Proprieties investigation of composition binder on basis of sulfatcontaining cement and portland cement
Sulfatcontaining cement has been received from low aluminate and anthropogenic raw materials and is modification of sulfoaluminate cement. Composition binder on basis of sulfatcontaining cement and Portland cement subject to ratio between components is characterized by increased ettringite and decreased Ca(OH)<sub>2</sub> content in cement stone, short setting times, high early strength or high strength after 28 day hardening and is expending or non-shrinking.
