Specialist in Cementitious
Solutions.
Background Raw Materials Clinker Microscopy Secondary Raw Materials Limestone Chalk Cement Chemistry Quality Solutions
My experience comes from over 35 years working with cement
and concrete and what I offer is a materials and process based approach to the science and
practice involved in the business. I take an unbiased,
objective view of
data
relating to new ventures, current issues and old problems,
producing reports dedicated to providing practical resolutions.
- Originally trained as a
geologist, I have experience of raw materials evaluation for cement
manufacture and of sourcing and assessment of sand and gravel
aggregates.
- Based
on
experience
with wet, semi-wet, semi-dry, dry and precalciner kilns and with raw
materials ranging from a two component ideal marl and chalk to a blend
of eight different raw materials from as many different sources, I have
worked to optimise the process to suit the materials and the materials
to suit the process, depending on the room for change in either area.
My
assessments relating to cement manufacture are directed towards
identifying the optimum utilisation for each situation.
- I
have
carried out research into the nature of cement hydration products
formed from fly ash, ground granulated slag, silica fume and metakaolin
as well as cement clinker and have developed
methods
of problem solving using microscopy as well as conventional chemical
and
physical data.
- I
have written concrete specifications for high profile projects such
as London's Heathrow Express tunnels and have specialised in the
design of wet mixes for sprayed concrete tunnel linings.
- My
experience is laboratory, field and plant based. I use
research as a means to provide practical solutions rather than an
excercise in itself.
