KRS plank – a fibre cement plank for traditional architecture
KRS fiber cement plank is a unique fibre cement composite of natural fibres bonded tightly in a high-grade silicate structure. This autoclaved wood-grain siding acquires impressive toughness, yet remains flexible and dimensionally stable. It is cellulose cement plank that contains absolutely NO asbestos fibre, no fibre glass fibers nor formaldehyde.
KRS Plank. Anything Else is Just a Façade.
KRS fiber cement Plank is simple to handle and easy to install and is therefore suitable even for the Do-It-Yourself (DIY) segment. KRS plank is a fibre cement siding and is fire resistant to A2-s1, d0 and made in accordance to EN12467.
KRS fiber cement Plank is also water resistant, insect and rot resistant and therefore requires very little maintenance. It is the perfect fiber cement siding for any house that needs a simple, yet durable cladding material. KRS Plank comes in several sizes and textures to match your housing needs, making it easy to select your desired interior/exterior cladding materials.
It is also a perfect solution for all wood-cladding houses that face a constant threat from termites and water damage since it possesses excellent properties of pest resistance, impact strength and water/moisture resistance. It comes in several sizes and textures and primed planks can be coated before or after installation (double coating) with optional acrylic paint.

Krs cladding board – a fibre cement board with high impact strength and moisture and fire resistant properties
Krs fiber cement board is the perfect choice for building board applications such as wall cladding, wall partitioning and decorative walling. The types of buildings that are suitable for krs board applications are residential, commercial and industrial buildings as well as schools and hospitals; especially where speedy construction, cleanliness and hygiene is of high importance.
Benefits of krs fibre cement board:
weather resistant
immune to water damage
fire resistant
provides sound insulation
shatter resistant
low shrinkage
flexible
high degree of workability
termite resistant
Matching the demands of modern applications
Fiber cement board is a non-asbestos fibre-cement product composed of portland cement, cellulose fibre and refined sand.
Using a special manufacturing process called autoclave, fiber cement board acquires the strength, durability of cement and easy workability of wood as well as dimensional stability.
A non-combustible multi-purpose application fibre-cement flat board, fiber cement board comes with various thicknesses which are suitable for various applications; ceiling, wall, and floor.
It can be used for both exterior and interior applications. Krs boards can perfectly be calibrated and then laminated or coated with other materials, such as eg. Wood veneer.

he horizontal cement silo, also called portable cement silo, is a new type of bulk cement storage equipment. The bottom is supported by multiple brackets. The horizontal cement silo is equipped with a cement discharge port and a screw conveyor at the bottom, which can be easily discharged and conveyed.
Compared with the traditional vertical cement silo, the horizontal cement silo has low requirements on the foundation, which can be directly placed on the ground, and can be easily transported by truck or flatbed without disassembly.
Due to its unique advantages, horizontal cement silos are widely used in various mobile concrete mixing plants, foundation-free concrete mixing plants and other temporary concrete mixing plants.
The portable cement silo is of simple structure, reliable operation and unique modular installation, which can dynamically combine multiple storage units together to meet the storage requirements for cement and fly ash.
The each raw material storage tank of portable cement silo is is composed of brackets, lower cone, silo body, feeding pipe, climbing ladder, and safety valve; among them, dust collector (ordinary dust collector, electronic vibration dust collector, pulse dust collector) and level indicator can be freely selected by the customer. The horizontal cement silo does not need installation.
We provide the cement silo capacity from 50T to 500T. Cement silos are a necessary device in the production of concrete. The silo is designed for storing cement, fly ash, coal ash, lime, etc powder material. It is bolted type silo, easy to transport and install. It is manufactured divided into 3 parts, namely the top cover of the silo, the middle section, and the cone part. Each part is of piece production, all pieces of manufactured standard film.
Cement silo Features and advantages:
Perfect sealing
Screw connection
Waterproof, moisture-proof, anti-corrosion
Convenient installation Safe and reliable
The cement silo is usually matched with a cement screw conveyor, widely used for concrete batching plants. We supply factory-price cement silo, cement screw conveyor, and a complete set concrete batching plant for you. Welcome to contact us!

The improvement of the performance of low cement casting material is actually the application of micro powder technology.
There is a gap between the stability of low cement castable and that of laboratory castable.Low cement castable easy to occur problems are: 1, poor construction performance, poor liquidity;2. The hardening speed varies greatly, and there is quick setting or non-setting;3, easy to burst in baking;4. Abscission occurs;5. Low strength and poor wear resistance.These are caused by refractory castable products abnormal damage and other quality problems.
Low cement refractory castable itself in addition to wear resistance, refractory aggregate, is used with good raw materials fine powder and ultrafine powder, cement and admixture, etc., through adjusting the proportion of each component, improve the high temperature performance of castable, thereby improve the strength of refractory castable.
Low cement castable key construction, should pay attention to is: (1) do not arbitrarily increase the water content of refractory castable, (2) mold support set too high, leading to castable water content is too large and vibration compaction;(3) No mold shall be set during lining construction of feeding pipe, and castable material shall be manually daubed;(4) In order to save the mold, the maintenance is less than 48 h to remove the mold, resulting in the casting cracking or internal damage;(5) The material, shape, size, welding quality, quantity, anti-expansion treatment and unreasonable expansion joints of the anchoring parts;Do not follow the operational sequence of dry stirring, wet stirring and feeding, directly mix the dry and wet materials, resulting in the castable is not fully mixed evenly, part of the material is not wetted by water, making the castable has no strength.
There are also key water issues, to use tap water, to avoid the introduction of acid and base impurities, gradually add, in order to make the dispersant in the powder to play a full role.Excessive water addition will directly lead to a significant decline in the strength of refractory castable construction, and in the field construction the water addition tends to exceed the degree of artesification.The pouring body itself is easy to appear when the ambient temperature rises rapidly, the baking burst, resulting in large area of damage.Once the temperature of the castable itself is below 5 â??, the castable will still have no strength even after curing for 24 hours.The construction and maintenance shall be carried out in strict accordance with the 48-hour mold removal mechanism. In dry areas, water and wet maintenance shall be carried out; in cold areas, airtight heating maintenance shall be realized within 48-hour maintenance to ensure the maintenance temperature.
In a word, if the above points can be achieved step by step in accordance with the requirements, it will certainly improve the performance of low cement casting.
High Alumina Refractory Cement is manufactured from Calcined Alumina and high purity lime. It is used as a binder for all types of castable refractories. Ashapura offers two ranges; HARB 50 and HARB 70 with minimum alumina content of 50% and 70% respectively.
