Abstract
According to the invention there is provided A hydraulic lime composition including between 1 and 20% by weight of a Pozzolanic material which has a surface area of between 2 and 1000 m2g−1 when measured by BET N2 porosimetry, and an average particle size in the range 0.1 to 1000 μm.
Claims20
A hydraulic lime composition including between 1 and 20% by weight of a pozzolanic material which has a surface area of between 50 and 800 m2/g−1 when measured by BET N2 porosimetry, and an average particle size in the range 0.1 to 1000 μm.
A method of making a mortar or plaster formulation comprising the step of using a pozzolanic material having a surface area of between 50 and 800 m2/g−1 when measured by BET N2 porosimetry, and an average particle size in the range 0.1 to 1000 μm.
A method of preparing a hydraulic lime composition including the steps of:
- providing a pozzolanic material which has a surface area of between 50 and 800 m2/g−1 when measured by BET N2 porosimetry, and a particle size in the range 0.1 to 1000 μm;
- and blending said pozzolanic material with i) calcium hydroxide, or ii) a mixture of calcium hydroxide and calcium oxide or iii) calcium oxide prior to slaking, or iv) calcium carbonate prior to calcination;
- wherein the step of blending is performed so that the hydraulic lime composition contains between 1 and 20% by weight of the pozzolanic material.
