• Fresh and hardened concrete tests for the self-compacting concrete used showed that the concrete fulfilled the requirements for balcony repairing. • The results of slab frost resistance tests show the scaling and flexural strength change of self-compacting concrete was very small after 300 cycles and the changes in ultrasound transmission time were small, so there is no sign of inner

Our leading products are steel strands for prestressed concrete structures. These are popular for use in the construction of roads, bridges, high rise buildings, and even water conservancy projects. Stainless Steel Product Base
To study seismic behavior of prestressed fabried concrete frame structure, the experiments on the concrete frame under dynamic loading and low reversed cyclic loading were carried out. The single-span three-story prestressed fabried concrete frame can accurately represent the load-carrying capability and the failure mechanism of multistory frame.
