Crack Width Gauge Card for Concrete

Crack Width Gauge Card for Concrete

Crack Width Gauge is for measuring width and length of cracks in concrete structures, pavements and other structural materials like plaster or drywall. Low cost alternative to a graduated microscope. Made of durable clear polycarbonate plastic and resistant to brief water exposure. One side has black marks for direct comparative measurement of cracks from 0.1 to 7mm (0.004 to 0.275in) wide, which is important for determining severity of cracks and assessing structural integrity to decide if repairs or maintenance is needed. The other side has clear 1mm graduations up to 165mm (6.5in) and is easy to use for width or length measurement of cracks even in tight corners. Compact size fits in a wallet for convenience during field inspections, ideal for on-site measurements. Available separately or as part of Crack Monitor Kits. Supplied with

What is a Crack Width Gauge Card?

A crack width card is a handy tool to measure the width of cracks in various building materials, concrete, masonry, drywall, stucco, glass and other structures. These cards are to provide a quick and easy way to determine the width of a crack, so inspectors and engineers can assess the severity of the damage and make informed decisions about repairs or maintenance, thus contributing to the overall structural health. Crack width cards also play a key role in identifying defects during inspections, supporting quality control and assurance by helping to detect workmanship issues early. Crack width cards are used with monitoring programs to track the width and length of cracks over time, to ensure the integrity of structures and other building materials.

What is Crack Width?

Crack Width is the width of cracks in concrete and other building materials. Designed for this purpose, it’s a quick and easy way to measure the width of a crack, which is critical to structural assessment and assessing the structural integrity of a structure. The gauge has graded lines or markings, with each line corresponding to a specific crack width, so you can measure by matching the crack to the nearest line. Engineers and contractors use crack width gauges to monitor buildings and structures. These gauges provide inspectors with a cost effective way to measure crack widths without the need for expensive equipment.

Features:

• Clear polycarbonate

• Marked in mm

• Markings on two long edges

• Can measure in tight areas

The gauge is compact and portable, about the size of a credit card so easy to carry and use in the field.

Technical Specifications

Crack width gauge cards have technical specifications that make them a must have for inspectors and engineers. These specifications may include:

• A specified width range, such as 0.004-0.100 inches (0.10-2.50mm)

• Graded lines or scales for precise measurement of crack widths

• Compact design, similar to a standard credit card

• Durable construction, often made from transparent or crystal-clear materials

• Unique serial number or QR code for tracking and verification purposes

The package includes: the crack card, protective carrying sleeve and user instructions.

Accuracy and Reliability

Concrete crack width gauges give accurate and reliable measurements of crack widths. Made from high quality like transparent plastic or thermoplastic, they ensure measurement precision every time. They are calibrated to specific standards like the American Concrete Institute (ACI) so the measurements are accurate and consistent. Many crack width gauges also have unique serial numbers for engineering traceability and measurement

Crack Width Gauge

Place over the crack, align the graded lines or markings with the edges of the crack to compare it to lines of similar width. This measurement tool will give you measurement of crack widths in concrete.

Best Practices

To get accurate measurements and reliable results, follow best practices when using a card. Here are some tips:

• Handle with care to avoid damaging the lines or scales

• Make sure the card is clean and free of debris before use

• Place the card over, align the lines with the crack width

• Read off the width value from the card, note the width range

• Use with a monitoring program to track changes in crack width over time

• Consider a low-cost alternative to graduated microscopes or other measuring devices

• Look for durable construction and compact design for field use

By following these tips and using a card, engineers can get accurate and reliable measurements of crack widths and gain valuable insights into the condition of structures.

Industries and Applications

Concrete crack gauges are used in construction, engineering and inspection. They are used in structural monitoring to track changes in crack widths and identify potential problems before they become major issues. Concrete crack width gauges are used in quality control and assurance programs to ensure materials meet specific standards and specifications. They are also used in research and development to advance our knowledge of concrete behavior.
