1 NATURAL CEMENT LE PROMPT VICAT 28/11/2008

2 2 VICAT GROUP Originally, a scientific discovery In 1817, Louis Vicat invents the artificial cement during the construction of the bridge of Souillac

3 3 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

4 VICAT IS NOW AN INTERNATIONAL GROUP WORKING IN 11 COUNTRIES 4

5 the oldest plant of Vicat La Pérelle

6 the first plant Porte de France

7 7 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 8 At the present time we produce the natural cement in two plants and two underground quarries La Pérelle Saint-Egrève

9 9 At the present time we produce the natural cement with the same traditional process of vertical kiln than in 19 century La Pérelle plant

10 10 At the present time we produce the natural cement with the same traditional process of vertical kiln than in 19 century La Pérelle plant About

11 11 Extraction of the raw material in an underground quarry

12 12 A burning with a large spectrum of temperature

13 13 A simple grinding without addition

14 14 A part of electricity of La Pérelle plant is supplied by local hydroelectric energy

15 15 The Vicat natural cement complies with two French standards NF P defines the specifications for Prompt Natural Cement NF P defines the cements allowed for work at the sea The Vicat natural cement complies with European Technical Approval for the CE mark

16 16 We produce more than tons per year shipped mainly in Europe

22 BUT WHAT IS A NATURAL CEMENT? 22 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

54 54 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),
