Sementning qotish vaqtining tezligi bir qator omillarga bog‘liq. Ma’lumki, sement kukunining maydalik darajasining ortishi bilan solishtirma sirt yuzasining ortishi uning qotish vaqti tezlashadi. Ushbu tadqiqot ishida tabiiy sharoitda qotgan YuMB-100, ya’ni faqat portlandsement klinkeri va 3% gips toshidan tashkil topgan tarkiblari 28 sutkalik mustahkamligining mos ravishda 1 sutkada 20 dan to 23% gacha, 3 sutkada 53 dan to 58% gacha va 7 sutkada 68 dan to 77 % ga erishishi aniqlandi. Shuni ta’kidlash kerakki tarkibida 0,8% superplastifikator bo‘lgan tarkib 28 sutkada mustahkalik bo‘yicha eng yuqori ko‘rsatkich – 56,3 MPani ko‘rsatish bilan
birga, qotish vaqtiga mos ravishda 1 sutkasida 28 sutkalik mustahkamligining 23 %i, 3 sutkasida 53%i va 7 sutkasida 68 %iga erishdi.
