SELF-LEVELLING CEMENT COMPOSITION WITH CONTROLLED SPEED OF DURABILITY DEVELOPMENT AND SUPERHIGH DURABILITY AT PRESSING AFTER SOLIDIFICATION AND PRODUCTS FROM IT Russian patent published in 2013 - IPC C04B28/02 C04B111/20 

FIELD: chemistry.

SUBSTANCE: self-planning cement mixture with excellent rheological properties, which solidified with controlled speed of durability development in composite composition of ultrahigh compressive strength for application in production of products, such as cement armor-plates with properties of ballistic and explosive resistance. Non-shrinkable cement composition, contains permanent phase, obtained as a result of solidification of self-levelling water cement mixture, in absence of quartz powder, which includes, wt %: 25-45 of inorganic cement binding agent, 35-65 wt % of inorganic mineral filler with particle size from approximately 150 to approximately 450 micron, 5-15 wt %: trass filler with average particle size less or equal 50 micron, 0.25-5.0 wt % of polycarboxylate-based self-levelling agent and 6-12 wt % of water. Invention also relates to armor-plate and to protective barrier, made from claimed solidified mixture. Invention is developed in dependent ii of invention formula.

EFFECT: obtaining self-levelling cement mixture with excellent rheological properties.
