A Simple Model of Predicting The Degree of Hydration of Concrete Using Artificial Neural Networks Dengxiang Zhang 1, a, Weijun Yang 2,b 1 College of Hydraulic Engineering，Changsha University of Science and Technology，Changsha 410076，China 2 College of Civil Engineering and Architecture，Changsha University of Science and Technology，Changsha 410076，China adxz_168@163.com, b mgbyrh@163.com Keywords: Simple Model; Concrete; Degree Of Hydration; Anns.
So the study of hydration of concrete has important significance on engineering.
Therefore an ANN can be a powerful tool for engineering applications.
Usually, a sigmoidal function, as shown in Fig. 2b, is used as transfer function in civil engineering applications as follows: (6) Where wji is the connection weight from the neuron i in the lower layer to neuron j in the upper layer and an initially small random value, oi is the output of the neuron i, and b is the bias value (Fig. 2c).
