The possibility to obtain sulphoaluminate additive (SAA)
consisting of the necessary quantity of aluminium sulpfate and aluminium
hydroxide using water purification slimes is shown. It was
fixed that the admixture of crystallized (SAA) with cement provides
cement paste reinforce and structure formation at the share of ettringite
crystals which make cement paste to be shrinkage compensative
and expansive.
