Our Training Services
GR Technologie Ltd and our Sister Company MG Associates are two of the UK's
leading companies specialising in training in concrete and concrete repair.
The Directors of both companies lecture regularly on topics associated with
the inspection and repair of concrete. Training courses are presented at one of
several regional centres around the country. A range of courses is offered,
typical examples being presented below. Bespoke courses on any aspect of
construction practice, materials or construction management can be arranged
however. Please enquire for details. The course shown below is a two-day event,
with the first day devoted to understanding concrete as a material. This course
will be suitable for contractors, technicians who want to understand a little
more about concrete, and also as a refresher for Engineers. The "Concrete
for Engineers and Contractors" course can be combined with the course below
to make a 2 day event, or either day can be taken on its own.
We can also offer
bespoke courses in concrete practice, or in any aspect of materials or construction
management (see also the "Toolbox Talk" at the end of this section.

Description: A directory of training courses and
training consultants for all areas of management development and IT /
computer skills training. The directory holds details of over 25,000
scheduled public training courses and more than 120,000 dates for public
courses.
Comments from Previous Courses
"A very informative and useful course, well presented and brought
across"
"Very interesting and educational, well presented in a pleasant
atmosphere"
"I found this to be a very informative lecture with good reference to
practical situations"
"Very informative and interesting presentations. Well delivered, good,
clear course notes for future reference and to help focus on talk. Useful
demonstrations".
Costs are based on either £200 per day per head for public courses or
bespoke courses typically start at around £1000 per day (with a limit of about
15 on numbers) Plus VAT.
The "Toolbox Talk" offered at the end of this section is a new,
very short (about 1 hour) on-site chat, aimed at gangers, concreting staff and
foremen. It is intended that the cost of this should be as low as possible, but
given the short duration, the cost will obviously depend on the site location.
Please enquire for costs for your particular venue.
UNDERSTANDING CONCRETE
DEFECTS, DIAGNOSIS AND REPAIR
INTENDED FOR
Technicians and Engineers who need a basic understanding or revision of
concrete deterioration mechanisms, methods of diagnosis, and techniques for
concrete repair. The course is intended as a stand alone course or can be
combined with our course on Understanding Concrete, held the previous day, at
the same venue.

THE SPEAKER
Eur Chem Michael Grantham BA CChem FRSC IEng MIQA AMICT
Mike has worked for several of the major testing houses in a career spanning
some 30 years. He has been involved in a considerable amount of testing work on
bridges and other heavy structures such as; car parks, office buildings,
multi-storey flats, down to small scale problems with prc housing. He lectures
regularly for Thomas Telford Training on their courses.
TARGET BENEFITS
After the course, participants will have an understanding of deterioration
mechanisms for concrete, methods for diagnosis of these problems, including some
of the newer techniques such as linear polarisation, radar, infra red
thermography etc. They will understand how these techniques are applied in
diagnosis, how concrete repairs can effectively deal with the problems, and, for
bridge engineers, methods of testing both conventional and post tensioned and
prestressed bridges, including the latest remote monitoring techniques.

What is concrete:
constituents, cement, aggregates, steel, admixtures. Special problems
arising from the use of materials. Carbonation of concrete, calcium
chloride, high alumina cement. |
| |
Recognising concrete
defects: Structural cracks, reinforcement corrosion, alkali silica
reaction, frost damage, shrinkable aggregates, chemical attack, fire
damage, poor quality construction, plastic cracking - plastic settlement
and plastic shrinkage cracks. |
| 10:30 |
Coffee |
| 11:00 |
Investigation of defects -
the Two Stage Approach |
| |
Desk study, visual surveys,
covermeter survey, ultrasonic pulse velocity surveys, sampling by coring
and dust drilling, chemical analysis, determining compressive strength,
petrographic examination, rebound hammer, other near to surface tests -
the Windsor Probe, the LOK test, break off tests, sub surface radar,
infra red thermography. |

Questions and discussion |

Testing for reinforcement
corrosion: Half cell potential, resistivity, linear polarisation
measurements to determine corrosion rate of steel (section loss per
year). |
| 3:00 |
Tea |
| 3:30 |
Concrete repairs: the
patch repair approach - when to use and when not to use it,
understanding the cost implications and remeasurement. Electrochemical
repair: cathodic protection, realkalisation and desalination. What they
do, how they work, practical experience. Corrosion inhibitors, what they
are and do they work? |

All delegates will be given a certificate of
attendance. Full and detailed course notes, with photographs and illustrations
are provided as hard copy and on CD-ROM (80 pages).
CONCRETE FOR ENGINEERS AND CONTRACTORS
INTENDED FOR
Technicians and Engineers who need a basic understanding or revision of
concrete and its properties. The course is intended as a stand alone course or
can be combined with our course on Diagnosis Inspection Testing and Repair of
Concrete Structures held on the following day.

THE SPEAKER
Tony Binns- Spent the early part of his career producing, supervising and
dealing with Quality Control, before joining the staff of the C&CA’s
training centre. With them, he lectured for 14 years on concrete materials
topics including mix design and ready mixed concrete. Tony then spent two years
with a major civil engineering contractor and now runs his own training company
running courses in the UK and overseas.
TARGET BENEFITS
After the course, participants will have an understanding of the fundamental
properties of concrete and those of the mix ingredients, including admixtures
and reinforcement. Some concrete defects are introduced (with this theme
developed on the second day for those taking the 2 day course). Participants
will also understand how concrete is specified using British Standards. They
will also understand the steps that are taken when non-conformity of the
concrete occurs.
