Isi ihe e ji mineral mee na ígwè ndị e ji ígwè rụọ bụ quartz, nke na-enweghị obere ọrụ pozzolanic n'ọnọdụ ebumpụta ụwa. Otu esi eme ka "ọrụ pozzolanic" nke ígwè ndị e ji ígwè rụọ dịkwuo mma abụrụla isi okwu nke ndị nchọpụta ugbu a. Dịka otu n'ime ụzọ ndị a na-ejikarị eme ihe maka ịgba ígwè ndị e ji ígwè rụọ ọrụ, igwe e ji ígwè arụ ọrụ nwere ike ibelata ike ịgba ígwè ndị e ji ígwè rụọ ọrụ ma mepụta ọtụtụ ntụpọ lattice na mgbanwe plastik. Nnyocha ahụ na-egosi na igwe e ji ígwè arụ ọrụ nwere ike ịkpalite ọrụ pozzolanic nke usoro mineral nkịtị na ígwè ndị e ji ígwè rụọ ọrụ. Ka nha ihe ndị e ji mineral ndị e ji ígwè rụọ na-ebelata, quartz nwere ike imeghachi omume na Ca (OH) 2 na simenti slurry iji mepụta gel calcium silicate amorphous hydrated na kristal ettringite na ngwaahịa mmiri ndị ọzọ. Nnyocha ahụ gosiri na mgbe igwe e ji gwerie ihe karịrị nkeji iri anọ, akụkụ dị nkọ nke ígwè e ji gwerie ihe na-ebelata nke ọma, a na-egosikwa obere ihe ndị dị na ya, a na-emekwa ka nha nha ahụ dịkwuo mma nke ukwuu. Na sistemụ calcium oxide nke anhydrite iron, enwere ike ịgwakọta siliceous iron e ji gwerie ihe na 30% iji kwadebe simenti 32.5. N'okpuru ọnọdụ nke obere oke ihe na-ejikọta mmiri, ntụ ntụ ígwè e ji gwerie ihe nwere ike ịkwalite mmiri mmiri mbụ nke simenti e ji gwerie ihe, mee ka nhazi oghere nke mortar dịkwuo obere, ma melite ike mbụ. Mmụba nke mpaghara elu kpọmkwem nke ígwè e ji gwerie ihe enweghị mmetụta doro anya na imeziwanye ihe ngosi ọrụ ya; Mgbanwe nke okpomọkụ e ji gwerie ihe nwere ike ime ka ihe ngosi ọrụ dịkwuo elu nke ukwuu na mbido (7d), mana enweghị mmetụta dị ukwuu na ihe ngosi ọrụ na ngwụcha (28d). Maka sistemụ ígwè e ji gwerie ihe na slag, enwere ike imeziwanye ihe ngosi ọrụ site na imeziwanye usoro egwere ihe, si otú a na-eme ka ike nke simenti dịkwuo mma. Ojiji ezi uche dị na ya nke ihe na-ebelata mmiri nwere ike ime ka ọdịnaya nke ígwè e ji gwerie ihe na simenti nkịtị dịkwuo elu site na 30% ruo 40%. Ịkpụcha ígwè nwere ike ime ka arụmọrụ ịkpụcha ya ka mma site na mmetụta nke ya, si otú a na-akpali ọrụ pozzolanic nke ígwè ọdụdụ. Site n'ịhazi oke nke ígwè ọdụdụ, slag, clinker na gypsum composite simenti, enwere ike ịkwadebe simenti arụmọrụ dị elu nke na-emezu ọkọlọtọ mba.
