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.

One rig for engineering industry, the wider applications, suitable for use in a variety of areas, but most major application is in the construction field, and simultaneously occupy an important position, but also the infrastructure necessary for the const

Like with ordinary concrete construction, the steel can be poured directly into the concrete design position, do not have to set aside holes, wear bars, grouting, simplifying the construction process, due to the effective pre-unbonded prestressed concret
