[ Experiment 5.06] How to make a super sand pile ?
Science experiment #5.05 "How is good sand paste made?" ( • Comment faire un bon p... ) shows that in order for a sand block to withstand a heavy load, it is necessary to compact thin layers of sand one after the other: the resulting pile is six times stronger than a sand pile compacted at one time. This is exactly the logic of the rammed earth technique: the thinner the layers of earth that are compacted, the more compact and resistant the material. But is it possible to increase its strength?
This video shows that by adding reinforcement during the creation of the sand pile, it is able to support the weight of a man. Through traction, the armature restrains the horizontal push of the grains, greatly increasing the resistance of the sand pile and thus preventing it from collapsing.

C'est le rôle de la paille dans les enduits à la terre je suppose?
