Problems solved by technology

This results in a strength drop of up to 25% of the total strength
The disadvantages of concrete preparation are numerous and include, in addition to the above-mentioned loss of properties, poor tensile strength, low chemical stability (especially acid stability), loss of strength in aggressive environments (such as nuclear power plants), and poor colorability , easy weathering and easy dehydration

Abstract

The invention relates to a composition having an inorganic phosphatic binder and filler material having a high specific surface area, and the use and production thereof.

Description

Compositions based on phosphate raw materials and methods for their preparation technical field The invention relates to a composition comprising an inorganic phosphate binder and a filler with a high specific surface area, as well as its use and preparation. Background technique Concrete is a type of man-made stone made from cement (hydraulic binder), concrete aggregate or stone particles and mixing water. Additionally, concrete additives and admixtures may be added to the mixture. The key material is the hydraulic binder, whose composition should ensure the best possible combination of target product properties. A variety of cements with different properties have been disclosed. This predominantly calcium silicate cement with aluminum and iron components is usually present as a complex mixture. After the addition of mixing water, this inorganic non-metallic solid automatically solidifies due to a chemical reaction. Cement reacts by absorbing mixed water (also in a hu...
