شرح

Features

1. Alkali-free: It can reduce the risk of alkali-aggregate reaction, reduce the loss of final strength of shotcrete, improve the durability of concrete, and be suitable for permanent support.

2. Accelerated setting: the setting time and strength of shotcrete can meet or exceed the requirements of national standards, which is beneficial to speed up the construction progress.

3. Economical: It replaces the double-layer construction mode of "support first, then lining", reduces the thickness of support, and saves project capital investment.

4. Environmental protection: Shotcrete construction rarely produces dust and provides a good underground working environment. This product is non-corrosive, greatly improving work safety and reducing environmental pollution.

5.The thickness of the sprayed concrete layer at one time is not less than 10cm for the sprayed arch and not less than 15cm for the sprayed side wall. This product can make the shotcrete bond better with the rock surface, reduce the rebound and effectively bond the shotcrete layer.

Instructions

1. Wet spray method: Mix the concrete with water first, then add this product into the compressed air pipeline through the metering pump, and spray it out from the nozzle together with the concrete.

2. Dry spraying method: The concrete is mixed in advance, the product is added into the water through the metering pump, and the water is added into the concrete mixture through the spray nozzle.
