METHOD OF PRODUCING PORTLAND CEMENT HAVING ELECTRICAL CONDUCTION AND OPTICAL PROPERTIES

摘要

The invention relates to a method of producing conductive and/or translucent Portland cement which has high sulphate resistance and which has a service life of up to 70 years under normal service conditions. Once the inventive cement has set, light can pass therethrough. Up to 70 % of the final resistance of the cement is reached within 48 hours of setting. The inventive production method is characterised in that it produces a fineness of more than 3450 cm2/g and in that, upon setting, the concrete has a mechanical strength of between 75 MPa and 250 MPa, without the addition of additives, thereby enabling the water required to obtain a determined slump to be reduced.
