MICROSIL 90 BIANCO consists of high purity (greater than 90%) silica fumes , selected, processed and bagged. Silica fume, the only component of MICROSIL 90 BIANCO, is created spontaneously during the production of silicon steel (special and limited production). For all intents and purposes, therefore, silica fume is nothing more than particles of SiO₂ released during machining processes of silicon metal and iron-silicon alloys, in the form of very fine powder with vitreous structure.
These micro-granules, purified and selected, have a variable size between 0.01 and 1 μm, therefore much finer than cement granules, and are characterised by very high pozzolanic reactivity. Silica fume has been used now for over than 40 years all over the world for the fundamental improvement of rheological and performance characteristics of concretes, mortars and special plasters where they are introduced.
From 10 to 30 kg of MICROSIL 90 BIANCO for each cubic metre of concrete to be made.
Production of sulphate-resistant, sulphate-resistant, anti-leaching mortars, plasters, grouts and concretes , high performance in terms of watertightness, mechanical resistance, chemical resistance etc., in the realisation of civil engineering and hydraulic structures and works in marine, mountain, urban atmospheres etc.
MICROSIL 90 BIANCO must be poured into a concrete mixer subsequently to other solid components of the mixture: cement and aggregates. After mixing for about 30 - 45" add the mixing water, where possible with the addition of FLUID S, continue to mix until a strictly homogeneous mixture is obtained. Prepare test mixtures in order to determine the most suitable mix.
- To be added to other components
- Cement-based or lime-based mortars
Protect and damp harden the mixtures obtained.
