The mechanical resistance, water absorption, porosity and problems of dimensional variation due to shrinkage prove to be primordial and of great importance for evaluating of the durability of self-compacting concrete (SCC) based on recycled coarse aggregates. In part II of this study, ordinary gravel is partially replaced (50 and 100%) by recycled gravel for the preparation of eight compositions, with a constant water/binder ratio (W/B) = 0.4 and a binder dosage equal to 475 kg/m 3 . Physical and mechanical properties of SCC are evaluated through a number of laboratory tests. According to the findings of this study, the water absorption and porosity of SCC with recycled coarse aggregates are generally high, and can reach up to double that of the control SCC. Shrinkage of SCC is significant, however mechanical resistance is low compared to SCC with oridinary gravel. The results also suggest that, using binary mixtures can significantly improve the durability of SCC.

According to the properties of concrete, it is necessary to upgrade this material. In areas such as construction. Concrete has many pores and increases the amount of water penetration. One of the ways to make waterproof concrete is to use crystal and zycosil technology. The details of this technology are expressed in the form of scientific texts and images. In this article, a descriptive-analytical research method has been used. The purpose of study is to provide methods to prevent water from entering the concrete. This issue increases the architectural quality of concrete buildings. It can also be concluded that using waterproof concrete with this technology is important. This material prevents the building from damaging chemical reactions caused by water penetration. Finally, this material increases the quality of the building in execution.
