  • Patent number: 10131575
    Abstract: Quarry fines and/or limestone powder are used to reduce clinker content in concrete, mortar and other cementitious compositions, typically in combination with one or more pozzolanically active SCMs. Quarry fines and/or limestone powder can replace and/or augment a portion of hydraulic cement binder and/or fine aggregate. Quarry fines and/or limestone powder can advantageously replace a portion of cement binder and fine aggregate, acting as an intermediate that fills a particle size void between the largest cement particles and smallest fine aggregate particles. Supplemental lime can advantageously maintain or enhance balance of calcium ions in the mix water and/or pore solution. Supplemental sulfate can advantageously address sulfate deficiencies caused by high clinker reduction, use of water reducers and/or superplasticers, and SCMs containing aluminates.

  • Publication number: 20150144030
    Abstract: 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%.

It was surprisingly found that the binder system according to the invention hardens in the form of a hybrid matrix which is acid-resistant, water-resistant and alkali-resistant. The binder system can be used for the production of a hydraulically setting mortar which, after setting, hardening for seven days and subsequent storage for three days in acid, base and/or water, has compressive strengths of more than 15 N mm?2, preferably more than 20 N mm?2 and in particular more than 25 N mm?2, according to DIN EN 13888.

  • Publication number: 20130059099
    Abstract: The present invention relates to a cement-free alkali-activated binder. More particularly, the present invention relates to a cement-free alkali-activated binder having a novel combination ratio, which can improve the compressive strength of mortar and concrete in which the cement-free alkali-activated binder is used as a binding material instead of cement, and which can solve the low field applicability of mortar and concrete in terms of quick setting characteristics, fluidity loss, economic efficiency and the like, and to mortar or concrete comprising the same. The cement-free alkali-activated binder can improve field applicability by controlling the content and combination ratio of an alkali activator included in the cement-free alkali-activated binder, and can solve the problems of the toxicity of cement, the carbon dioxide (CO2) produced during the manufacturing of cement and the exhaustion of natural resources due to the production of cement.
