These common rock mixtures, known as bimrocks (block-in-matrix-rocks) or bimsoils (when the matrix material is soil-like) are very difficult to evaluate.
The applicability of these methods to model thermal-hydraulic processes within the bentonite/crushed rock mixtures in a deep repository needs to be assessed.
The permeability and thermal conductivity of bentonite/crushed rock mixtures used as backfill for a nuclear waste repository have an important impact on the maximum radioactive load of the waste canister that can be embedded.
Our research pursues useful methods for estimating the permeability, thermal conductivity, and specific heat of various bentonite/crushed rock mixtures for the conditions expected to prevail at the Äspö Hard Rock Laboratory (ÄSPÖ HRL).
The temperature difference between the center and the surface induces an intensive convection of water-rock mixture which flattens the temperature distribution.
Walls were made of tamped earth sandwiched between wooden boards, adobe bricks, a brick and stone mixture, rocks, or pilings and planks.
Fluid contents and salinity are obtained by comparing model conductivities of fluid-rock mixtures with observed values in the forearc mantle (Fig. 2).
The discovery is more like damp rock: a mixture of 1% ice and 99% regolith, spread over thousands of square kilometres at the poles.
