Maaddad leh dareere wanaagsan ka dib marka lagu qaso biyaha, oo sidoo kale loo yaqaan walxo shubaya. Ka dib marka la qaabeeyo, waxay u baahan tahay in si habboon loo bogsiiyo si ay u noqoto mid isku urursan oo adag. Waxaa loo isticmaali karaa ka dib marka la dubo iyadoo loo eegayo nidaam gaar ah. Maaddada isku-dhafka ah waxay ka samaysan tahay aluminium silicate clinker, corundum material ama alkaline refractory clinker; maaddada daadinta ee fudud waxay ka samaysan tahay perlite ballaaran, vermiculite, ceramsite iyo alumina godan. Maaddadu waa sibidhka calcium aluminate, galaaska biyaha, ethyl silicate, polyaluminum chloride, dhoobo ama fosfate. Isku-darka waxaa loo isticmaalaa iyadoo ku xiran codsiga, shaqadooduna waa inay hagaajiyaan waxqabadka dhismaha iyo inay hagaajiyaan sifooyinka jireed iyo kiimikada.
Habka dhismaha ee walxaha lagu buufiyo waxaa ka mid ah habka gariirka, habka bamgareynta, habka duritaanka cadaadiska, habka buufinta, iyo wixii la mid ah. Dahaarka grout-ka waxaa badanaa loo isticmaalaa iyadoo lala kaashanayo biraha ama dhoobada. Haddii lagu daro xoojin bir ah oo aan miridh lahayn, waxay hagaajin kartaa iska caabintiisa gariirka farsamada iyo iska caabbinta shoogga kulaylka. grout-ka waxaa loo isticmaalaa dahaar ahaan foornooyinka daaweynta kulaylka kala duwan, foornooyinka kalcining-ka ee macdanta, foornooyinka dillaaca catalytic-ka, foornooyinka dib-u-habaynta, iwm., waxaana sidoo kale loo isticmaalaa dahaar foorno dhalaalaysa iyo haan biyo-dhalaal heerkul sare leh, sida foorno dhalaalaysa oo rasaas-zinc ah, qubeys qasacad ah, qubeys milix leh. Foorno, tuubo ama tuubo, durbaan bir ah, tuubada qalabka nadiifinta wareegga birta dhalaalaysa, iwm.
