When the Blaine value is too large, the amount of kneading water increases, which may deteriorate the strength development and durability, and is preferably 8,000 cm 2 / g or less. The vitrification rate of the slowly cooled slag is preferably 30% or less,
% Or less is more preferable. If the vitrification ratio exceeds 30%, the heat of hydration may increase. Vitrification rate (X) is X
(%) = (1−S / S 0 ) × 100. here,
S is melilite (gerenite 2CaO.) Which is the main crystalline compound in the slowly cooled slag obtained by powder X-ray diffraction method.
(Solid solution of Al 2 O 3 · SiO 2 and akermanite 2CaO · MgO · 2SiO 2 )
The area of the main peak of S 0 is 1,000 for the slowly cooled slag.
The area of the main peak of melilite after heating at 0 ° C. for 3 hours and then cooling at a cooling rate of 5 ° C./min is shown. The amount of slowly cooled slag used is 5 to 300 per 100 parts of cement.
Parts are preferred, and 10-100 parts are more preferred. If it is less than 5 parts, the strength enhancing effect may not be fully exerted,
If it exceeds the number of parts, workability may deteriorate.
