School of Concrete Technology

Welcome to the School of Concrete Technology (SCT)

We live in exciting times! Especially in the field of concrete technology.

These exciting times are being brought about by climate change and new technologies.

Climate change is now a reality, revealing itself with the ever-increasing occurrences of extreme weather events, rising sea levels, loss of ice cover in the arctic and northern hemisphere, warming oceans, rising temperatures, and changing rainfall patterns. Extreme weather events such as flooding, storm surges, high winds, heat waves and droughts with frequent and severe wildfires, requires a resilient and pro-actively designed and built infrastructure. Concrete will play a vital role in the mitigation of these adverse effects.

Climate change unfortunately presents a double edge sword for the concrete industry. Durable concrete infrastructure is needed for the mitigation of extreme climate change events while at the same time there is an associated carbon footprint with the use of more concrete. Herein lies a second exciting challenge for concrete technology, which is the drive towards carbon neutral concrete.

Striving for a lower concrete carbon footprint involves interesting challenges in mix design, material use and structural design covering the whole life cycle of concrete. Something that, only a few years ago, truly little time and thought was assigned to.

New technologies are evolving in the concrete industry. The deployment of drone technology, thermal imaging, remote sensing, admixture advances are all examples, but by far the newest and biggest kid on the block is 3D concrete printing. It is in its infancy and currently can be likened to the ‘brick like’ cell phones of yesteryear, but given the phenomenal advances in cell phones, we can easily say, regarding 3D concrete printing, in words borrowed from Bachman-Turner Overdrive “You ain’t seen nothin’ yet!”. The potential for 3D concrete printing is quite staggering, providing juicy work for those involved in concrete technology and structural design. The concrete ‘ink’ mix design requires a whole new innovative look at materials and  admixtures to meet the unique properties required of 3D printed concrete.

To take advantage of these ‘exciting times’ a solid foundation in concrete technology education is needed. The School of Concrete Technology (SCT) has a structured progression of course levels that will allow a prospective student to join at a level that matches his or her competency. There can be no short cuts to becoming a good concrete technology practitioner and the SCT has all the educational requirements to help you meet your goals.

Please contact the School of Concrete Technology to discuss the best concrete technology educational path for you.

The school would like to thank all clients and students that supported us during 2023. We look forward to continuing your concrete education in 2024.

e-learning self study
Concrete technology & construction (Stage 2 and 3) offered by the Institute of Concrete Technology (ICT) based in London

The SCT 41 and 42 are ideal bridging courses for those who would like to do the SCT 50 Advanced Concrete Technology diploma. They will substantially expand on the knowledge gained in the SCT 30 Concrete Technology course. It is recommended that a potential delegate should have completed the SCT 30 Concrete Technology course before attempting these courses. A pass in the SCT 41 and 42 courses is a prerequisite to being accepted onto the SCT 50 Advanced Concrete Technology diploma program.

The two courses offered are:
SCT 41: General Principles (Part 1) (ICT Stage 2)
SCT 42: Practical Applications (Part 2) (ICT Stage 3)

The courses are presented in an e-learning – self study format. The aim in studying concrete technology via these on-line course will be to prepare yourself for the Institute of Concrete Technology’s Stage 2 and Stage 3 (General Principles & Practical Application examinations).

The Institute of Concrete Technology (ICT), based in London, UK provides the course objectives and the final examination.

Cement & Concrete SA (CCSA) based in Midrand, South Africa provides you with:
• The on-line course, consisting of 36 online lessons covering all the ICT requirements
• Specialist lecturer supervision, guidance and input, via email
• Online compulsory workshops are scheduled shortly before the examination
• An examination venue
• A compilation of ICT past years exam papers
• Upon registration and full payment, you will receive a licence key.

Registrations will be accepted until 15 January 2024. Any cancellation for examinations must be done before end of February to avoid being charged registration fee.

The examinations consist of one three-hour paper for each course. Exams are written in Midrand only.

(All queries related to the examination scripts and or examination remarking must be dealt with ICT (London) directly.)

Minimum entrance requirements
Grade 12

One day compulsory revision workshop is held in Midrand only in April 2024 prior to the examinations in May.

ICT EXAMS STAGE 2, 3 and ACT time: 11h00 – 14h00

SCT 50

moduralized self-study
Advanced Concrete Technology

Moduralised self-study course offered by CCSA in preparation for stage 4 Advanced Concrete Technology examinations set by the Institute of Concrete Technology (ICT) based in London.

The Advanced Concrete Technology (ACT) diploma enjoys world-wide acceptance as the leading qualification in concrete technology and is examined by the UK based Institute of Concrete Technology (ICT). The ICT sets high educational standards and requires its members to abide by a code of professional conduct, thus enhancing the profession of concrete technology.

The SCT 50 will consist of five modules, listed below, which copies the structure of the new Fulton’s 10th edition. The set book for the course will be Fulton’s 10th edition. Delegates on the programme will also be supplied with supplementary reading material to ensure all topics in the ICT stage 4 syllabus are covered. Each of the first four modules will have a workbook that will be required to be handed in on completion of the module. This workbook will be assessed and commented on by a lecturer at SCT. Satifactory completion of the module work book will enable a delegate to proceed to the next module.

The only entrance requirement to be admitted onto the SCT 50 programme will be a pass in both the ICT stage2 (SCT 41) and stage3 (SCT 42) examinations. There will be no exceptions to this entrance requirement.
The moduralised self-study approach has been adopted to ensure a better quality of concrete technology education.

It allows the delegate more time to study each topic in detail while reducing the impact on his or her work environment. It also allows for incremental payment. By paying per module no large upfront payment is needed.

The modules are divided under the following topics:
Module 1: Materials and mixes
Module 2: Concrete properties
Module 3: Concrete manufacture, site practices, quality control and non-destructive testing
Module 4: Special concretes and techniques
Module 5: Concrete sustainability, Statistics for concrete and Advanced Concrete Technology project

Delegates will be allowed to enroll in up to two modules at a time and will only be able to enrol in further modules on satisfactory completion of a module work-book.

Applications to do SCT 50 modules can be made at any time.

Entrance requirements
Pass in both the ICT Stage 2 (SCT 41) and Stage 3 (SCT 42) examinations.
No exceptions will be entertained.
