Properties of Pervious Concrete Containing Scrap Tyre Tubes

Abstract

Abstract. There is a huge quantity of waste tyre tubes generated every year due to the increasing of motorcycle user. Therefore, recycling of the waste tyre tubes is become mandatory. The aim of this research was to study the properties of pervious concrete containing scrap tyre tube (STT) rubber particles with percentages of 3%, 5% and 7% of the cement content. The properties studied are void content, compressive strength measured at 7, 14 and 28 days, flexural strength and flow rate which were determined at 28 day. The experimental results showed that, there were increased in void content and flow rate of pervious concrete containing STT. Both compressive strength and flexural strength of pervious concrete containing STT showed a lower value compared to the control mix without STT. The reductions of the mechanical strengths are likely due to the increase of void content. Overall, pervious concrete which contains 7% STT has shown an increment of mechanical strengths and flow rate compared to other STT pervious concrete. Nonetheless, the results indicate that there are potentials for use of STT in pervious concrete, especially for use in pervious concrete applications such as pavements, driveways and parking lots.

Environmental Implications of CO2 absorption by pervious concrete pavement in urban roads

“…In this research the methodology applied for the preparation of pervious concrete specimens was from ASTM C192, with the moulds made of PVC pipe, in the dimensions of 200.0 mm (height) by 100.0 mm (diameter), and the characterization of the aggregates was done by granulometry test, ASTM C136, of pebble and limestone aggregates, approximately 4.5 mm to 9.0 mm in size, through sieving. The methodology applied to the rubber tyre reuse STT specimens was the one performed by Boon et al (2017). The pebble aggregate, Figure 1, originated from the Juruá River (Amazon), the limestone, Figure 2, originated from the crushing processing of rocks found in the neighboring cities of Manaus (Amazonia) and the STT, Figure 3, used in this research originated from discarded used tyres in the city of Manaus (Amazonia).…”

“…The pebble aggregate, Figure 1, originated from the Juruá River (Amazon), the limestone, Figure 2, originated from the crushing processing of rocks found in the neighboring cities of Manaus (Amazonia) and the STT, Figure 3, used in this research originated from discarded used tyres in the city of Manaus (Amazonia). Recycling of used tires follows the methodology proposed by Boon et al (2017), carried out by processing the STT which is washed to remove impurities and cut into small rectangular shaped rubber particles, with an average size of 10.0 mm by 6.00 mm, for mixing during the manufacture of permeable concrete. The proportion of tube-rubber particles is 5% of the cement mass, about 19.0 kg/m³ of STT.…”

“…The proportion of tube-rubber particles is 5% of the cement mass, about 19.0 kg/m³ of STT. The value of 5% was proposed by Boon et al (2017) after conducting tests with the proportions of 3%, 5% and 7% to verify the physical properties with the mixture of STT in pervious concrete, which concluded that when STT is added to the mass of pervious concrete the physical properties of compressive strengths are impaired. In this research we have adopted the average value of 5% STT in relation to the pervious concrete mix so as not to overly affect the compressive strength property of our new pervious concrete material with STT.…”

“…The new pervious concrete group with Ca(OH)2 addition at a ratio of 1: 0.50: 4 (cement:Ca(OH)2:pebble) shows results about 15% to 20% loss than the pervious concrete control group, probably due to the internal pore structure of the pervious concrete that has been filled by the additives to make the material more compact and durable. The worst result was the new pervious concrete group with 5% STT added, because the addition of STT impairs the mechanical strength of the material (Boon et al, 2017), which shows that the addition of Ca(OH)2 and STT additives impair the compressive strength of the pervious concrete material. Excess additive in the pervious concrete mix impairs the pervious concrete mix making the material more fragile and poorly resistant.…”

Properties of Modified High Permeable Concrete with a Crumb Rubber

“…15 mix designs were used, and the results showed that it is possible to replace the aggregate with a crumb rubber but in correct proportion and with an appropriate granular size. Boon et al [9] also studied the properties of high permeable concrete but with the replacement of scrap tyre tubes. Their experimental studies have indicated that the use of scrap tyre tubes has increased the flow rate and void content.…”
