The\u00a0“osmotic cements”<\/strong>\u00a0are cementitious waterproofing products developed in Germany at the end of the 70s, based on an “osmotic model” of interpretation of the hydration and solidification processes of hydraulic binders.[\/vc_column_text][\/vc_column][\/vc_row][vc_row row_type=”row_full_center_content”][vc_column width=”1\/3″][vc_single_image image=”68″ img_size=”medium” alignment=”center” css_animation=”bottom-to-top” css=”.vc_custom_1480545498280{margin-top: 20px !important;}”][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”69″ img_size=”medium” alignment=”center” css_animation=”bottom-to-top” css=”.vc_custom_1480545506353{margin-top: 20px !important;}”][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”67″ img_size=”medium” alignment=”center” css_animation=”bottom-to-top” css=”.vc_custom_1480545513209{margin-top: 20px !important;}”][\/vc_column][vc_column css=”.vc_custom_1480680943073{margin-top: 25px !important;}”][vc_column_text]<\/p>\n

The partially anhydrous cement granule (C) represents the “concentrated solution;\u00a0the “cement gel” (B) is the semipermeable membrane;\u00a0while water (A) is the diluted solution.<\/p>\n

[\/vc_column_text][\/vc_column][\/vc_row][vc_row row_type=”row_full_center_content”][vc_column][vc_column_text]In the described context, the heat of hydration drastically reduces the efficiency and duration of the hydration process: the cement granules are only “partially hydrated”.\u00a0The experiments carried out had in fact highlighted the particular ability of tartaric acid derivatives to delay and balance the hydration processes, facilitating osmotic exchanges, gel stabilization and crystalline transition with the result of deeper and more complete hydration.\u00a0The better “balance” of the osmotic phase, made possible above all by catalysts based on derivatives of tartaric acid, resulted in significant increases in quality and performance, both in terms of diffusion, adherence and intrinsic impermeability of the binder matrix.[\/vc_column_text][\/vc_column][\/vc_row][vc_row row_type=”row_full_center_content” bg_image=”185″ bg_position=”center center” row_parallax=”false” padding_top=”100″ padding_bottom=”100″][vc_column][vc_custom_heading text=”THE CEMENTITIOUS WATER BARRIER,

The particular adhesion of these systems, determined by the deep osmotic diffusion, also made them suitable for operating both in conditions of direct thrust (positive thrust) and negative (counter thrust).<\/strong>[\/vc_column_text][\/vc_column][\/vc_row][vc_row row_type=”row_full_center_content” class=”gruppoBtns”][vc_column width=”1\/4″][vc_button title=”Adhesion mechanisms” color=”custom” button_custom_color=”#00a5cc” position=”center” link=”url:https%3A%2F%2Fwww.osmocem.com%2Ftechnology%2Fadhesion-mechanisms%2F|title:Adhesion%20mechanisms||”][\/vc_column][vc_column width=”1\/4″][vc_button title=”Hydrostatic thrust” color=”custom” button_custom_color=”#00a5cc” position=”center” link=”url:https%3A%2F%2Fwww.osmocem.com%2Ftechnology%2Fhydrostatic-thrust%2F|title:Hydrostatic%20thrust||”][\/vc_column][vc_column width=”1\/4″][vc_button title=”Practical advice” color=”custom” button_custom_color=”#00a5cc” position=”center” link=”url:https%3A%2F%2Fwww.osmocem.com%2Ftechnology%2Fpractical-advice%2F|title:Pratical%20advice||”][\/vc_column][vc_column width=”1\/4″][vc_button title=”Complete line” color=”custom” button_custom_color=”#00a5cc” position=”center” link=”url:https%3A%2F%2Fwww.osmocem.com%2Ftechnology%2Fcomplete-line%2F|title:Complete%20line||”][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
