Recycled Rubber Tyres as Aggregate in Concrete Essay

Recycled Rubber Tyres as Aggregate in Concrete - Essay Example The paper tells that the ability to change the levels of consumption in the UK is one which is essential to the needs to create a sustainable world and to alter the pollutants which are coming from different resources. A technology which is being created is with the use of recycled rubber tyres. There is the option of allowing this to work as an aggregate in concrete, specifically to begin changing the consumption in the UK and to begin lowering the number of toxins with the tyre production that occurs every year. While there is a large amount of consumption and changes with the tyres, there is also a question of whether the aggregate in the concrete is able to create the same substance and material responses as other forms of technology for concrete. This is able to alter and change the way in which the aggregate can be used while determining if the tyres can be recycled into a different substance for other needs. The first question which is associated with the recycled rubber parti cles is based on the understanding of cement paste and how it responds and reacts to the rubber tyre particles being added as a part of it. In a study of Segre Joekes, there was a modification to the cement by adding in rubber tyre powder to the aggregate. The study looked at the cement paste and the way that the surface began to change after a period of 20 minutes. The substance was examined in terms of absorption, density, flexural strength, compressive strength, abrasion resistance, elasticity and fracture energy measurements. The measurement then looked at the level of Sodium Hydroxide (NaOH) with the rubber. It was found that the rubber not only assisted with the mix of the materials in the cement but also increased the level of flexibility, durability, toughness and compressive strength. The conclusion was not only with the improvement of quality with the cement. It was noted that by using the rubber tyres as a part of the cement, different formats for roads and other road con struction areas could be used. The substance which was created from the recycled rubber tyres is one which is not as course, meaning that the use on road construction can help with more durability and sustainability with the recycled rubber (Segre, Joekes, 2000: 1421). The overall changes which were made with the concrete also refer to the rubber tyres changing the properties of the cement to create different levels of substance to be used in different areas. The association with tyres is one which is able to automatically change and assist with the overall needs and properties for strength, specifically with roads and areas which have continuous use and fluctuation. The changes with the cement also show that the use of magnesium oxychloride, a natural property found in rubber, is able to provide more functioning for the cement. This particular substance is able to work to bind the concrete mixtures in a way that improves the strength and durability of the substance. The rubberized concrete not only has the ability to directly impact and improves the concrete which is used. The magnesium oxychloride as a binding substance can help in changing the way in which concrete is used and allows the mixture to provide even more solutions to the substance. The substance differs with the types of tyres which are used, amount that is mixed with the concrete and is dependent on factors such as unit weight, air content and slump. Incorporating these into the mixture is then noted as essential for creating the correct mixture and alternatives with the rubber tyres and concrete mix that is used (Siddique, Naik, 2004: 563). 2.2 Compressive Strength The additional alternatives which are a part of the rubber tyres used in aggregate
