The review of the most commonly used models for assessment of the concrete strength development is presented. The simple time-dependent models proposed by ACI Committee 209, CEB FIP Model Codes, Eurocode 2 and JSCE are outlined in the paper. More complex model based on the degree of hydration is also discussed. These models have been validated to assess their usefulness in the prediction of the strength development of concretes with low clinker cements (LCC). The data for the validation came from experimental tests performed for concretes with different low clinker cements. The content of mineral additives (siliceous fly ash and ground granulated blast furnace slag) in the used cements was relatively high and reached even 67.7%. Some other results from literature have been also used for the assessment of the models. The performed validation of the models indicates that the time-dependent models describe the strength development of concretes with LCC in very approximate way. The results of the analysis also show that the model based on the degree of hydration describe the strength development of concretes with LCC much more accurately. In order to improve CEB FIP/Eurocode strength development model a new coefficient of this model is proposed.
