Blog

PCTE's blog about the world of NDT, first released in August 2011 in this format we are extremely proud of the articles and information that we have produced internally and those that have been shared by our partners, suppliers and customers.

A Brief Guide About Concrete Testing Equipment

When choosing concrete testing equipment, the selection includes in-situ and lab-based instruments. Concrete testing in Australian laboratories is focused on testing the compression strength of cylindrical samples. Using the right equipment.

Know About Geotechnical Tools and Equipment

Geotechnical engineering is focused on the behaviour of natural materials like sand, soils, and aggregates in relation to a structure.

A Brief Guide About Schmidt Hammer

Non-destructive concrete testing methods are more favoured as they provide quicker and more reliable results, while helping operators save time and money. 

Uses of Concrete Resistivity Meter

Resistivity is one of the factors that can determine the presence of corrosion and its rate of progression in concrete. When corrosion occurs, ions flow between cathodic and anodic sites on reinforcement, while resistivity controls that flow’s rate.

GPR and Post Tensioning Scanning 

Ground Penetrating radar is the right tool to locate post tension tendons inside a structure, but operators need to be aware of the differences from regular scanning. 

Coating Thicknesses on Concrete Using Positector 200 Gauge

Coating thicknesses on concrete are straightforward to measure, but it is important to understand the tools and how they work.

Congratulations Reuben!

Our head honcho Reuben recently attended the Concrete Institute of Australia's WA Branch Seminar, read more about it...

An Introduction to Ground Penetrating Radar

We introduce Ground Penetrating Radar.

How to Cure Concrete and Developments in GPR

This blog post discusses concrete curing in Australia and looks at a case study on the developments in GPR software.

How to Locate Defects in Concrete

We look at the non-destructive testing methods that can be used to locate defects in concrete as well as some of the basic methods for processing GPR data.

Benefits of the Cover Meter System in Pre-Cast Yards

The first blog post for 2017 discusses the Defelsko Positector range along with the benefits of cover meter system in pre-cast yards. 

The Benefits of the LMX-200 GPR

This blog is discussing the use of the LMX-200 GPR with GPS data and Google maps and presenting a case study on structural monitoring using vibrating wire crack meters. 

Standards of Non-Destructive Testing Equipment

We look at confirming testing equipment meets a standard and a detailed case study of meeting the ASTM F2170 standard for humidity testing of concrete.

Corrosion Monitoring and Light Weight Deflectometers

To support corrosion investigation works one of our articles this month talks about tools for corrosion monitoring. We also discuss the benefits of Light Weight Deflectometers in evaluating pavement systems.

Analysis of Raw Data from GPR and a Cover Meter

In our final blog post for the year we are looking at raw data from two systems, GPR systems for utility location and the raw magnetic measurements from a cover meter. 

How to Monitor Temperature of Bulk Concrete Pours and the Silver Schmidt Hammer

We have two topics for this issue: one for temperature monitoring of bulk concrete pours and the other focusing on the Silver Schmidt Hammer and converting its Q value results to R values common to older correlation curves built using an Original Schmidt.

Technical Overview of Compression Machines and How to Locate Post Tensioning With GPR Systems

Our articles this month are a technical overview of compression machines and force measurement and a case study on locating post tensioning with GPR systems.

How tdo a Concrete Cover Check

As more and more quality assurance specifications require concrete cover checks nowadays, we will give you a comprehensive overview of how to carry them out properly. We will also present an extract from our Australasian Tunnelling Society conference paper on geotechnical instrumentation of tunnels.

What is Impact Echo Testing and I Dumitru’s Paper Results

We discuss the finer points of impact echo testing for shallow foundations, along with a summary of the results of I Dumitru's paper on the effects that grinding cylinder ends before compressive testing compare with results from cylinders that are sulphur or rubber capped.

Focusing on Ultrasonic

Ultrasonics is the focus for this blog post, looking at ultrasonic pulse echo data processing, along with the regular sound wave sister to ultrasonic pulse velocity, sonic pulse velocity testing.

Investigating Corrosion Monitoring and Half-Cell Potential

Once again this issue overlaps with the Australian Corrosion Association's conference. Discussed topics include Corrosion Monitoring and Half-cell potential investigations. 

Structural Health Monitoring and Geotechnical Testing

Structural Health Monitoring and Geotechnical Testing take centre stage in this post. There is also a vibrating wire sensors case study. 

Tips and Hints for Completing a Successful Testing Job and How to Measure Concrete Thickness

With a new year, our blog went back to basics, discussing hints and tips for successful completing of any testing job, the role of standards and an in-depth analysis of different testing methods that can be used for concrete thickness measurements. 

Resistance and Resistivity

This blog post overlaps with the Australasian Corrosion Association’s annual conference, it features a revised article on Resistance and Resistivity and some information on state of the art ground penetrating radar technologies for corrosion investigation

Pile and Foundation Tests

In our first issue for 2012 we focus on pile and foundation tests, with a fantastic case study and technical overview of Sonic Echo/Impulse Response testing and quick overview of the other tests that can be applied to this broad area of testing.

All Things Corrosion

This blog post in 2011 lined up with 18th International Corrosion Congress and to celebrate we focused upon all things corrosion. We talk about corrosion monitoring and investigation and look in detail at Concrete Resistivity as a quality assurance tool.

How to use the Reb-Ultra method of Testing

In this issue we look at strength testing using the Reb-Ultra method which combines ultrasonic testing and rebound hammer testing. Secondly, we look at the challenges of locating footing and some of the equipment that can be used to assist the hunt.
