GZ-5 shotcrete machine/ gunite machine/ dry-mix concrete spraying machine is widely used for tunnel construction.

Gaode Equipment delivered prestressed strand to South America on October 14th.

In ordinary reinforced concrete structure, due to the low concrete ultimate tensile strain, in the use of loads, component of steel strain considerably more than the ultimate tensile strain of concrete.

In the use of prestressed concrete, should pay attention to the following situation, to ensure the safety of both parties.

1 good vibration resistance, foam concrete block.As a result of the foam concrete block is very light, greatly reduce the building self-respect, higher than that of clay brick building the two seismic level

Grouting pump performance, the quality of grouting engineering safety, quality, efficiency, plays a decisive role.The selection of grouting pump with blindness and randomness, probably spent a larger price and failed to achieve the desired effect

Foam cement used in concrete can not be arbitrarily blending different levels, in addition to the production of foam concrete for cement stability is also required, mainly as follows:

In the use of prestressed, it should pay attention to the following conditions in order to ensure the safety of both sides.
