Abstract
The results of rheological characteristics of silica fume and aluminosilicate mineral water paste were studied out. defined their water demand (water requirement), mobility, calculated shear stress limit of mineral water paste by value of flowability on the border of the gravitational spread test. Shown concentration-water reducing sensitivity to Hyper - and super - plasticizers in silica and aluminosilicate systems.
Keywords: mineral additives, modifiers, rheological characteristics, silica fume, zeolite
