Abstract

Seiring perkembangan teknologi dalam bidang konstruksi. Beton digunakan pada kegiatan konstruksi seperti pekerjaan bangunan tinggi, jembatan, dan bendungan. Beton didefisinikan sebuah bahan komposit dengan penyusun utama agregat halus, agregat kasar, semen, dan air. Banyaknya limbah cangkang kerang hijau yang membuat kami tertarik untuk meneliti pengaruh penggantian serbuk cangkang kerang pada campuran beton terhadap kuat tekan dan kuat lentur beton. Tujuan dalam penelitian ini adalah menganalisa berapa kuat tekan dan kuat lentur optimum beton dengan variasi serbuk cangkang kerang 5%, 10%, dan 20% pada umur 14 dan 28 hari.Penelitian dilakukan dengan cara mix design, dengan membuat sampel beton Standar 25 MPa sebagai kontrol, kemudian membuat sampel beton variasi dengan campuran agregat halus serbuk cangkang dengan komposisi 5%, 10%, dan 20% dari kebutuhan agregat halus. Digunakan sampel silinder ( Ø = 15 cm, h = 30 cm) dan balok ( 15 x 15 x 60 cm). Sampel di uji kuat tekan dan kuat lenturnya pada umur 14 dan 28 hari.Dari hasil penelitian umur 14 hari nilai rata - rata kuat tekan beton standar yang didapat 25,46 Mpa, pada campuran 5% nilai kuat tekan 25,55Mpa, campuran 10% sebesar 29,504 Mpa, campuran 20% sebesar 27,1 Mpa. Dari hasil tersebut diketahui nilai kuat tekan paling besar adalah 10 %. Sedangkan pengujian kuat lentur benda uji berupa balok dengan ( 15 x 15 x 60 cm).Dari hasil pengujian umur 14 hari nilai rata - rata kuat lentur beton standar yang didapat 33,55 kg/cm², campuran 5% nilai kuat lentur 45,33 kg/cm², campuran 10% diperoleh 53,9kg/cm², campuran 20% nilai kuat lentur 60,759kg/cm².

Abstract

Along with advances technology in the field of construction. Concrete was used in construction activities such as high-rise buildings, bridges and dams. Concrete was defined as a composite material with the main constituent of fine aggregates, coarse aggregates, cement, and water. So much green seashells waste that made us interested to observe the effect of replacing shellfish shell powder on concrete mixtures on compressive strength and flexural strength of concrete. The aim of this study was to analyze the compressive strength and optimum flexural strength of the concrete with variations in clamshell powder 5%, 10%, and 20% at the age of 14 and 28 days. The research was carried out by means of mix design, by making Standard 25 MPa concrete samples as controls, then making a variation of concrete samples with a mixture of fine aggregates of shell powder with a composition of 5%, 10%, and 20% of fine aggregate requirements. Cylinder samples are used (Ø = 15 cm, h = 30 cm) and beams  (15  x  15  x  60  cm).  The  samples  were  compressive  strength  and  flexural strength at 14 and 28 days. From the results of the study at the age of 14 days the average value of the compressive strength of standard concrete was 25.46 MPa, in the mixture of 5% the compressive  strength  was  25.55  MPa,  the mixture of 10% was  29.504  MPa,  the mixture of 20% was 27.1 Mpa. From these result was known that the greatest compressive strength is 10%. While testing the flexural strength of the specimens in the form of blocks with (15 x 15 x 60 cm). From the results of the 14 day age test the average value of the standard concrete flexural strength obtained was 33.55 kg / cm², mixture 5% flexural strength value 45.33 kg / cm², 10% mixture obtained 53.9 kg / cm², mixture 20% flexural strength value 60.759kg / cm²
