Application Technology
◆All kinds of accelerating agents have adaptability problems to cement. Before use, the cement used in construction must be tested for adaptability to determine the optimal dosage.
◆This product is recommended to reduce 10% water consumption when mixing concrete, and the water will be reduced for accelerating dilution, which is conducive to improving the workability of shotcrete, improving the working surface fluidity, and making the surface of concrete bright and clean and beautiful.
◆feed the mixed concrete into the jet machine and add the accelerator at the nozzle.
◆This product has the best effect on ordinary Portland cement. If other cement is used, it should be tested.
◆cement storage too long or poor construction conditions, must be appropriately increased dosage.
◆operators should take anti-corrosion measures.
Main technical indicators
◆This product is colorless or light yellow liquid. The recommended dosage is 2-6% (by weight), which can be adjusted according to the difference in cement composition.
◆This product has good spray effect and the rebound rate is lower than 15%, which is beneficial to saving raw materials.
Packaging and storage
◆This product is alkaline, should avoid and acid material mixed storage, use.
◆Store in a dry and ventilated place. The product is valid for 90 days and can continue to be used after passing the concrete test.
◆This product is packed in iron drum (plastic drum), 250kg per drum or agreement packing.
