L\u00e9g\u00e8ret\u00e9 et r\u00e9sistance.<\/h2>\n

\u2022<\/span> La conductivit\u00e9 thermique du b\u00e9ton est directement corr\u00e9l\u00e9e \u00e0 sa densit\u00e9. Ces \u00e9l\u00e9ments sont connus et analys\u00e9s de fa\u00e7on pr\u00e9cise depuis plus d\u2019une vingtaine d\u2019ann\u00e9e.<\/p>\n

\u2022<\/span> Les performances m\u00e9caniques atteintes avec des b\u00e9ton d\u2019ardoise expans\u00e9es vont de 10 \u00e0 50 Mpa.<\/p>\n

\u2022<\/span> Ces performances permettent \u00e0 Granulex\u00ae<\/span> de r\u00e9pondre aux exigences des concepteurs d\u2019ouvrages d\u2019art mais \u00e9galement d\u2019offrir le confort d\u2019utilisation d\u2019un b\u00e9ton traditionnel en travaux neuf comme en r\u00e9novation, la l\u00e9g\u00e8ret\u00e9 en plus.<\/p>\n

\u2022<\/span> La faible absorption du Granulex\u00ae<\/span> permet ais\u00e9ment la r\u00e9alisation de formules pompables, adapt\u00e9es aux diff\u00e9rents usages du b\u00e9ton l\u00e9ger. Ouvrages d\u2019arts, r\u00e9novation\u2026<\/p>\n

Baplite.<\/h2>\n

L\u00e9ger, structurel \u2026 et auto pla\u00e7ant !<\/h3>\n

\u2022<\/span> Bien qu\u2019il soit jusqu\u2019\u00e0 60 % plus l\u00e9ger qu\u2019un agr\u00e9gat traditionnel, GRANULEX\u00ae permet ais\u00e9ment la r\u00e9alisation de b\u00e9tons autopla\u00e7ants.<\/p>\n

\u2022<\/span> Sa faible absorption permet un maintient de rh\u00e9ologie conforme aux besoins des fabricants de b\u00e9ton pr\u00eats \u00e0 l\u2019emploi.<\/p>\n

\u2022<\/span> Baplite p\u00e8se 1650 kg \/ m3, soit un gain de 30 % par rapport \u00e0 un b\u00e9ton traditionnel. Suivant les formulations, les b\u00e9ton autopla\u00e7ants peuvent atteindre des r\u00e9sistances m\u00e9caniques allant jusqu\u2019\u00e0 50 Mpa.<\/p>\n

Un granulat coupe feu.<\/h2>\n

\u2022<\/span> Utilis\u00e9 dans de nombreux b\u00e9tons r\u00e9fractaires, Granulex\u00ae<\/span> am\u00e9liore le comportement au feu de vos mat\u00e9riaux.<\/p>\n

\u2022<\/span> En effet, la multitude d\u2019alv\u00e9ole qui le compose permet de freiner le flux de chaleur.<\/p>\n

\u2022<\/span> Totalement incombustible, Granulex\u00ae<\/span> ne provoque aucun d\u00e9gagement gazeux lorsqu\u2019il est en contact avec le feu, ce qui d\u00e9marque les b\u00e9tons de Granulex\u00ae<\/span> des autres b\u00e9tons l\u00e9gers.<\/p>\n

\u2022<\/span> Les b\u00e9tons \u00e0 base d\u2019ardoise expans\u00e9es sont reconnus pour leurs performances dans de nombreux pays et ont contribu\u00e9 \u00e0 la r\u00e9alisation d\u2019ouvrages hautement techniques.<\/p>\n

\u2022<\/span> Ouvrage prestigieux r\u00e9alis\u00e9 en Ardoise Expans\u00e9e, le Golden Gate, construit \u00e0 San Fransisco en 1933 symbolise la r\u00e9sistance des b\u00e9tons l\u00e9gers structurels. Pont suspendu le plus long du monde, il n\u2019aurait pu voir le jour sans l\u2019association unique de l\u00e9g\u00e8ret\u00e9 et de r\u00e9sistance que repr\u00e9sentent les granulats d\u2019Ardoise Expans\u00e9e.\n<\/div>\n
