Abstract (en)

Water resistance of samples made from semi – hydrate gypsum (E – CaSO4 x 0.5 H2O) was investigated. Up – to – date method was applied for the samples formation by mechanical activation. It was established that the best water and frost resistance can be achieved for samples made from 70 % CaSO4 x 0,5 H2O, 20 % portland cement, 10 % microsilica and plastificator (0,25 % of portland cement mass). Keywords: extractive semi – hydrate gypsum, ettringite, thaumasite, mechanical activation.
