Abstract EN
Based on the existing experimental data for compressive strength values of different concrete mixes, a statistical analysis for the gathered data was conducted.
The analysis revealed a model for predicting the compressive strength of concrete mixes at any age with the help of two constants (A) and (B) that are considered as a characteristic property for a concrete mix.
The constant (A) is introduced as a rate of strength gain constant whereas, (B) is introduced as grade of strength constant.
Once the values of constants (A) and (B) are defined for a concrete mix, the compressive strength at any age could be simply predicted without collecting data at that age.
The values of (A) and (B) could be determined by one of two methods.
Solving two simultaneous equations at two different ages while performing either design or trial concrete mix is a method that could be used to define the two constants.
ther method is based on concrete strength at 28-day age.
The proposed model was studied for different concrete mixes.
The study covered some parameters including the influence of, mineral admixtures as a partial replacement of cement, metakaolin, nano silica fume, curing in water or lime and the effect of curing temperature.
The analysis reveals that mixes containing no admixtures, mixes containing silica fume and cured at normal temperature, mixes containing nano silica and cured in water are following with high accuracy the proposed model.
