Abstract | This cement admixture contains calcium carbonate and calcium oxide in each particle thereof. The mass ratio (calcium carbonate/calcium oxide) between this calcium carbonate and calcium oxide is 25/75 to 99.5/0.5. The total of the calcium carbonate and calcium oxide in the cement admixture is 80 mass% or more.
L'invention concerne un adjuvant cimentaire contenant du carbonate de calcium et de l'oxyde de calcium dans chacune de ses particules. Le rapport massique (carbonate de calcium/oxyde de calcium) entre ce carbonate de calcium et cet oxyde de calcium est de 25/75 à 99,5/0,5. Le total du carbonate de calcium et de l'oxyde de calcium dans le mélange cimentaire représente 80 % en masse ou plus.
一粒子中に、炭酸カルシウム及び酸化カルシウムを含むセメント混和材であって、前記炭酸カルシウムと前記酸化カルシウムの質量比(炭酸カルシウム/酸化カルシウム)が25/75~99.5/0.5であり、前記炭酸カルシウム及び前記酸化カルシウムの合計が前記セメント混和材中80質量%以上であるセメント混和材。 |
