Effect of Waste Tyre Rubber Particles on Concrete Abrasion

 Rubberized concrete is a low-impact building material that replaces fine aggregate with rubber particles from old automobile tyres. Rubber particles can significantly improve the abrasion resistance of standard concrete besides offering several benefits. It has a promising future in hydraulic engineering, particularly in high-abrasion-resistance concrete building parts. However, there have been few experimental studies on the abrasion resistance of rubberized concrete and the impactful law and mechanism of rubber particles on the abrasion resistance of concrete are still unknown. All the scrap tyres buyers will agree to this unaltered truth.

 

What does research tell?

According to the findings, rubber particles increase the slump of concrete mixtures. The abrasion resistance of rubberized concrete increases significantly as the rubber particle content increases, whereas the compressive strength decreases linearly. For the same rubber particle size and content, abrasion resistance correlates with compressive strength, and larger rubber particles significantly improve abrasion resistance. Rubber particle content has the greatest influence on rubberized concrete abrasion resistance, followed by compressive strength. Pretreatment with NaOH + KH570 rubber particles, by the scrap tyres buyers, can significantly improve the abrasion resistance of rubberized concrete.

Effect of tyre rubber particles on water storage dams

Water storage in dams can provide long-term water resources for people's production and survival while also reducing flood damage at the very same time. This quite significantly proves effective for flood and disaster control. The height of dam construction is increasing as dam construction technology improves. More than 200 dams are over 100 metres high in the world, including the world's tallest arch dam, which is 305 metres high. The construction of a high dam necessitates more stringent requirements for concrete abrasion resistance. Even at low dam levels, the high sand and gravel content of flood discharge can cause serious damage to concrete structures. As a result, hydraulic researchers have always been interested in how to improve the abrasion resistance of concrete. Tyre rubber particles can be the solution to this problem.

How are the rubber particles from tyres used?

Rubber particles (RPs) from crushed automobile tyres are mixed into normal concrete (NC) in place of fine aggregate (sand), which not only recycles and alleviates the environmental harm associated with automobile tyre waste but also improves the engineering properties of NC, including several other advantages. Some of the merits are 

• shock resistance

• fatigue resistance

• corrosion resistance

• frost resistance

• abrasion resistance

and has thus, attracted extensive research attention from researchers across the world. The partial replacement of RPs in the aggregate changes the concrete failure mode from being brittle to ductile and plastic, increasing its ability to absorb a large amount of plastic energy under compression and tensile loads.

When the scrap tyres buyers grind the rubber tyres and form the rubber dust, they do so with the idea of promoting resistance to heavy flow of water especially in dams and they also go green. It goes completely unsaid how rubber forms an impressive resistance to moisture and when it is used with the expectation and plan of protecting people, settlements and habitations from severe and unexpected deluges, the results are indeed life-changing and life-saving.
