New Data Availability System
A new Data Availability System is being developed by ECHA. To begin with this system will take over the responsibility of making REACH registration data available, once it is ready. We expect the first version to be publicly available by the end of January 2024.
Since ECHA aims to devote our maximum effort to this new system, we can no longer maintain REACH registration data on the current Dissemination Platform. As such once the IUCLID format change begins on 19th May 2023 we will no longer update REACH registered substance factsheets. The factsheets will remain online, but will not be updated.
As a consequence, REACH registration data will likewise not be updated in Infocards, Brief Profiles, the Advanced search, or the Nanomaterials on the EU market portal. We will inform you of what you can expect in the new System, along with details of when and where to find it.
We appreciate your understanding in the meantime.
Cement, portland, chemicals
Portland cement is a mixture of chemical substances produced by burning or sintering at high temperatures (greater than 1200°C (2192°F)) raw materials which are predominantly calcium carbonate, aluminium oxide, silica, and iron oxide. The chemical substances which are manufactured are confined in a crystalline mass. This category includes all of the chemical substances specified below when they are intentionally manufactured in the production of Portland cement. The primary members of the category are Ca2SiO4 and Ca3SiO5. Other compounds listed below may also be included in combination with these primary substances.@CaAl2O4@Ca2Al2SiO7@CaAl4O7@Ca4Al6SO16@CaAl12O19@Ca12Al14Cl@Ca3Al2O6.@Ca12Al14F2@Ca12Al14O@Ca4Al2Fe2.@CaO@Ca6Al4Fe2.@Ca2Fe2O5.
