Tecplaster\u00ae Mortar - Protection of Mixed Slabs<\/h1>
<\/div><\/div>[vc_row_inner][vc_column_inner width=”2\/3″][vc_column_text css=””]<\/p>\n
Mixed concrete and steel sheet slabs were developed in the middle of the last century to improve the construction of skyscrapers in the United States. Indeed, they benefit from a quick execution without the need for shoring, a thinner edge, and a better resistance \/ weight relationship than a conventional slab. All these advantages make them ideal for a use in the construction of industrial, office and modular buildings, as well as in renovation work.<\/p>\n
When calculating the necessary thickness of protection, this type of slab is often treated as if it were a simple concrete slab. However, this is not correct. The main difference lies in the fact that this type of metal element with a large and thin surface has a critical temperature of 350\u00b0C, and not 500\u00baC like conventional concrete slabs.<\/p>\n
The R&D department of mcr tecresa\u00ae<\/strong>\u00a0has developed a new solution based on our Tecplaster\u00ae<\/sup><\/strong> mortar by passing the \u201cProtection of mixed slabs\u201d test according to the Standard UNE EN 13381-5. The test gave us an excellent result in terms of thickness, while achieving more than 240 minutes of fire protection.<\/p>\n

Aplication<\/h2>
<\/div><\/div>[vc_column_text]<\/p>\n
Tecplaster\u00ae<\/sup><\/strong> mortar is usually applied with spraying machines, with a pump and by wet projection. For manual application, in some cases, it is advisable to first place a metal mesh, properly fixed to the surface.<\/p>\n
Preparation of Tecplaster\u00ae<\/sup><\/strong> mortar: Add water to the mortar in an approximate ratio of 1 kg of dry mortar for 1 litre of water. The ratio between water and Tecplaster\u00ae<\/sup><\/strong> mortar will vary slightly depending on the desired consistency.<\/p>\n
Preparation of the surface: it must be clean, without traces of grease, dust, or other disaggregated elements. Metal surfaces must be treated with a primer layer.<\/p>\n
The finish of Tecplaster\u00ae<\/sup><\/strong> mortar is usually rough but it can also be smooth. It is also possible to paint directly on the mortar to obtain a personalized finish.<\/p>\n
Tecplaster\u00ae<\/sup><\/strong> mortar is for indoors applications. The atmosphere should be between 5\u00baC and 40\u00baC with low relative humidity.<\/p>\n
Tecplaster\u00ae<\/sup><\/strong> mortar should be stored on a flat surface and never outside. It must be protected from sunlight and moisture.<\/p>\n
