Abstract
Išradimas priklauso statybos pramonės sričiai, būtent hidraulinių kompozicinių rišiklių kalcio sulfato pagrindu gamybos sričiai. Išradimo tikslas pagerinti kompozicinio gipso cemento pucolanų rišiklio atsparumo šalčiui savybes, nedidinant liejinio tankio bei spręsti ekologines problemas, t. y. utilizuoti iki šiol nenaudojamas akmens vatos gamybos atliekas - žemakrosnės dulkes. Rišiklio sudėtis: kalcio sulfato rišiklis (pushidratis gipsas arba anhidritas) - (60 - 68) %, portlandcementis - (20 - 25) %, žemakrosnės dulkės (akmens vatos gamybos atlieka) - (12 - 15) %. Sukietėjusio rišiklio atsparumas šalčiui yra 150 - 200 ciklų (tūrinis šaldymas ir atšildymas).
