Revision history [back]
Using earth mortar use for reconstruction in earthquake prone areas
Construction of housing: single storey stone buildings with earth mortar
For very poor families with almost no resources rebuilding their own houses what would be the most effective way to make reconstruction safer? Safety here is defined as minimising damage from small earthquakes and maximising escape time for inhabitants in large earthquakes.
Sub questions
- It has been suggested that a small percentage of cement mixed in with the earth mortar would achieve this, but other advice suggests cement is only effective in sand based earth mortar, and ineffective in clay based mortar:
(a) Is it true that cement is only effective in sand based earth mortar, and ineffective in clay based mortar?
(b) Would a small percentage of cement have the desired effect of increased safety?
2. It has been suggested that reinforcing the mortar with fibres (rope, hemp etc) would be effective to increase safety (without cement). Is there any evidence to support this?
