Abstract In this research work, waste rubber obtained from tires is mainly used as a fractional substitution of natural coarse aggregate to improve the strength aspects of the concrete. 3 dissimilar sizes of waste rubber obtained from tires aggregates were used that is of 4mm, 10 mm and 16 mm. Depending upon all three sizes all the waste rubber obtained from tires aggregate were used at 3 different percentages that are at 10 percent, 20 percent and 30 percent. Then several concrete samples were prepared depending upon the shape and percentage of the waste rubber obtained from tires aggregate. Then all these samples were cured and tested after 7 days and 28 days. Depending upon the results obtained after these above-discussed test various conclusions has been drawn which are as follows. It was found that the maximum strength was obtained at 20 percent usage of 4mm sized waste rubber obtained from tires aggregate, the strength obtained at 20 percentage with 4mm size was maximum as compared to all other concrete samples, so it can be concluded that the compressive strength depends upon both the size as well as on the percentage of waste rubber obtained from tires aggregate and with the decrease in size of the waste rubber obtained from tires aggregate the strength was increasing. From the test results of the split tensile strength test and flexural strength test, it was found that the maximum strength was obtained at 20 percent usage of 4mm sized waste rubber obtained from tires aggregate and with the increase in size and percentage the strength was declining. So therefore it can be concluded that both split tensile strength and flexural strength depends upon the size of waste rubber obtained from tires aggregate and the percentage of waste rubber obtained from tires aggregate. From the obtained test results it can be concluded that with the addition of the waste tire rubber the overall internal micro-structure of the concrete improves which further leads to enhanced mechanical strength of the concrete. This was due to the physical properties and the chemical composition of the waste tire rubber particles which fills the internal pores in a broader way and lead to improved mechanical strength.

Constituent Elements

We all know that steel elements cannot be renewed and their constituent elements take a long time to form. So there is a need for other alternatives which have steellike properties. One alternative is bamboo, bamboo is one material that can be used as a substitute for steel, because bamboo has a high tensile strength close to the strength of steel. In this study an attempt was made to compare the use of reinforcement with bamboo on the outside with the skin and the inside without skin to determine the flexural strength. The flexural strength test results on variations of skin obtained the value of Max P: average: 3400 kg with an average deflection of 9.25 mm while in variations without the skin P Max produced an average of 2400 kg with deflection value of 1.92 mm. Kita ketahui bersama bahawa unsur baja tidak bisa diperbaharui serta unsur penyusunnya yang membutuhkan waktu yang lama untuk terbentuk. Sehingga  perlu adanya alternatif  lain yang dimana memiliki sifat menyerupai baja. Salah satu alternatifnya adalah bambu, bambu merupakan salah satu bahan dapat digunakan sebagai pengganti baja, karena  bambu mempunyai kuat tarik yang tinggi yang mendekati kekuatan baja. Pada penelitian ini dicoba untuk membandingkan penggunaan tulangan dengan bambu bagian luar dengan kulit dan bagian dalam tanpa kulit guna mengetahui kekuatan lentur. Hasil pengujian kuat  lentur pada variasi kulit didapatkan nilai P Maks: rata-rata:3400 kg dengan  lendutan  rata-rata 9.25 mm sedangkan pada variasi tanpa kulit P Maks rata-rata yang dihasilkan 2400 kg dengan nilai lendutan 1.92 mm.

This paper studies the effect of incorporating metakaolin on the mechanical properties of high grade concrete. Three different metakaolins calcined at different temperature and durations were used to make concrete specimens. Three different concrete mixtures were characterized using 20% metakaolin in place of cement. A normal concrete mix was also made for comparison purpose. The compressive strength test, split tensile test and flexural strength tests were conducted on the specimens. The compressive strength test results showed that all the metakaolin incorporated concrete specimens exhibited higher compressive strength and performed better than normal concrete at all the days of curing. The rate of strength development of all the mixes was also studied. The study revealed that all the three different metakaolin incorporated mixtures had different rate of strength development for all the days of hydration (3, 7,14, 28, 56 and 90), indicating that all the metakaolins possessed different rate of pozzolanic reactivity. Further, from the analysis of the test results, it was concluded that the variation in the rate of strength development is due to the differences in the temperature and duration at which they were manufactured. The results of split tensile strength test and the flexural strength test conducted on the specimens, supported the conclusions drawn from the results of compressive strength test. The paper also discusses, the rate of development of compressive strength and the pozzolanic behaviour of the metakaolins in light of their parameters of calcination and physical properties such as amorphousness and particle size. This paper has been written with a view to make the potential of metakaolin available to the construction industry at large

Preparation Techniques

Geotextiles are made of polymers, and their conjunction with different processes and materials can provide geotextiles with desirable characteristics and functions, such as filtration, separation, and drainage, and thereby meets the environmental requirements. Chemical resistant and mechanical strong polymers, including polyester (PET) and polypropylene (PP), are thus used to prolong the service life of the products made by such materials. This study proposes highly air permeable geotextiles that are made with different thicknesses and various needle punching speeds, and the influences of these two variables over the pore structure and mechanical properties are then examined. PET fibers, PP fibers, and recycled Kevlar fibers are blended, followed by being needle punched with differing spaces and speeds to form geotextiles with various thicknesses and porosities. The textiles are then evaluated for their mechanical strength and porosity. The test results show that a thickness of 4.5 cm and 1.5 cm demonstrate an influence on the tensile strength of the geotextiles, which is ascribed to the webs that are incompletely needle punched. However, the excessive needle punching speed corresponding to a thickness of 0.2 cm results in a decrease in tensile strength, but there is also an increase in the porosity of the geotextiles.
