Application of SFRC in Critical Members

Although Steel Fibre Reinforced Concrete (SFRC) has a history in academia of over 50 years, its adoption in practice has mainly been limited to non-critical elements. In order for SFRC to be used on a regular basis, a rational framework of material models identifying the key material constitutive parameters must be established... More Info

Steel Fibres: Design, Quality and Performance

The concept of using fibres as reinforcement is not new. Fibres have been used as reinforcement since ancient times. Historically, horsehair was used in mortar and straw in mud bricks. With the recent adoption of Steel Fibres into the AS5100.5 Bridge Code, the need to better understand the application of Steel Fibres in concrete has come to the fore. More Info

Design Challenges for Piles to Support Tall Buildings

The last two decades have seen a remarkable increase in construction of tall buildings in excess of 150m in height, and an almost exponential rate of growth. A significant number of these buildings have been constructed in the Middle East and Asia, and many more are either planned or already under construction. “Super-tall” buildings in excess of 500m in height are presenting new challenges to engineers, particularly in relation to structural design 

This webinar reviews some of the challenges that face designers of foundations for very tall buildings, primarily from a geotechnical viewpoint. More Info

Concrete Variability

Raw materials are dug from the ground and are intrinsically variable. For example,  limestone from one end of the quarry might well contain more clay or silica than limestone from the other end.

Fuels are variable - coal varies in ash and sulfur contents and these days, a works may also burn ancillary fuels such as solvents or car tyres.

Variation in raw materials and fuels are likely to result in changes in kiln conditions and consequently, to some extent at least, to changes in the concrete. Of course, some changes may be for the better, but unless they are maintained consistently, the result will be variability in the production opf concrete. More Info

Legal Issues in Construction

Recent bridges failures and the evolution of bridge engineering - some insights - The bridge engineer

Structural integrity is the ability of an item—either a structural component or a structure consisting of many components—to hold together under a load, including its own weight, without breaking or deforming excessively. It assures that the construction will perform its designed function during reasonable use, for as long as its intended life span. So why do we experience catastrophic bridge collapses.

Back to Basics - Pumping Concrete

We take the equipment for granted too often because normally when everything is going well our level of confidence is high. We find ourselves “in the groove“ and we do our jobs and make it look easy to observers. What separates the best ops from the average is how the sudden, unexpected interruption of their ‘rhythm’ is handled. These interruptions can often take place in milliseconds and how quickly and appropriately the operator reacts can mean the difference between a successful outcome with a signed invoice, or a failed pour.

Concrete Cracking and Crack Injection

Cracks in a concrete structure can cause the ingress of water, decreased structural integrity, and can lead to further degradation of a structure over time. Cracks have resulted in wet basement walls or flooded basements, most concrete construction jobs require some remedial action to fix cracks in concrete.

Watertight Concrete Structures

In reality, there are many applications of concrete in which permeability plays an important part in concrete performance. Virtually every home or building basement is in need of watertight concrete. In fact, concrete must be impermeable for nearly every below ground application. More Info

Achieving a watertight concrete structure

To achieve watertight concrete structures that are suitable for the service conditions, it requires the synthesis of appropriate material selection and mix design, adequate structural design, detailing and high standards of construction techniques and practices. All of these aspects must be adequately dealt with simultaneously to achieve a watertight structure. More Info

Watertight engineering solutions

Ideally water will seep away quickly and immediately without building up pressure against a concrete structure, however; the reality is that water builds up pressure along the deep foundations and the basement of a structure and results in water damage.
