Anti-crack connectors - Biobrasa

Anti-crack connectors, also known as reinforcement connectors or joint connectors, are devices used in civil construction to improve the strength and durability of concrete structures. They are designed to prevent the formation of cracks and to reinforce the joints between different structural elements. Here are some common types of anti-crack connectors and their applications:

Metal Mesh Connectors:
Description: These are steel meshes that are embedded in the concrete to reinforce the structure.
Application: Used in slabs, floors and other flat surfaces to prevent cracks due to concrete contraction.

Fiber Connectors:
Description: Steel, polypropylene or other material fibers are added to the concrete during mixing.
Application: They help distribute internal stresses in the concrete, reducing the formation of cracks.

Joint Connectors:
Description: Metal or plastic devices that are installed in expansion or contraction joints.
Application: Used to allow controlled movement of concrete structures, preventing cracking at joints.

Anchorage Connectors:

Description: Metal devices that are fixed to concrete surfaces to anchor new layers of concrete or other materials.

Application: Used in repairs, renovations and additions to concrete structures to ensure a strong and durable bond.

Edge Reinforcement Connectors:

Description: Metal devices that are installed at the edges of slabs or other concrete structures.

Application: Help prevent cracking at edges, which are areas particularly susceptible to stress.

Corner Reinforcement Connectors:

Description: Metal devices that are installed at the corners of concrete structures.

Application: Help prevent cracking at corners, which are areas of high stress.

Benefits of Anti-Crack Connectors

Improved Durability: Help extend the life of concrete structures by preventing cracking.

Reduced Maintenance: Reduces the need for frequent repairs due to cracks.
Improved Aesthetics: Maintains the appearance of concrete structures by preventing visible cracks.
Safety: Helps ensure structural integrity, especially in areas subject to movement or stress.
Considerations

Design and Installation: It is important that anti-crack connectors are designed and installed correctly to ensure their effectiveness.
Material Quality: Selecting high-quality materials is crucial to the durability and effectiveness of the connectors.
Compatibility: Connectors must be compatible with the type of concrete and the specific environmental conditions of the project.
Anti-crack connectors are a valuable tool in the construction industry, helping to ensure the integrity and longevity of concrete structures.

Rice husk, also known as rice bran, is a byproduct of rice milling. It is mainly composed of the outer layer of the rice grain, which is removed during the polishing process to produce white rice. Rice husk has several applications and benefits, including:

Fuel: Rice husk is often used as fuel in boilers to generate heat and power. It has a high calorific value and is a renewable energy source.

Compost and Soil Improvement: Rice husk can be composted and used as organic fertilizer to improve soil fertility. It helps increase organic matter and water retention in the soil.

Growing Substrate: Rice husk can be used as a substrate for growing mushrooms and other plants.

Animal Feed: Although pure rice husk is not suitable for animal feed due to its low digestibility, it can be processed and mixed with other ingredients to produce animal feed.

Building Materials: Rice husk can be used in the production of building materials such as eco-bricks and building panels.

Water Filtration: Carbonized rice husk can be used as a filtration material to purify water, removing contaminants and heavy metals.

Silicon Production: Rice husk is rich in silica, which can be extracted and used in the production of silicon, an important material for the semiconductor industry and other technological applications.

Rice husk is a valuable resource that can be used in many ways, contributing to sustainability and the circular economy.
