On the high stress compression of bentonites
WebThe compressive strength of the material corresponds to the stress at the red point shown on the curve. In a compression test, there is a linear region where the material follows Hooke's law.Hence, for this region, =, where, this time, E refers to the Young's modulus for compression. In this region, the material deforms elastically and returns to its original … Web5 de jun. de 2024 · A bentonite’s ‘yield value’ is the number of barrels (1 US oil barrel = 158.987 litres) of bentonite slurry with a specific viscosity (15cps) yielded when one ton (2,000 lb/907.1847 kg) is ...
