Abstract | En herdegipsinneholdende sammensetning legges frem. I en utførelsesform inkluderer den herdegipsinneholdende sammensitningen en sammenbindende matrise av herdegipsen dannet fra minst kalsinert gips, vann og et forbedrende materiale. Det forbedrende materialet kan velges ut fra i) en organisk polyfosfonforbindelse, eller en blanding derav; ii) et borat valgt ut fra uleksitt, kolmenitt, eller en blanding derav; eller en blanding av i) og ii). I en annen utførelsesform, behandles den herdegipsinneholdende sammensetningen med et forbedrende materiale som kan velges ut fra i) en organisk fosfonforbindelse eller en blanding derav, ii) et borat valgt ut fra uleksitt, kolmenitt eller en blanding derav; iii) en karboksylforbindelse eller en blanding derav; eller en blanding av i), ii) og/eller iii).
The invention relates to a set gypsum composition that demonstrates enhanced resistance to permanent deformation and/or enhanced dimensional stability and provides an accelerator for an aqueous calcined gypsum composition comprising a borate and an accelerator material. Optionally, the accelerator material is calcium sulfate dihydrate. Optionally, the borate and the accelerator material are provided in a milled mixture which optionally has a median particle size of less than about 5 µm and/or a surface area of at least about 7,000 cm 2 /gram. |
