Hydraulic limestones, sometimes referred to as argillaceous limestones have a high proportion of clay and silicia (15-20 %) and can be either high calcium or magnesian.
These siliceous sand-rocks are either held together by a siliceous cement, or have a greater or less portion of clay in them, which in some acts as a cement to the siliceous crystals, but in others is in such great abundance that in burning them they become an imperfect porcelain and are then used to repair the roads, as at Chesterfield in Derbyshire; these are called argillaceous grit by Mr. Kirwan.
Besides metallic bolts, wooden slot-and-wedge anchors were applied in the U.S.A. mainly in places with soft hanging such as argillaceous and quarzitic shalestone.
