Abstract: | Beton sebagai bahan konstruksi terus meningkat penggunaannya karena
kuat tekannya yang tinggi dan mudah dalam pengerjaannya. Pengelolaan sampah
plastik menjadi persoalan karena plastik sulit untuk diuraikan secara alami.
Subtitusi plastik saja tidak dapat dilakukan pada beton, sehingga diperlukan
tambahan lain untuk mempertahankan kekuatan beton. Soybean crude urease
calcite precipitation (SCU-CP) dijadikan sebagai alternatif pemecahan masalah
dengan menggunakan kedelai sebagai pengganti enzim urease yang dapat
meningkatkan kekuatan tanah. Oleh karena itu diperlukan evaluasi pengaruh
subtitusi plastik serta penambahan larutan kalsit terhadap kuat tekan dan
tegangan-regangan beton. Peningkatan kuat tekan terjadi secara signifikan pada
beton plastik SCU-CP 5%. Penambahan kalsit meningkatkan tegangan dan
menurunkan regangan yang menjadikan kurva semakin tegak, modulus elastisitas
meningkat dan mutu beton semakin bagus. Concrete as a construction material continues to increase in use because of its high compressive strength and ease of operation. Plastic waste management is a problem because plastic is difficult to decompose naturally. Plastic substitution alone cannot be done on concrete, so other additions are needed to maintain the strength of the concrete. Soybean crude urease calcite precipitation (SCU-CP) is used as an alternative problem solving by using soybeans as a substitute for urease enzymes which can increase soil strength. Therefore, it is necessary to evaluate the effect of plastic substitution and the addition of calcite solution on the compressive strength and stress-strain of concrete. The increase in compressive strength occurred significantly in the 5% SCU-CP plastic concrete. The addition of calcite increases the stress and decreases the strain, which makes the curve more upright, the modulus of elasticity increases, and the concrete quality gets better. |
