The Compressive Strength of High-Performance Concrete and Ultrahigh-Performance

الملخص EN

The compressive strength of silica fume concretes was investigated at low water-cementitious materials ratios with a naphthalene sulphonate superplasticizer.

The results show that partial cement replacement up to 20% produce, higher compressive strengths than control concretes, nevertheless the strength gain is less than 15%.

In this paper we propose a model to evaluate the compressive strength of silica fume concrete at any time.

The model is related to the water-cementitious materials and silica-cement ratios.

Taking into account the author's and other researchers’ experimental data, the accuracy of the proposed model is better than 5%.
