Hydraulic cement is a type of cement that sets and hardens when mixed with water. It is used in many construction and repair projects, from fixing cracks in sidewalks to lining the bottom of ponds. It usually consists of a fine powder made from limestone, clay or gypsum. When mixed with water, the powder forms a paste that can be spread or ...
Mortar mix is another alternative that can be used on cement boards. Similar to thinset, mortar mix is applied to the cement board with a trowel and then smoothed out. This creates a rough surface that is ideal for the application of tile or other finishes. 3. Epoxy. Epoxy is a strong adhesive that can be used on cement boards.
Overview. Vertebroplasty is a treatment that injects cement into a cracked or broken spinal bone to help relieve pain. Spinal bones are called vertebrae. Vertebroplasty is used most often to treat a type of injury called a compression fracture. These injuries are usually caused by osteoporosis, a condition that weakens bone.
