Hi, good job here. Does the steel frame thermal expansion effect the rammed earth enclosing it at all? Is there any cracking observed on the face of the Rammed Earth panels due to difference in materials? Since the project is 2 years old now should be suitable sample size to determine the effects if any.
This not rammed earth! This is just dirty concrete!!! You need probably double the amount of cement than in a nomol concrete wall! How can that be better for the environment??
Hi Johannes, Precast concrete uses upwards of 20% cement, washed sand (a high-embodied energy material) and crushed rock (ditto). It requires substantial infrastructure including delivery trucks of the raw materials to the batching plant, the actual batching plant, delivery of the concrete to the precast site in massive mobile barrel mixers and often concrete pumps which need to be driven to and from the site. In contrast, the rammed earth we used, uses 7% cement and locally sourced hill granite (from a quarry 8km away from the depot). The rammed earth is built with a fraction of the infrastructure of a concrete batching plant, uses minimal fuel (25 litres per day for the bobcat and air compressor) and has no reinforcing steel unlike concrete.
@@kapitolgroup Thank you for the answer. It is still not rammed earth! Rammed earth contains 0% cement! This is called stabilized rammed earth period. With 7% cement you lose the best properties of clay, indoor climate regulation, moisture absorption, reusability, etc......! Please give it the right name. Rammed earth is misleading for what you are doing. Best regards
What is the base made of? Is sit on a concrete?
is it possible to get the construction details of the columns, please.
drawings might as well help

Good job 👍👍👍
Thank you.
What type and make of formwork did you use?
Hi Peter, we used Peri Duo Panels.
👍🏾👍🏾
