the job I would never want to have, brick breaker is high on the list. People actually sit on piles of bricks all day with little hammers, or rocks, breaking bricks into gravel. I did see a brickcrusher once, which looked like a woodchipper. We just need more of those.
