Ceramsite

Ceramsite is a kind of lightweight aggregate produced by foaming in a rotary kiln.It has a spherical shape, a smooth and hard surface, and a honeycomb shape inside. It has the characteristics of low density, low thermal conductivity and high strength.In the refractory industry, ceramsite is mainly used as an aggregate for insulating refractories.

Ceramsite has a certain degree of mechanical strength, strong ability of water absorption, ventilation and fertilizer retention.Small particles are piled together to form many cavities, which are ventilated and dilute, and will not be compacted.There is no dust in the dry state, it will not disintegrate after being soaked in water, and it will not produce muddy water.

Most of the appearance features of ceramsite are round or oval spheres, but there are also some imitation crushed stone ceramsites that are not round or elliptical spheres, but are irregularly crushed.The shape of ceramsite varies depending on the process.Its surface is a hard shell. This shell is ceramic or enamel, which has the function of water and gas retention and gives the ceramsite high strength.

Ceramsite has excellent properties, such as low density, high cylinder compressive strength, high porosity, high softening coefficient, good frost resistance, and excellent alkali-resistant aggregate reactivity.Especially due to the low density of the ceramsite, the internal porous, uniform shape and composition, and certain strength and firmness, it has the multifunctional characteristics of light weight, corrosion resistance, frost resistance, earthquake resistance and good insulation.Using these excellent properties of ceramsite, it can be widely used in building materials, horticulture, food and beverage, refractory insulation materials, chemical industry, petroleum and other sectors. The application fields are becoming wider and wider and continue to expand.

The reason why ceramsite has developed rapidly all over the world is because it has many excellent properties that other materials do not have. This excellent performance makes it have a role that other materials cannot replace.These excellent properties have the following aspects:

1. Heat preservation and heat insulation

2. Excellent fire resistance

3. Good shock resistance

4. Low water absorption, good frost resistance and durability

5. Excellent impermeability

6, anti-alkali

7. Strong adaptability

So what are its uses?

Ceramsite concrete has been widely used in various types of pre-components and cast-in-situ concrete projects in industrial and civil buildings (such as prestressed and non-prestressed, load-bearing structures or enclosures, heat insulation or impermeability, static load or dynamic Contained).Ceramsite can also be used in other construction materials such as pipe insulation, furnace body insulation, cold insulation, sound insulation and sound absorption; it can also be used as soilless bed material and water filtration material in agriculture and gardens.
