There is not a simple way to explain which is better - whether it is concrete or screed. The right answer would be that it can be decided which is better depending on certain criteria one would have in mind. For example, screed tends to be smoother than concrete because of the fine sand and cement in the mixture. Therefore, it is better to use it as a finishing or top layer. On the other hand, concrete is stronger and lasts a lot longer. So, it is not wrong to say that it is better to use concrete for construction purposes. Both screed and concrete can be used indoors, while cement is the better choice for outdoor usage. As for the application, the screed is better because of the easier application process.
