| titleOfInvention | Concrete with low clinker content |
| abstract | The present invention provides, in mass ratio, A Portland clinker in the form of grains having a Dv 97 of 10 to 30 μm or a Blaine specific surface area of 5300 cm 2 / g or more, preferably 5500 cm 2 / g or more, and - a dry binder pre-mix comprising slag, The minimum amount of clinker (unit: mass%) is determined according to formula (I) for clinker having Dv97 of 10 to 30 占 퐉 or according to formula (II) for clinker having bain surface area of 5300 cm2 / And, The formula (I) Here, Dv97 k is given as mu m, The formula (II) Here, BSS k is the blaine specific surface area (unit: cm 2 / g) of the clinker, In the case of a mixture with a clinker having a Dv 97 of 10 to 30 탆, the minimum amount (unit: mass%) of the slag is preferably in accordance with the formula (III), or in the case of a mixture with a clinker having a blast specific surface area of 5300 cm 2 / Is determined according to the formula (IV) The formula (III) Here, Dv 97 k is the Dv 97 of the clinker given in 탆, BSS S is the blast specific surface area (unit: cm 2 / g) of the slag, The formula (IV) Here, BSS k and BSS S are the blaine specific surface area (unit: cm 2 / g) of the clinker and the slag, respectively, Wherein the total amount of clinker in the binder premix is strictly less than 60%. The present invention also provides a dry binder mix obtained by mixing the dry binder premix with an aggregate, and a wet concrete composition obtained by mixing with water. |
