Introduction

Ecological development is become the prime focus and responsibility of the civil engineers, engineers and society are collectively working for development and validating environment approachable solutions for recycling materials and scrap management is the one type construction part of civil infrastructure. For the past decades, there has been a drastic change in the way of thinking about the approach and evolution of new and advance construction materials. Aborting of waste tyre rubber and waste plastic are one of the major concerns for all over the world. With drastic increase in the country automobiles and waste plastic during the past few decades, the demands of utilization of both are increased. The disposed materials are to the landfills constitutes one of the important part of solid waste from the remaining. Among the disposal methods, burning of tyres & plastic in open air is causing serious fire hazards. Besides this, the final residue after burring pollutes the fresh atmosphere by increasing carbon monoxide reducing the oxygen levels as well as the natural earth by its deposition. By the end of 2040, the number of tyres deposition in to landfills from automobiles is about to reach 1600 million assuming that almost 7000 million tyres will be discharged. India ranked second largest producer in the world. According to FICCI study The processing of plastic materials and related industry is estimated to grow to twenty two metric tonnes (MT) a year by 2020 from in 2015 the estimated grow is 13.4 only , this paper major aim is utilizing the bias tyres rubber and plastic use as replacement materials for the concrete mix [1].

Research Significance

• Durable & Corrosion Resistant

• Good insulation in summer and winter seasons

• It is cost effective

• Maintenance free

• Longer life span

Used materials

• Crumb Rubber

• Waste plastic

• Cement

• Fine aggregate

• Coarse aggregate

• Water

• Admixture

Methodology & Tests

I casted the required cube specimens of sizes 150 mm × 150 mm × 150 mm according to Indian standards followed by Mix Design, Mix design was formulated according to IS 10262-2009 and used IS 456-2000 [2,3].

Also Conducted the material Tests on Portland cement of grade 53 Deccan cement, zone –II sand with fineness modulus 2.2 and coarse aggregates used are 12 mm and 20 mm angular sizes used, I got the satisfactory results on raw materials (Table 1, Figures 1, 2 and 3).

Table 1. Results on raw materials.

Conclusions

• This research is entirely new, by studying all the literature reviews of the waste plastic, crumbled rubber I set a perspective stage on by combining the both environment hazard materials in environment concern as wells it is useful to construction industry I think so.

• Both materials are very tough in nature and very useful when they are in civil engineering constructions too.

• By observing all the compressive strength results about this combination is a good one generally we have 65 % compressive strength for first seven 7 days in normal concrete mix, after casting cubes of the virgin mix we got 72 % of compressive strength achieved while testing.

• After testing 28 days compressive strength cubes we get what we expected, normal we have a target mean strength of 48.25 N/mm2, we obtained 53.38 N/mm2 at 28 days as for the replacement of 15% of crumb rubber and 5 % waste plastic [5].

• From the compressive strength results we obtained positive results in every stage of mixing those two materials.

• On other hand we have split tensile strength for the cylinders for the curing periods of seven and Twenty-eight days.

• Observing the graph, we have best replacement is 10 % of crumb rubber and waste plastic.

• We conducted UPV test on cubes in every aspect got excellent and good in quality of concrete.

• We need to further checks on long term curing periods too like 56 days and 90 days.

• Concrete can be assessed on long term curing periods, we suggest this also a new replacement among the advanced materials.
