MB Series Concrete Modifiers
Each granule represents an aggregate of ultra-fines microsilica or a mixture of microsilica and fly ash or expansive compound uniformly covered by hardened thin adsorption layer of superplasticizer and other organic components. The hardened adsorption layer glues microfiller particles stimulating formation of granules, but at the same time, being waterЦsoluble, stimulates the granules de-aggregation being mixed with water during concrete manufacturing [4, 5, 75].
MB modifiers are designed for manufacturing of the High Performance Concrete including very high-strength concrete which generally may be obtained only by combined application of special cements with microsilica and superplasticizer.
However, in comparison with the required component of such concrete Ц microsilica, a light powder-like substance of 200 kg/m3 bulk weight (or 500 kg/m3 in compacted state) making transportation and technological problems, the modifiers are more workable and transportable and their application does not result in corresponding manufacturing costs increase.
