The concrete floor is cut with a variety of diamond abrasives of the concrete slab. Polishing can be done wet or dry. However, in the United States, new OSHA regulations on crystalline silica and protecting skilled trades in the concrete, masonry, and brick industries are encouraging the development of wet refinement systems or the use of ...
A concrete grinder is an abrasive machine for grinding and polishing concrete and natural stone. Concrete grinders can come in many configurations, the most common being a hand-held general purpose angle grinder, but it may be a specialized tool for countertops or floors. Angle grinders are small and mobile, and allow one to work on harder to ...
Diamond grinding is a pavement preservation technique that corrects a variety of surface imperfections on both concrete and asphalt concrete pavements. Most often utilized on concrete pavement, diamond grinding is typically performed in conjunction with other concrete pavement preservation (CPP) techniques such as road slab stabilization, full- and partial-depth repair, dowel bar retrofit ...
Bonded terrazzo is applied over a sand-cement mortar underbed which sits on top of a concrete slab. The sand-cement layer allows for variations in the finished concrete slab that it sits on. Monolithic terrazzo is applied directly over an extremely flat and high quality concrete sub-floor. Thin-set terrazzo does not require a concrete sub-floor.
Thinset (also called thinset mortar, thinset cement, dryset mortar, or drybond mortar) is an adhesive mortar made of cement, fine sand and a water-retaining agent such as an alkyl derivative of cellulose. [1] It is usually used to attach tile or stone to surfaces such as cement or concrete. [2]
Slots are cut using diamond-tipped saw blades; the existing concrete is removed and the dowels are placed in the slots across the joints or cracks. The slots are then backfilled with a non-shrink grout and the pavement is diamond ground to restore smoothness. The diamond grinding removes excess grout and any displacement of panels.
In modern construction, scabbling is a mechanical process of removing a thin layer of concrete from a structure, typically achieved by compressed air powered machines. A typical scabbling machine uses several heads, each with several carbide or steel tips that peck at the concrete. It operates by pounding a number of tipped rods down onto the ...
A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel- reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving ( see below ).
