20mm Concrete Spacer

Concrete Spacers are typically made from a mix of Ordinary Portland Cement (OPC), Ground Granulated Blast-furnace Slag (GBS), Ground Granulated Blast-furnace Slag (GGBS), fibres, and various additives. This composition provides strength and durability to the spacers.

The compressive strength of Concrete Spacers is not less than M60, indicating they can withstand significant loads without failing. This makes them suitable for heavy reinforcement applications such as rafts and footings.

The water absorption rate of Concrete Spacers is less than 5%, which minimizes the risk of degradation and ensures longevity in various environmental conditions. Low water absorption helps maintain the integrity of the concrete structure over time.

Yes, they are designed with outstanding chemical and physical resistance, making them suitable for use in harsh environments. Their properties ensure that they perform well even under challenging conditions.

The deflection under load for Concrete Spacers is less than 1mm, which indicates minimal deformation when subjected to heavy loads. This ensures that they maintain their structural integrity during use.

Concrete spacers are usually made from the same mix design as the concrete they are used with, ensuring compatibility in strength and durability. This helps to prevent any potential issues related to differing material properties.

By ensuring that rebar is properly positioned, concrete spacers help maintain the structural integrity of concrete elements. This reduces the risk of structural failure, which can lead to safety hazards during and after construction.

Yes, concrete spacers can be used in a variety of applications, including foundations, slabs, and walls. However, the design and specifications should always be followed to ensure optimal performance.

Concrete spacers are typically placed on the ground or formwork before the rebar is positioned. They should be evenly distributed to maintain the required cover and ensure that the rebar remains in place during the pouring of concrete.

Maintaining the correct cover with spacers is crucial for protecting the rebar from corrosion and ensuring that the concrete can effectively bond with the steel. This cover also helps to enhance the overall durability and lifespan of the concrete structure.

Yes, concrete spacers must comply with relevant construction standards and codes, which dictate their design, material properties, and installation practices. Adhering to these standards ensures that the spacers perform effectively in their intended applications.
