Within the Drytech range, products with sol-gel technology without cement that allow easy drying, ALFRAN has developed a concrete applicable with the GUNMIX system, high efficiency dry projection, which guarantees excellent behaviors against abrasion but with a high speed installation much higher than the vibrocasted. This product is the ideal solution in areas with high wear due to the passage of gases with suspended particles or areas of high corrosion with great difficulty in formwork. It thus becomes a great alternative in unexpected shutdowns that require entry into service of the equipments with a lot of haste.
