Factors Influencing Anchor Profile

Factors Influencing Anchor Profile
Available for download

Anchor profile achieved during field blast cleaning operations is often found to be deeper than expected, even when available information suggests the size of the abrasive selected was appropriate. Three parameters long identified as influencing anchor profile depth were evaluated under laboratory conditions.

Anchor profile achieved during field blast cleaning operations is often found to be deeper than expected, even when available information suggests the size of the abrasive selected was appropriate. Three parameters long identified as influencing anchor profile depth were evaluated under laboratory conditions. This paper discusses the results obtained by changing blast nozzle pressure, angle of attack (incidence) and stand-off distance on the anchor profile achieved when blast cleaning with steel grit. Anchor profiles obtained from preliminary field data are also briefly described.

Factors Determining the Size of Projects

Product Number: 41207-304-SG
Author: Ralph Baliunas, Louis G. Lyras
Publication Date: 2007
$20.00

This paper identifies the problems with large multi-year painting projects and discusses the benefit to Facility Owners and Contractors for breaking a large bridge project into smaller phases. It will also discuss factors that determine the optimum size, large or small, of a painting project and their impacts. The size of a project will be analyzed from the standpoint of money, time, insurance, bonding, manpower, inspection, management, bridge inventory and job quality.

Extending the Function of Concrete as a Cladding Material

Product Number: 41207-299-SG
Author: Lorella Angelini
Publication Date: 2007
$20.00

“Tilt-up" is a state-of-the-art building system in which steel reinforced concrete panels are cast on site and tilted up into their final position. The tilt-up panels are load bearing and also function as cladding elements. With the exceptions of integrally colored concrete, tilt-up concrete panels can look bare and unattractive if a finish is not applied. It is also well known that concrete is not a “perfect” material as it shows porosity and micro-cracks which can lead to deterioration over time.

Evaluation of Resistance to Cracking of Concrete Repair Materials

Product Number: 41207-300-SG
Author: Frank Apicella, Fred Goodwin
Publication Date: 2007
$20.00

Cracking of concrete repair materials is a critical factor affecting the service life of a repaired structure. Cracks in repair materials provide a pathway for moisture to carry deleterious materials into the concrete and accelerate corrosion of imbedded reinforcement. Existing cracks can also fill with water and cause further crack propagation as well as accelerated deterioration due to freezing and thawing conditions.
