KTA University “Test Your Knowledge” Series – Surface Profile Measurement
Introduction/Background Surface profile is defined as a measurement of the maximum peak-to-valley depth created by abrasive impingement against a surface during abrasive blast cleaning operations, or by an impact-type power tool. During abrasive blast cleaning, the mass of the abrasive and the velocity of the abrasive movement created by compressed air generates kinetic energy (the…

Inspection of the Precast Concrete Surface Preparation and Coatin
Introduction – Precast concrete is cleaned and painted for both beautification and protection. Painting may involve the use of protective coatings, stains, or water repellents. For the materials to adhere and provide t...
Coating Systems for Precast Concrete
Introduction – When it is time to decide if precast or other concrete elements should be protected with a coating layer, consideration must be given to the reasons for coating it (protection and/or aesthetics), the type of structu...
Preparation of Precast Concrete for Painting
Introduction – Precast Concrete refers to concrete that is poured (cast) into a form (mold) at a manufacturing facility and allowed to cure under controlled conditions. A release agent is applied to the form prio...
Inspection of the Precast/Prestressed Concrete Fabrication Proces
Introduction – Inspections are an essential part of the precast concrete production process. Items such as sound walls, traffic barriers, and retaining walls are a few types of precast concrete products. Precast concrete dif...
