摘要：

Concrete has not only fulfilled the load-bearing function, but also its aesthetic function comes to the fore. It is precisely coloured concrete that performs this function best. The second phenomenon of today is "green concrete". In the paper, the properties of coloured concrete are compared with its "greener" alternative-coloured concrete with fly ash as a binder substitution. Experimental samples were measured for compressive strength and water absorption over a period of 7 days to 2 years. The results showed that the combination of coloured pigment and fly ash has an interesting synergistic effect, as evidenced by a 45MPa compressive strength and a 15% decrease of water absorption. © 2020 Trans Tech Publications Ltd, Switzerland.
