Evaluation of white cement coloured with ultramarine blue pigment
In this study the performance of white cement coloured with ultramarine blue pigment wasevaluated. The performance is explained through of the mineralogical changes occurring in the replacement of cement by pigment in percentages of 5, 10, 15 and 20%. It produced concrete and pastes to be studied to...
