Improving the Jar Slake, Slake Index, and Slake Durability Tests for Shales
Environmental & Engineering Geoscience, 1998This study proposes modifications to three shale durability tests to improve reproducibility, reduce the level of effort required, and better correlate the test to actual slaking characteristics. Modifications to the jar slake test reduced test variability by one-third, offering a substantial improvement in consistency, with only a slight loss in the ...

Slaking and deformation behaviour
Géotechnique, 2016Slaking is a mechanical–hydraulic process in which geomaterials disintegrate or crumble when subjected to wetting and drying cycles; mudstone is particularly susceptible to this process. This paper explores the slaking behaviour of geomaterials derived from several kinds of mudstone and the mechanical consequences using a comprehensive set of ...

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1972
Abstract A test is described that measures the resistance of a rock sample to weakening and disintegration resulting from a standard cycle of drying and wetting. The main purpose of this ‘slake-durability test’ is to evaluate the weathering resistance of shales, mudstones, siltstones and other clay-bearing rocks.

SLAKING PROPERTIES OF SHALE ROCK IN THE IZUMI GROUP AND THE SLAKING MECHANISM
Doboku Gakkai Ronbunshu, 2003石のスレーキングは, 切土のり面の長期安定や盛土材として使用した場合の盛土の沈下問題を考えるうえなどで非常に重要な現象である. 和泉層群に広く分布する頁岩もスレーキングを起こしやすい岩石として知られている. しかし, スレーキングの特性や機構は十分には解明されていない. そこで, 頁岩のスレーキング特性を把握するために, 乾湿繰返し試験を, また, スレーキングメカニズム解明のため, X線回折試験. 電子顕微鏡写真撮影および水質分析を行った. その結果, 頁岩のスレーキング特性を明らかにし, また, メカニズムとしては, 長石・雲母の溶出および膠結物 (非結晶物質) の溶出であることが明らかにした.

Coke and Chemistry, 2012
A method of simultaneous coke cooling and classification is described. The method consists of two stages: (1) dry cooling from about 1000 to 650°C; (2) water-jet cooling in drums from 650 to around 200°C. At the same time, coke of size class
