Description YL-15 is naphthalene-based non-corrosive, non-chlorine compound antifreeze admixture which compounded with water-reducing, early-strength, reducing the freezing point, preventing freezing damage etc. ingredients, powder, it has early-strength, water-reducing, air-entraining, anticorrosion etc. functions. It is mixed to the concrete according to the request, can obviously improve the configuration of the capillary pores and reduce free-water and the freezing point of the concrete effectively. And it can accelerate cement hydration and concrete hardening under the low temperature condition, enhance the early strength greatly and make the strong more and more by time, is ideal admixture for construction in winter. Uses YL-15 is suitable for the winter construction (in ambient temperatures ranging from -5 degree to -20 degree) of common concrete, pumping concrete, large volume concrete and ready mixed concrete. Advantage YL-15 is a new generation of high efficient anti-freezing admixture. Small dosage, completely water soluble, low alkali, apparent reducing effect on the alkali-aggregate reaction. It can improve the workability, pumping properties and early strength of the concrete. YL-15 is suitable for concrete and precast below C50 but also the concrete above C50 with a addition of our high range water reducing admixture.

What should you know about our Concrete mixer, Tank walls thickness. The container body is made by pressing of steel up to 2 mm thick, which let us to obtain a tank with a thickness of 1.5 mm even in the thinnest places. Powder coating based on weather-resistant polyester paint is for external work in severe climatic and operational conditions. Power supply mode is 220V / 50Hz and that means you can use it in normal conditions of the household network. Glass-filled polyamide Crown. In contradistinction to brittle iron, the elastic properties of polyamide give greater resistance to abrasive fractions of concrete mixtures. This ensures a greater life of the polyamide crown compared to cast iron. The whole construction of the cast iron crown is very difficult to replace, even if the crown is not welded to the hull (as is the case for most Chinese concrete mixers). For the same reason the cast-iron crown is an almost non-transportable part and therefore it is very difficult to meet it in the service centers. Polyamide crown is very easy to replace directly in the workplace, not even entirely, but in separate sections: it consists of 4 sections, each of them can be easily replaced without affecting the others. One more big plus is the low noise level of the polyamide crowns. The articulation of the drive shaft with a large pinion with a key. In contradistinction to other brands that use the flattening for spinning, there is no risk of pinching and twisting the pinion on the shaft even at maximum loads in the keyed joint. Toothed belt drive of wide cross section provides the transfer of torque without slipping at any load at different stages of belt wear. Constancy of geometric dimensions gives high accuracy and stability of both linear and angular positioning. Minimal vibration and no jerking at the moments of on-off let you to ensure the belt maximum lifetime. 7 levels of fixing the handle of the concrete mixer. Foot mode fixing the drum releases your hands for convenient unloading and dispensing of the mix. Blades fastening to the body with bolts In contradistinction to the welded joints of the blades, the bolted blades do not break off from the accompanying permanent vibrations and if it is necessary they could be also simply replaced "in the field.

Rose oils are extracted from the Rosa damascena (Bulgarian) and Rosa centifolia (Moroccan) also known as 'rose de mai'. Rose Otto is the essential oil steam distilled from fresh roses. Rose concrete a solvent extraction of fresh roses. Rose absolute is extracted from the rose concrete using alcohol. Rose Otto is distilled from the Bulgarian rose or Rosa damscena. The Otto is an almost clear pale yellow liquid. When it is very cold it solidifies but it is easily warmed to liquid again. Rose Otto smells rich, floral, warm and spicy with honey undertones. The smell of fresh roses becomes more apparent at when the Otto is diluted. Rose Otto is the most expensive extract of roses. Rose concrete from Rosa damscena is a deep orange colored mass of a jam-like consistency, can be greenish yellow.
