Self Insulation Block Silica Fume

The construction industry is in constant evolution, constantly adopting new materials to enhance the durability, sustainability, and aesthetics of the structures being built. One such material that has gained significant attention in recent years is the self-insulating block, particularly those infused with silica fume. In this article, we’ll delve deep into the world of Self Insulation Block Silica Fume (SIBSF), exploring its composition, properties, uses, and benefits in construction.

Understanding Self Insulation Blocks

Before we jump into the world of SIBSF, it’s vital to understand the basic concept of self-insulating blocks. These are construction materials designed with insulation as a core feature. They are typically made of a variety of materials, including concrete, clay, and other aggregates, which are mixed with insulation materials to achieve high thermal resistance. This inherent insulation property makes these blocks ideal for constructing energy-efficient buildings.

The Emergence of Self Insulation Block Silica Fume (SIBSF)

The combination of self-insulating blocks with silica fume brings together the best of both worlds – the insulative properties of the former and the strength and durability of the latter. The result is a building material with excellent thermal resistance, high strength, and impressive durability.

How is SIBSF Made?

The production of SIBSF begins with the creation of the self-insulating block. This is typically made by mixing cement with a particular aggregate and an insulating material. Once this is done, the silica fume is added to the mix. Given its small particle size, the silica fume disperses evenly throughout the mix, filling up the spaces between the other particles. This results in a dense, strong, and thermally resistant block that is ready for use in construction.

Properties of SIBSF

High Thermal Resistance

The primary feature of SIBSF is its high thermal resistance, also known as its R-value. This property reduces the amount of heat that passes through the block, making it perfect for energy-efficient construction.

Strength and Durability

Silica fume’s addition to the mix significantly enhances the strength and durability of the blocks. The particles of the silica fume fill the voids in the concrete mix, creating a dense and strong block that can resist a variety of stresses.

Environmentally Friendly

Both the self-insulating blocks and silica fume are considered environmentally friendly. The blocks reduce energy consumption, and the silica fume is a byproduct of industrial processes, utilizing a material that would otherwise go to waste.

Applications of SIBSF in Construction

SIBSF can be used in a variety of construction applications. Its high thermal resistance makes it an excellent choice for constructing building envelopes, particularly in climates with significant temperature variations.

Additionally, due to its strength and durability, SIBSF can be used in load-bearing walls and structures, reducing the need for additional materials. Its dense nature also makes it an excellent sound insulator, making it suitable for construction in noisy environments.

The Production of SIBSF

The production of SIBSF is a meticulous process that combines the benefits of self-insulation blocks with the performance-enhancing properties of silica fume. A high-performance microsilica hollow block is used as the shell. This shell is then filled with lightweight thermal insulation materials, such as foam micro silica fume powder or polystyrene foam. The microsilica density and heat preservation material are injection molded into the block, forming a silica fume block with building envelope and heat insulation functions. This intricate process results in a block with excellent comprehensive performance, including lightweight, high strength, thermal insulation, and sound-absorbing insulation. Furthermore, the construction process is simple and cost-effective, making SIBSF a popular choice in the construction industry​.

Advantages of SIBSF

Energy Efficiency

One of the key advantages of SIBSF is its superior energy efficiency. The thermal insulating properties of the blocks significantly reduce the energy required for heating or cooling a building, thereby reducing the building’s overall carbon footprint.

Strength and Durability

The addition of silica fume to the blocks not only enhances their thermal insulation properties but also significantly increases their strength and durability. This makes SIBSF ideal for constructing buildings that need to withstand various stresses and strains over a long period of time.


Due to their easy construction process and the fact that they combine the features of both insulation and structure in one block, SIBSF can be a more cost-effective choice compared to traditional building materials. These factors can significantly reduce both construction time and costs, making SIBSF an attractive choice for budget-conscious projects.


Both self-insulating blocks and silica fume are environmentally friendly materials. The energy efficiency of the blocks contributes to lower CO2 emissions, and silica fume is a byproduct of the silicon and ferrosilicon alloy production process, which would otherwise be wasted. Thus, the use of SIBSF supports sustainable construction practices.


The Self Insulation Block Silica Fume (SIBSF) is more than just a building material; it’s a game-changer in the world of construction. Its unique combination of properties – energy efficiency, strength, durability, cost-effectiveness, and environmental friendliness – makes it a highly attractive choice for modern construction projects. As the construction industry continues to evolve, materials like SIBSF will likely become increasingly prevalent, leading the way towards more sustainable and efficient building practices.
