Halka dib-u-dhacu uu beddelo wakhtiga dib-u-dhaca gypsum-ka, waxa kale oo uu si weyn u waxyeeleeyaa xoogga.
Faa'iidooyinka gypsum retarder:
Ku darida qadar yar, wakhti dheer oo dib u dhac ah
Adayg sare ka dib xinjirowga, aan sun ahayn, dhadhan la'aan iyo in ka badan oo deegaanka saaxiibtinimo
1. Marka hore isku qas budada gypsum ee dhismaha iyo dib u dhigista, Yuhe hydroxypropyl methylcellulose ama wax kale oo lagu daro si siman, ka dibna ku dar ciid, kalsiyum culus, iwm, ku dar ciid ama kalsiyum culus oo walaaq 15 daqiiqo ka hor inta aanad sii deyn.(Fiiro gaar ah: Sababtoo ah cufnaanta gaarka ah ee kala duwan ee alaabta, waxaa jiri doona stratification ka dib walaaqaya muddada dheer, taas oo saameyn doonta tayada alaabta.)
2. Alaabooyinka kale, sida gypsum caaryada iyo biyaha jel ee dib u dhacay, waxaad gelin kartaa dib-u-dejiyaha biyaha marka hore, ka dibna ku dar si aad u isticmaasho ka dib marka la milmo.
