STUDY OF PIGMENTS FOR MATERIALS CONTAINING CEMENT

ETUDE DES PIGMENTS POUR LES MATERIAUX A BASE DE CIMENT.

Measurements carried out on approximately 100 products have facilitated the determination of the influence of pigments on the setting, stability, variations in length during curing in the air, under water or during accelerated ageing cycles, and the evolution in colorimetric properties. Accelerated ageing tests were carried out with the weather-o-matic device, natural ageing tests by exposure in a rural environment for a period of two years. The tests carried out on concrete showed the influence of pigments on: the bulk density, air content, absorption of water by capillarity and immersion, longitudinal and transverse dynamic elastic moduli after curing under water and during freezing-thawing cycles, variations in length of the samples and their mechanical, flexural and compressive strength. Inorganic pigments did not, generally, have an unfavourable effect. Pigments containing iron oxide have, however, very low colouring property. Pigments containing chromiumoxide have low colouring property which is however greater than that of blue inorganic pigments which tend to make the material to which they are added, brittle. Organic pigments give a far more intense colour and can be used in lower concentration but they markedly increase the sensitivity of concrete to frost. /TRRL/
