[vc_row row_type=”row_full_center_content”][vc_column][vc_column_text]Les utilisations habituelles des rev\u00eatements en ciment osmotique<\/strong>, envisagent des situations dans lesquelles il faut emp\u00eacher le liquide de “sortir” (figures A et D) et des applications dans lesquelles il faut emp\u00eacher le liquide de “rentrer” (figures B et C).<\/p>\n

Le r\u00e9sultat est des conditions de fonctionnement soumises \u00e0 une pouss\u00e9e hydrostatique positive (pouss\u00e9e)<\/strong> et une pouss\u00e9e hydrostatique n\u00e9gative (contre-pouss\u00e9e)<\/strong>.<\/p>\n

Dans les images suivantes :
\nLa condition de pouss\u00e9e hydrostatique positive (soul\u00e8vement)<\/strong>, se produit lorsque le liquide exerce une pression directement sur le rev\u00eatement, qui est alors comprim\u00e9 sur le support : images A et B;
\nLa condition de pouss\u00e9e hydrostatique n\u00e9gative (contre-pouss\u00e9e)<\/strong>, se produit lorsque le liquide exerce une pression \u00e0 l’interface d’adh\u00e9rence du rev\u00eatement, exer\u00e7ant une pression visant \u00e0 d\u00e9tacher le rev\u00eatement du support : images C et D.<\/p>\n

NB<\/strong> : Dans les images, le rev\u00eatement osmotique est indiqu\u00e9 par la lettre (O).[\/vc_column_text][\/vc_column][\/vc_row][vc_row row_type=”row_full_center_content” margin_top=”0″ margin_bottom=”0″ padding_top=”0″ padding_bottom=”0″][vc_column width=”1\/4″][vc_single_image image=”1172″ img_size=”full” alignment=”center” css_animation=”bottom-to-top”][\/vc_column][vc_column width=”1\/4″][vc_single_image image=”1178″ img_size=”full” alignment=”center” css_animation=”bottom-to-top”][\/vc_column][vc_column width=”1\/4″][vc_single_image image=”1174″ img_size=”full” alignment=”center” css_animation=”bottom-to-top”][\/vc_column][vc_column width=”1\/4″][vc_single_image image=”1176″ img_size=”full” alignment=”center” css_animation=”bottom-to-top”][\/vc_column][\/vc_row][vc_row row_type=”row_full_center_content” margin_bottom=”0″ padding_bottom=”0″][vc_column][vc_column_text]Alors que dans la pr\u00e9sence de pouss\u00e9es hydrostatiques positives (1)<\/strong>, la caract\u00e9ristique la plus importante est l’imperm\u00e9abilit\u00e9 intrins\u00e8que, dans la pr\u00e9sence de pouss\u00e9es hydrostatiques n\u00e9gatives (2)<\/strong>, comme dans le cas de mouvements structurels, c’est l’adh\u00e9sion au support qui prend une valeur fondamentale.<\/p>\n

Pour atteindre pleinement la performance de l’imperm\u00e9abilisation cimentaire osmotique, surtout en contre-pouss\u00e9e, la porosit\u00e9 du support (qui dans le b\u00e9ton est \u00e9gale \u00e0 environ 200,000,000\/m\u00b2), est une ressource qui doit \u00eatre “ouverte” \u00e0 la diffusion osmotique ![\/vc_column_text][\/vc_column][\/vc_row][vc_row row_type=”row_full_center_content” margin_top=”0″ padding_top=”0″][vc_column width=”1\/3″][vc_single_image image=”91″ img_size=”full” alignment=”center” css_animation=”bottom-to-top”][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”92″ img_size=”full” alignment=”center” css_animation=”bottom-to-top”][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”93″ img_size=”full” alignment=”center” css_animation=”bottom-to-top”][\/vc_column][\/vc_row][vc_row row_type=”row_full_center_content” class=”gruppoBtns”][vc_column width=”1\/4″][vc_button title=”Histoire” color=”custom” button_custom_color=”#00a5cc” position=”center” link=”url:https%3A%2F%2Fwww.osmocem.fr%2Ftechnologie%2Fhistoire%2F|title:Histoire”][\/vc_column][vc_column width=”1\/4″][vc_button title=”M\u00e9canismes d’adh\u00e9sion” color=”custom” button_custom_color=”#00a5cc” position=”center” link=”url:https%3A%2F%2Fwww.osmocem.fr%2Ftechnologie%2Fmecanismes-dadhesion%2F|title:M%C3%A9canismes%20d’adh%C3%A9sion”][\/vc_column][vc_column width=”1\/4″][vc_button title=”Conseils pratiques” color=”custom” button_custom_color=”#00a5cc” position=”center” link=”url:https%3A%2F%2Fwww.osmocem.fr%2Ftechnologie%2Fconseils-pratiques%2F|title:Conseils%20pratiques”][\/vc_column][vc_column width=”1\/4″][vc_button title=”Ligne compl\u00e8te” color=”custom” button_custom_color=”#00a5cc” position=”center” link=”url:https%3A%2F%2Fwww.osmocem.fr%2Ftechnologie%2Fligne-complete%2F|title:Ligne%20compl%C3%A8te”][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
