Cracking make the concrete and the RC structures vulnerable to external effects and accelerates the ageing process resulting in the reduction of the mechanical resistance of the structure.
All the data obtained were analyzed statistically using Design Expert 7.0 software to establish the possible relationship between variables and parameters adopted.
For this purpose, the response surface methodology (RSM) model was utilized to confirm the predicted data to the actual data obtained.
By using historical data analysis, a three-dimensional graph can be produced, and the equation generated.
The plot also shows adequate agreement between real data and model results.

This article uses large amounts of data as evidence to demonstrate the present state of the problems of great public interest, such as shortage of resources, the widening gap between the rich and the poor, employment and medical problems, with the goal of deepening people's understanding and promoting resolution of these problems.
Supported by data, this article strives to show the present state of these problems, so as to improve people’s sense of crisis and create a favorable ideological atmosphere for sustainable development.
Data show that in 2009 there were nearly 7.1 million college students who were in need of jobs, and due to the impact of the crisis, about 20 million migrant workers all over the country lost their jobs.
It is estimated that China’s economic growth rate in 2011 will slow down to 7.5%, which in turn would lead to reduction of new jobs.

Comparison with the data of the IR, the combination of carboxyl is chelating with Ti atoms.
P.A.Venz, J.T.Kloprogge and R.L.Frost studied that Elimination of carboxylic acid groups is increasingly favorable with longer chain length, but the modifying groups also become more difficult to protonate [6].Qunji Xue synthesized the 2-ethyl hexoic acid (EHA) surface-modified TiO2 nanopa- rticle use sol-gel method and studied the friction-reduction and antiwear behaviors as an oil additive in liquid paraffin [7].
