It is true in the article titled "Shaking Table Tests On A Recycled Concrete Block Masonry Building", Wang, Changqing, and Jianzhuang Xiao that most of the houses have been constructed using varied materials which has resulted to persistent and disordered exploitation and the exaction of natural resources viz a viz natural gravel and natural sand in China. Actually, there has been high demolition and construction waste for instance waste block, tiles and concrete which had been produced annually and have reached their life time. The results of high demolition and construction are attributed to the natural disasters like earthquakes. From the article it is true that environment conservation and preservation is needed and it is out of effective resource utilization and recycling the C and D that all that can be achieved. To proof that effectively utilizing the construction and demolition waste as the best recycled aggregate for any material for a building. So as to add some sense on the technology, there is need to do some experiments globally in support of the technology.

In short, the article answers the question how the concrete masonry material works in earthquakes. The model which was used to gauge and come up with material will help in reducing the disaster in this case the earthquake. A model of masonry blocks having a tie column, ring beam and a cast-in-place slab system which was designed from the recycled aggregate concrete (RAC). This model was put on the test on a MTS shaking table at the state key Laboratory for the disaster reduction in Civil Engineering, Tongji University, Shanghai, China. The designed and the manufacturing of the model was the talk of the day at the University. The design of the model proved that the model can work best in case of any earthquake. Wang et al. 2015 argues that, “The natural frequency, equivalent stiffness of the structure, the structural damping ratio, the acceleration response, the seismic force response, the displacement response, the base shear response and the structural fragility etc. were analyzed and discussed.” The author says, “The test results demonstrate that the RAC block masonry structure confined by the 'tie column + ring beam' system is a good solution to withstand earthquakes. The storey drift ratio and the overall behavior meet the requirements of Chinese design code. Generally, the RAC block masonry structure bounded by the 'tie column + ring beam' system with proper design exhibits good seismic behavior and can resist the earthquake attacks under different seismic levels in this study.” This demonstrates how the concrete masonry material works in earthquakes.

In conclusion, the key properties of concrete blocks are useful in the prevention and deterring of earthquakes which is one the key problem facing the world. These properties need to be investigated and reports designed in support of the functions of concrete blocks as to mitigation of earthquakes.
