The sand and cement should be thoroughly mixed dry. The mixing should be done on some non-absorbing surface, preferably plate glass. If the mixing must be done on an absorbing surface it should be thoroughly dampened prior to use. Bulletin - Page 377by Ohio. Division of Geological Survey - 1904Full view - About this book
