Calcium silicate modular masonry units are a type of masonry product that’s manufactured using a specific process. Instead of being naturally occurring, these units are made by combining lime and silica-based sand. The mixture is thoroughly mixed, ensuring that the lime and silica are well distributed. Once the mixture is ready, it’s then pressed into modular-sized units using high pressure. This process helps in creating uniformity in the shape and size of the units. After the units are formed, they’re subjected to high-pressure steam in an autoclave. This steam treatment is crucial as it helps to enhance the properties of the units, including creating a uniformly fine-grained texture. The result is a high-quality masonry unit that’s durable and suitable for various construction purposes.

After the bricks are molded, they’re left to dry and harden for a specific period of time. Once they’ve fully cured, they’re fired in a kiln at a high temperature until they reach their desired strength and durability. The process of manufacturing calcium silicate bricks involves precise measurements and careful handling to ensure the bricks are of high quality.
How Do You Make Calcium Silicate Bricks?
After molding the bricks, they’re then placed in a curing chamber where they’re subjected to high temperature and humidity conditions. This curing process allows for the formation of strong calcium silicate bonds, resulting in durable and long-lasting bricks.
Once the curing process is complete, the bricks are then dried in a kiln to further strengthen them and remove any excess moisture. This ensures that the bricks are fully hardened and capable of withstanding the rigors of construction and usage.
After drying, the bricks may be subjected to additional treatments such as sanding or painting to enhance their appearance and protective qualities. This can help to prevent water penetration and prolong the lifespan of the bricks.
The final step in the manufacturing process is quality control. Each brick is inspected to ensure that it meets the required specifications and standards. This includes checking for any cracks, imperfections, or unevenness in the surface and ensuring that the bricks have the desired strength and density.
Overall, the manufacturing of calcium silicate bricks involves carefully controlled processes and precise proportions of materials to produce high-quality and durable building materials.
Calcium silicate bricks have impressive properties that contribute to their strength and durability. These bricks exhibit a high compressive strength of 25.31 MPa, meaning they can withstand significant pressure without cracking or deteriorating. Additionally, their water absorption rate of 14.13% after 24 hours of immersion showcases their ability to resist moisture, reducing the risk of damage or deterioration over time.
What Is the Strength of Calcium Silicate Bricks?
Calcium silicate bricks are known for their exceptional strength and durability. One of the key properties of these bricks is their high compressive strength. Compressive strength refers to the ability of a material to withstand pressure or squeezing forces without breaking or crumbling. In case of calcium silicate bricks, their compressive strength is measured at an impressive 25.31 MPa.
Whether it’s for constructing walls, pillars, or foundations, these bricks provide reliable support and stability.
Another important property of calcium silicate bricks is their low water absorption. After 24 hours of immersion in water, these bricks only absorb around 14.13% of their weight in water. This low water absorption rate is crucial for preventing the bricks from deteriorating due to moisture damage. It also helps to maintain the structural integrity of the bricks, ensuring their long-term durability.
Additionally, calcium silicate bricks are known for their excellent fire resistance. They’ve a high melting point and don’t release toxic gases when exposed to fire. This property makes them ideal for constructing fire-resistant walls and barriers, enhancing the safety of buildings. Moreover, their fire resistance also contributes to the overall strength and durability of the bricks, as they can withstand extreme temperatures without structural damage.
These properties make them a reliable choice for load-bearing structures, providing stability and durability.
Comparison of Calcium Silicate Bricks With Other Types of Bricks in Terms of Strength
Calcium silicate bricks can be compared to other types of bricks, such as clay bricks or concrete bricks, in terms of their strength. Strength refers to the ability of the bricks to withstand external pressure or loads without breaking or collapsing.
Calcium silicate bricks are known for their high compressive strength, which is their ability to resist crushing forces. They’ve a dense structure and are made from a mixture of sand, lime, and reinforcing fibers. This composition contributes to their robustness and durability, making them suitable for various construction applications.
Compared to clay bricks, which are made from natural clay and undergo a firing process, calcium silicate bricks tend to have better strength properties. They’ve a higher compressive strength and are less likely to crack under heavy loads.
Concrete bricks, on the other hand, are made from a mixture of cement, sand, and aggregate. They’re known for their high compressive strength and durability. While calcium silicate bricks may not match the strength of concrete bricks, they still offer satisfactory strength levels for most construction purposes.
In summary, calcium silicate bricks exhibit impressive strength characteristics when compared to other types of bricks. Their high compressive strength and sturdy composition make them a valuable option for construction projects.
Calcium silicate blocks, also known as molded calcium silicate insulation, are a commonly used form of high-temperature insulation in industrial settings.
