摘      要：In this study,the workability of cement-based grouts containing n-TiO 2 nanoparticles and fly ash has been investigated *** characteristic quantities(including,but not limited to,the marsh cone flow time,the mini slump spreading diameter and the plate cohesion meter value)have been measured for different percentages of these *** use of fly ash as a mineral additive has been found to result in improvements in terms of workability behavior as ***,if nano titanium oxide is also used,an improvement can be obtained regarding the bleeding values for the cement-based grout *** such experimental data,a multi-layer perceptron artificial neural network model has been developed(5 neurons in the hidden layer of the network model have been developed using a total of 42 experimental data).70%of the data employed in this model have been used for training,15%for validation and 15%for the test *** results demonstrate that the artificial neural network model can predict Marsh cone flow time,mini slump spreading diameter and plate cohesion meter values with an average error of 0.15%.
