Hydro clay ball

Hydro Clay Balls are a great growing medium substrate for hydroponics consisting of spheres of expanded clay, which provide inert structural support for plant roots in hydroponic and aquaponics systems.

The clay pebbles are manufactured from special types of clay that have a low soluble salt content. Because of this, they are particularly suited for use in closed hydroponic cultivation systems. They have both high porosity and high air content which stimulate the development of strong roots that grip the substrate well.

General Directions For Use:

General rule of thumb to follow in irrigating plants is to apply 10-15% more water than the container will hold. Frequency of application will depend upon plant size and grow room temperature, but will vary from one 15 minute feed every hour while the lights are on during the first weeks of growth then one 15 minute feed every two hours starting several minutes before the lamps have been turned on. Only water the plants in the day period.

Leca clay balls expanded clay pebbles characteristic.

LECA clay ball density

Leca clay balls expanded clay pebbles 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 inside, which has the characteristics of low density, low thermal conductivity and high strength. In the refractory industry, leca clay balls expanded clay pebbless are mainly used as aggregates for heat-insulating refractory materials. The bulk density of the leca clay balls expanded clay pebbles itself is less than 1100kg/m3, generally 300-900kg/m3. The density of concrete made of leca clay balls expanded clay pebbless as aggregate is 1100-1800kg/m3.

Leca clay ball concrete compressive strength

The corresponding compressive strength of leca clay ball concrete is 30.5-40.0Mpa. It is hard on the outside, but there are many micropores inside. These micropores give leca clay balls  light weight properties. The concrete density of No. 200 fly ash leca clay balls expanded clay pebbles is about 1600kg/m3. At present, the sand of my country’s leca clay balls expanded clay pebbless is mainly used for petroleum proppant, and it is also one of the sand varieties of leca currently in demand, also known as sand for oil fracturing proppant leca. 

Advantage of clay aggregate concrete

The concrete of ordinary fly clay ball or the clay aggregate blocks integrate heat preservation, earthquake resistance, frost resistance, fire resistance and other properties. Especially the fire resistance is more than 4 times that of ordinary concrete. For the same refractory period, the thickness of the concrete plate of the expanded clay pebbles is 20% thinner than that of ordinary concrete.

clay aggregate blocks integrate heat preservation.

In addition, expanded clay pebbless can also be used to prepare refractory concrete with a refractoriness below 1200°C. At a high temperature of 650 ° C, the concrete of expanded clay pebbles can maintain 85% of the strength at room temperature. Ordinary concrete can only maintain 35% to 75% of its strength at room temperature.

Density and fluidization rate factors of clay pebbles/ leca blocks

Concrete is generally used instead of gravel and pebbles. The solid waste of leca blocks, varies in color, usually black, and the matte surface is smooth. The internal structure is fine honeycomb.

Leca blocks 3 types

According to the density, they are divided into three types: general density type, ultra-light density type, and optical density type. It has high strength and is used for insulating concrete or reinforced concrete structures. The price is more reasonable. 

Leca bolcks is economic

High-quality leca blocks cost affects project investment and operating costs. Although cheap natural materials are used for filter media, investment can be saved, but the properties such as density and fluidization rate are not suitable for backwashing, which may increase energy consumption and affect operating costs.

Some synthetic filter materials have good performance but are costly, price is too high. Therefore, the choice should take into account both performance and price. 

The nitrification function of the biological aerated filter is the best when the particle size is 2-4mm.

At present, the particle size of the filter material commonly used in the biological aerated filter is 3-6mm, and the thickness of the filter layer is 3-4mm.

Leca blocks benefits

 The clay pebbles/ leca is a kind of light artificial particle with unique performance, which is widely used in the preparation of high-rise building structure concrete, roof slope finding, thermal insulation, sewage treatment, landscaping, soilless cultivation and other fields.

It has a proper packing density of the filter material, and the layer voids are evenly distributed, making backwashing easy, with low backwashing consumption, small water consumption, small water head loss, and no material leakage during backwashing.

The high-quality have overcome the shortcomings of backwashing being difficult to control and running out of materials. It adopts good particle size distribution, strong dirt holding capacity and high utilization rate of filter material. The water head increases slowly, the operation period is long, and the water production is large. The concrete of clay pebbles/ leca blocks is better than ordinary concrete in acid, alkali corrosion and frost resistance.

Concrete of clay pebbles/ leca blocks is an excellent building material

For the concrete of No. 250 fly ash clay pebbles/ leca block, the strength loss of 15 freeze-thaw cycles is not more than 2%. In 1976, relevant departments conducted actual measurements on the concrete projects of leca blocks built since 1985. The results showed that no matter whether it was prefabricated or cast-in-place, indoor or outdoor, the steel bars contained in them were not corroded. The depth of carbonization is generally not more than 30 mm, and the strength can continue to grow in the later stage. It can be seen that the concrete of clay pebbles/ leca blocks is an excellent building material and should be vigorously promoted.

Toilet use clay pebbles/ leca backfill steps

Toilets backfill clay pebbles/ leca is a special building material, which is widely used in toilets and places where water is frequently used. 

Bathrooms backfill clay pebbles/ leca has many excellent properties.

First of all, in terms of its weight, it is much lighter than the commonly used construction waste backfills materials. At the same time, it is much more convenient to use and will not cause any pollution or damage to the environment.

Secondly, even its water absorption and dirt absorption ability are also excellent, which virtually ensures the cleanliness of the bathroom environment. In fact, there are many friends around us who are curious when they first learned about the clay pebbles/ leca backfilling in the bathroom.

What are the steps for using clay pebbles/ leca in the backfilling of the bathroom?

First of all, in order to ensure that the water seepage from the upper layer of the waterproof layer will not spread to the surroundings, it is necessary to make waterproof coatings on both sides, both the upper and lower sides, and it must be connected with the wall. The height of the wall should be 40 meters higher than the upper edge of the caisson. cm or more.

Second, use concrete as a partition overhead, and divide the caisson into several 400×400 grids. Many people do not see the importance of such a load-bearing partition. In fact, this measure cannot be ignored. It can prevent the concrete above from falling Otherwise, it may cause the bathroom floor to sink, crack and leak after a few years.

Third, the next step is filling. Fill the moisture-proof ceramic particles into the grid, and don’t press it too tightly, because its function is not load-bearing but sound insulation and filling.

The fourth is to arrange a layer of 30 cm × 30 cm steel mesh composed of steel bars with a diameter of about 10 mm on the grid to ensure the firmness and uniform stress of the clay pebbles/ leca concrete layer.

Finally, the concrete layer is rammed, and the vibrating pump is added for construction, and the fine stone concrete with a thickness of 10 cm is leveled. This layer still needs to be made with a drain slope, and then waterproof materials are made twice, and it is done together with the wall. After it dries up, it needs to be brushed with plain grout to protect it.

In fact, the process of backfilling the bathroom floor with clay pebbles/ leca is not very complicated. As long as some key parts are done, the effect will be achieved. At the same time, clay pebbles/ leca is an environmentally friendly material that can be recycled and reused, and it can also play a role in environmental protection.

Matters needing attention when purchasing clay pebbles/ leca

Need to compare more leca from different suppliers.

First: The quality of the products, this is an important, so for us, generally the clay pebbles/ leca you see is the picture of the sample, the product quality is good, and the size of the specification is not much different, but when you see the bulk cargo, it is different. The size  is uneven, and the surface will be broken when pinched. These are all defective clay pebbles/ leca. At this time, you should compare more manufacturers and choose some powerful product. It is very important for a manufacturer to have perfect inspection and testing.

Check the quality after receiving

Sceond: After purchasing, you need to check the quantity you received is sufficient or not. Some manufacturers ship less than what you want. When your cargo is delivered, pay attention to whether the quantity is enough. This can be avoided.

After sale service

Third: Perfect after-sales service. A perfect after-sales service for building materials, such as building materials, can save you from such trouble when you buy again. A good clay pebbles/ leca company should have perfect after-sales service, so that you can buy with confidence.

Leca quality is the same important as the price

Last: When buying clay pebbles/ leca, you can inquire about several companies and want to make comparisons. Sometimes you get what you pay for, cheap ones are maybe good, but expensive ones must have expensive benefits. We have seen many clients to compare by the pictures, the difference can be seen at a glance. The cheap one will be broken when pinched. If you use that kind of leca for construction, you must be afraid of it, its compressive performance is too poor, and the later renovation and maintenance will not work.
