Originally, a scientific discovery

In 1817, Louis Vicat invents the artificial cement

during the construction of the bridge of Souillac

VICAT GROUP

VICAT GROUP

In 1853, his son, Joseph Vicat creates the first Portland cement

plant of the group Vicat at Genevrey-de-Vif in Isère department.

The vertical kiln called « bottle-feed » of Genevrey-de-Vif plant.

From 1853 to the present day, 7 generations of managers have

built the Vicat group, today the third French cement producer

4VICAT IS NOW AN INTERNATIONAL

GROUP WORKING IN 11 COUNTRIES

VICAT NATURAL CEMENT

At the present time we produce the natural cement with the same stone from the same geological seam in “ Chartreuse” mountain exploited for more than 150 years

8

At the present time we produce the natural cement in two plants and two underground quarries

La Pérelle Saint-Egrève


9

At the present time we produce the natural cement with the same traditional process of vertical kiln than in 19° century

Extraction of the raw material in an underground quarry


12

A burning with a large spectrum of temperature


13

A simple grinding without addition


14

A part of electricity of La Pérelle plant is supplied by local hydroelectric energy


15

The Vicat natural cement

complies

with two French standardsNF P15-314 defines the

specifications for Prompt

Natural Cement

NF P15-317 defines the

cements allowed for work

at the sea

The Vicat natural cement

complies with

European Technical Approval

for the CE mark


16

We produce more than 100 000 tons per year shipped mainly in

Europe

BUT WHAT IS A NATURAL CEMENT ?

Some definitions

Natural: a binder produced from marl or limestone containing clay,

one source material rather than being blended from different

sources; it is a natural combination of limestone and clay

This cement was called Roman cement in the north of river Loire

in France and every where in Europe, and Prompt cement in the

south of France

Roman: a derivation of the name of the ancient Roman lime and

pozzolana blends invented by the first English producers

Process : the same than natural hydraulic lime, burnt in vertical

shaft but without slaking just grinding

Main characteristics

Rapid setting ≈15 min

Warm yellow to brown colour

Minimal shrinkage

Rapid hardening then relatively slow

Natural cement in mixes with Natural Hydraulic Lime

add "liveliness" at an early age, thereby providing the lime with new properties to allow:

compressing the waiting period between layer applications

limiting shrinkage cracking, especially at early age;

curbing the excessive dehydration of early-age coatings

applying excess coating during a single run;

strengthening the points that feature natural vulnerability: edges, jambs;

working during cold weather periods, secure against freezing

The main properties of lime are kept: walls breath (vapour permeability), excellent adhesion, low e-modulus, with in addition a low shrinkage (reduction of cracks),
