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 ...

Soils and Foundations, 2019 Abstract An earthquake in Suruga Bay off Shizuoka Prefecture in 2009 caused an embankment near the Makinohara Service Area of the Tomei Expressway to fail. One of the causes of this failure was the slaking progression of the Neogene Period mudstone in the lower portion of the embankment. The objective of this study is to understand how the degree of

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.

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 ...

Hydrometallurgy, 1990
Although the slaking of lime is a reaction of great antiquity, there have been few fundamental studies of its kinetics and mechanism. In this paper, the kinetics of the reaction are reported for lime samples in two different arrangements: rotating discs and powders.

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.

Mechanics of the slaking of shales
Geomechanics and Engineering, 2011Waste fills resulting from coal mining should consist of large, free-draining sedimentary rocks fragments. The successful performance of these fills is related to the strength and durability of the individual rock fragments. When fills are made of shale fragments, some fragments will be durable and some will degrade into soil particles resulting from ...

The Effect of Lime Slaking Conditions on Slaked Lime Quality
2006Yapılan çalışma ile söndürme şartları ve farklı su yüzdelerinde söndürülerek üretilen kireçlerin özellikleri arasındaki ilişki incelenmiştir. Laboratuar şartlarında 1000 °C’de kalsine edilmiş söndürülmemiş kireçlerin (CaO) ve ağırlıkça farklı su yüzdelerine sahip söndürülmüş kireçlerin (Ca(OH)2) özellikleri (porozite, özgül yüzey alanı, %aktif CaO, %Ca(
