| 87 | Particle packed cement-SCM blends | US14343136 | 2012-10-17 | US08974593B2 | 2015-03-10 | John M. Guynn; Andrew S. Hansen |
| Cement-SCM blends employ particle packing principles to increase particle packing density and reduce interstitial spacing between the cement and SCM particles. Particle packing reduces the amount of water required to obtain a cement paste having a desired flow, lowers the water-cementitious material ratio (w/cm), and increases early and long-term strengths. This may be accomplished by providing a hydraulic cement fraction having a narrow PSD and at least one SCM fraction having a mean particle size that differs from the mean particle size of the narrow PSD cement by a multiple of 3.0 or more to yield a cement-SCM blend having a particle packing density of at least 57.0%. | ||||||

| PURPOSE: To increase a basicity of a blast furnace slag and to effectively utilize a converter slag as a starting material of cement by using as a component modifier the converter slag which had been conventionally subjected to disposal while spending expense since it is difficult to use as a cement material, etc. CONSTITUTION: At least one kind of the blast furnace slag and the converter slag to be mixed is in a molten state, and the slags are mixed to form a mixed slag having a composition of 95-70wt.% blast furnace slag and 5-30wt.% converter slag, and after melting and uniformalizing the mixed slag, the molten slag is water-crushed, and a conventional portland cement is compounded to this water-crushed powder. <=30wt.% converter slag particles are added to the molten blast furnace slag, and mixed, and water-crushed, and the obtained water-crushed slag is ground so as to have a prescribed particle size to obtain the water-crushed powder. In this way, the converter slag which has been conventionally subjected to disposal while spending expense is capable of effectively utilizing as the cement material, and a performance of the blast furnace cement is improved. | ||||||
