Surface protection of concrete structural members is necessary to protect the structure from damage due to environmental considerations. Corrosion of reinforcement due to permeability of water / moisture, chemical attack on structural members, structures nearby sea-coast etc. are all responsible for damage to concrete structures. So, surface protection of concrete members becomes necessary to ...

This industry comprises establishments primarily engaged in (1) erecting and assembling structural parts made from steel or precast concrete (e.g., steel beams, structural steel components, and similar products of precast concrete) and/or (2) assembling and installing other steel construction products (e.g., steel rods, bars, rebar, mesh, and cages) to reinforce poured-in-place concrete.

Diamond grinding is a concrete pavement restoration technique that corrects irregularities such as faulting and roughness on concrete pavements. Diamond grinding should be used in conjunction with other Concrete Pavement Rehabilitation (CPR) techniques. A full CPR job can restore structural and functional capacity of a pavement to acceptable levels for a specific traffic need. Full-depth ...

Construction and engineering firms use concrete test cylinders for quality control purposes – to ensure that concrete cures properly, that structures can support desired loads, and that different batches of concrete uniformly meet design strength standards. A variety of machines and tools are used for cylinder testing and end grinding, as well as the storage and monitoring of cylinder ...

Grinding removes material using fixed abrasive particles that produce chips of the specimen material (see below). The process of making chips with a sharp abrasive grain produces the lowest amount of deformation in the specimen, while providing the highest removal rate. The three positions of an abrasive grain passing the specimen surface in a fixed state are: Position 3: The grain passes out ...
