Why Concrete?
Concrete spacers are used for quality concrete construction. It’s that simple.
Plastic and concrete are two different materials. Plastics in the majority are usually synthetic, most commonly derived from petrochemicals with man made plastic invented circa 1856. Plastic was originally intended to be used to make reusable maleable products, unlike the majority of plastics today which are throw away and typically end up in landfill or our oceans.
Concrete like materials have been in use since 6500BC and in building concrete structures since circa 700BC.
At CONC we’ve been to numerous building sites and know how harsh and know how harsh an environment they can be. Rest assured you can walk and drive all over CONC product without having to worry about it being crushed. The manufactured compressive strength of our concrete spacers is great than 50MPA. We can achieve higher MPA ratings for specific order requirements.
Concrete spacers have a textured surface allowing the surrounding concrete pour to bind to the exterior face, reducing the chance of sinking and providing a stronger pour. Unlike plastic which can create weak spots. Due to the shape of CONC's concrete spacers you can be assured that the steel rebar is completely encased.
When concrete is poured over steel rebar, the intention is that the concrete bonds strongly to the surface of the steel so that stresses are transferred efficiently from the concrete to the rebar. Remember that concrete has excellent compressive strength, but it is weak in tension. Reinforcing steel has excellent tensile strength but must be held in place with concrete to be effective.
Concrete and concrete are designed to bond and together are highly compatible and strong. CONC concrete spacers are made from high strength concrete, which bond perfectly with the surrounding concrete pour.
The composition of concrete and rebar is now widely used for the construction of concrete slabs/floors, concrete walls, concrete beams, concrete columns, elevated concrete floors, and concrete footings and foundations.
The concrete pour protects the rebar from aggressive environments, in addition to providing sufficient embedment to prevent slipping under stress. The depth of this concrete cover and positioning of the rebar within the concrete is critical to the structure being built and can also vary is dependent upon the environment to which the structure is exposed. Our concrete spacers come in a range of sizes and shapes to meet your requirements.
Concrete Spacers Strength
There’s no point substituting concrete spacers for inferior equivalents. The manufactured compressive strength of our concrete spacers is no less than 50MPa. 50MPa is equivalent to 7551.89 PSI. 7551.89 PSI is equivalent to 530.95 kilograms per square centimeter. That’s approximately one concert grand piano of weight for every square centimeter of concrete. Good luck trying to achieve this with plastic.
