Kuraho rwose umwanda wa peteroli hejuru ya sima, usukure umucanga n'umukungugu, ubushuhe, kugirango umenye neza ko ubuso, butanduye, butine, nta mavuta. Ibirimo byamazi ntibigomba kurenza 6%, agaciro k ntabwo karenze 10. Icyiciro cyimbaraga cya cement ntabwo kiri munsi ya C20.
Ubushyuhe bwo hasi ntabwo ari munsi ya 5 ℃, kandi byibuze 3 ℃ kuruta ubushyuhe bwikirere, igihu, imvura, urubura nimvura bibujijwe kubaka cyane.
1, ubike kumurongo wa 25 ° C cyangwa ahantu hakonje kandi humye. Irinde izuba, ubushyuhe bwinshi cyangwa ubushyuhe bwinshi.
2, koresha vuba vuba bishoboka iyo yafunguwe. Birabujijwe rwose gushyira mu kirere igihe kinini nyuma yo gufungura kugirango wirinde kwibasira ubwiza bwibicuruzwa. Ubuzima bwa Sholf ni amezi atandatu mubushyuhe bwicyumba cya 25 ° C.
