When the Cube Fails: What to do when strengths appear not to be as specified
Venue: Online
The strength of concrete is primarily measured by the testing of cubes made from the fresh concrete supply. On occasion lower than expected test results may be received, casting doubt over the quality of the concrete in a structure. While many factors may disrupt construction schedules, few are more frustrating than questions concerning concrete quality. Therefore, the causes of these failures need to be identified in order for the correct course of action to be taken.
Delivered by highly experienced industry professionals, this seminar will explain the differences between cube strength and in-situ concrete strength, together with the course of action in the event of cube failure. In addition, the seminar will advise on how results should be interpreted, and the consequences to all parties of poor practices.
This seminar will provide crucial information for Design Engineers, Site Engineers, those in supervisory roles and all who are interested in the efficient delivery of quality concrete structures. Ready-mixed concrete producers and client representatives will also benefit from attending.

Second Life: options for repair and refurbishment of structural concrete
Venue: Clayton Hotel Liffey Valley, Dublin
Concrete structures are designed to last for at least fifty years and often beyond. Efforts are increasingly turning towards improving the durability traits of concrete to ensure even longer lasting structures. This longer-term view is also being applied to existing buildings and structures whereby refurbishment and repair contributes to the extension of expected service life. This can result in increasing the sustainability of building resources through the reuse and adaptation of concrete buildings to meet future needs, and infrastructure that continues to meet its operating requirements beyond the original intention.
In this seminar our experienced panel of speakers will provide practical information and guidance on issues to be considered, their assessment and options available for repairing concrete structures.
This seminar has been designed for all those in mid to senior level positions. Design Engineers, Local Authority Engineers, Resident Engineers, Main and Specialist Sub-Contractors will all find this seminar very beneficial. Asset Managers and Clients will also benefit from attending.

Practical Concreting
Venue: Online Event
Advances in constituent materials, production processes, and construction technologies have all contributed to improvements in concrete construction. However, the successful execution of concrete construction requires sound practice on site. Careful planning of on-site resources and processes, together with coordination and communication, are necessary to minimise potential problems, and to ensure quality is achieved and maintained throughout.
In this short course, our experienced panel of speakers will provide practical information and guidance for those involved in the planning, management and supervision of concrete construction work.
This course has been designed for all those in mid to senior level positions. Contracts managers, project managers and site engineers will all find this course very beneficial. Site supervisory personnel, consulting engineers, ready-mixed concrete producers, and client representatives will also benefit from attending.

Summer Concreting
Venue: Online Event
Hot weather conditions are usually caused by a combination of factors including high ambient temperature, high solar radiation, low relative humidity and high wind velocity. While prolonged high ambient temperatures are not common in Ireland, ambient temperatures of 20°C and above, together with low humidity and drying winds present a high risk to long term concrete quality.
As these conditions can impact both fresh and hardened concrete, precautions are necessary to ensure that concrete performance is not unduly affected. In this seminar we will provide practical information for the successful planning and placing of concrete during the summer months.
This seminar will be of intertest to Main Contractors, Consulting Engineers, Local Authority Engineers, Specialist Sub-Contractors, Site Supervisory Personnel and Producers.

Advanced Concrete Technology Lecture: Calcined Clay as a Secondary Cementitious Material
Introduction
The fastest route to reduce CO2 emissions from cement and concrete is either to replace the clinker in cement, or cement in concrete, with a supplementary cementitious material (SCM). The SCM which is sufficiently abundant to serve the industry world-wide is clay. This talk goes through all aspects of calcined clay as an SCM; what it is, how it is produced, how does it react with cement as well as what the benefits are when using it in concrete in terms of strength development and durability. The challenges and potential benefits of extremely high calcined clay loadings are also addressed.
Who should attend
This free to attend lecture will be of interest to all those who are involved in the design, specification, production and construction of concrete. Those who should attend include ready-mixed and precast concrete producers, concrete technologists, cement producers, design engineers, consulting engineers and engineers in contracting and sub-contracting firms.
Speaker Biography
Prof, Dr Harald Justnes is Chief Scientist at SINTEF Community, Department of Architecture, Building Materials and Structures, Norway. He is also Adjunct Professor in “Cement and Concrete Chemistry” at Institute of Materials Technology, Norwegian University of Science and Technology.

Cold Weather Concreting
The negative effects of placing concrete in cold weather are well established. Concrete can be damaged to such an extent that it is unfit for use, has lower strength development or reduced durability. Therefore, it is important that precautions are taken to ensure that the performance of the Concrete is not unduly affected.
In this seminar we will deal with the practical aspects of successfully placing concrete during cold weather. We will also look at the damage caused by freezing temperatures to fresh concrete.

Floor Screeds: An essential update for professionals
Venue: Online Event
Screeds can often be viewed as non-structural, straightforward elements which do not require consideration, leading to avoidable problems.
There are a variety of screed materials now available that require very specific types of installation. A lack of knowledge by professionals can lead to issues such as: screeds being specified that are not adequate for the intended use, inappropriate or inadequate installation, or systems that cannot be installed in the required time.
Delivered by experienced industry professionals, this seminar provides guidance on important design and specification considerations, in addition to installation best practice, and finishes.
This seminar is an essential update for all those who design, specify, install or supply quality floors in Ireland.
Fee: ICS Member: €60, Non-member: €90
