Therefore, the developed data acquisition system satisfies the demand of precisely acquiring information related to friction wear testing of experimental materials.
Introduction During studying friction wear mechanism of materials, friction wear testing machine is essential to ascertain the composite tribological properties used to evaluate the materials performance [1,2].
In addition, displaying and saving the acquired information related to tribological properties of materials are essential to further studies.
Property parameters involving experimental materials will vary when changing the experiment conditions, as adjusting rotate speed and normal pressure.

Considering ancient monuments and historical buildings, it seems that these mortars have proved to be durable and reliable materials.
This work is included in a study intending to determine key factors to the durability of these ancient materials in presence of water.
Its kinetics of formation and development are influenced by environment but also by raw materials, strengthening the ancient masonry [9-12].
