Abstract

Sebagai negara yang memiliki perairan yang luas beton tidak lepas dari pembangunan–pembangunan ditepi pantai maupun bangunan air. pemilihan campuran material–material penyusun beton sangat deperhatikan terutama dalam pemakaian beton didaerah pesisir yang umun terjadi kontak langsung dengan air laut. Karena air laut memiliki senyawa klorida (Cl) yang agresif terhadap bahan lain, termasuk beton. Serbuk kaca yang didapat dari limbah masyarakat menjadi inovasi peneliti yang diharapkan dapat memperbaiki kualitas beton akibat kontak langsung dengan air laut dimana sifat serbuk kaca penyerapan air yang minim. Beton memiliki kekurangan utama yaitu sifat getas sehingga menimbulkan retak pada beton, serat nylon efektif terhadap beton karena sifat dari polyamide/ nylon yang resisten dengan sejumlah material. Polyamide/ nylon juga dapat menambah resisten terhadap tumbukan dan juga efiktif untuk mempertahankan serta meningkatkan kapasitas beton. Penelitian dilakukan di Laboratorium FT-UKI perencanana mengikuti SNI 7656-2012 pada benda uji balok dimensi 15cm x 15cm x 60cm dengan kekuatan rencana f’c 25 Mpa pada umur 28 hari dan perawatan menggunakan air bersih dan air laut. Pada hasil pengujian terilihat peningkatan kuat tekan dan kuat lentur tertinggi untuk umur 28 hari dengan perawatan air bersih dengan variasi serat 1% yaitu 29,08 Mpa, sedangkan kuat lenturnya 3,813 Mpa. Pada air laut kuat tekan dan kuat lentur tertinggi untuk umur 28 hari dengan variasi serat 1% yaitu 28,45 Mpa, sedangkan kuat lenturnya 3,312 Mpa. Dapat dilihat bahwa kualitas beton dengan perawatan air laut lebih rendah dari perawatan dengan ait bersih. Kata kunci: Beton ramah lingkungan, perawatan air laut, serat Polyamide/ nylon, serbuk kaca, tekan dan lentur. / As a country that has vast waters, concrete cannot be separated from developments on the coast and water structures. the selection of a mixture of concrete constituent materials is very much considered, especially in the use of concrete in coastal areas where direct contact with sea water occurs. Because seawater has chloride compounds (Cl) which are aggressive to other materials, including concrete. Glass powder obtained from community waste is a research innovation that is expected to improve the quality of concrete due to direct contact with sea water where the properties of glass powder absorption of water are minimal. Concrete has the main drawback, namely brittleness which causes cracks in concrete, nylon fiber is effective against concrete because of the nature of polyamide/nylon which is resistant to a number of materials. Polyamide/nylon can also increase impact resistance and is also effective for maintaining and increasing concrete capacity. The research was conducted at the FT-UKI Laboratory according to SNI 7656- 2012 on test specimens with dimensions of 15cm x 15cm x 60cm with an f'c design strength of 25 MPa at 14 days and 28 days and treated using clean water and sea water. The test results show that the highest increase in compressive strength and flexural strength and 28 days with clean water treatment with 1% fiber variation, namely 29.08 Mpa, while the flexural strength 3.813 Mpa. In seawater, the highest compressive strength and flexural strength for ages 28 days with a variation of 1% fiber were 28.45 MPa, while the flexural strength was 3.312 MPa. It can be seen that the quality of concrete treated with seawater is lower than that treated with clean water. Keywords: Eco-friendly concrete, curing, seawater, polyamide/ nylon fiber, glass powder.
