We are currently building a bamboo framed community building in Northern Thailand and have the sane questions about this topic. We are experimenting using split bamboo verticals ( 5 cm. wide with 5cm. wide horizontal lathing at 5 cm spacing) and are wanting to fill the void with a clay and corn cob slip mix along with a rice straw to bind the matrix. We have been using a borate solution to treat the bamboos for powder post beetle and termite and will do the same with the cob. The local temple has started a clay/ cement brick making business to offset the new temple building cost and have as part of their equipment a very large clay and concrete mixing vat that we are hoping to rent for mixing the clay/ cob in large quantities for group usage . The rice and corn harvest is about two months away and I will be happy to keep you posted with the project.
The walls on the building e not load bearing and are mostly for insulation so we are not concerned the structural capacity . Good luck with your projects........
