Abstract

According to SNI 03-2834-2000, concrete is a mixture of Portland cement, fine aggregate, coarse aggregate, and water with or without added materials to form a solid mass. Many studies have developed the building blocks of concrete mixtures to improve their quality and properties of concrete mixtures. In this study, lightweight brick waste from the rest of the construction project was used with a first refining process to pass a 0.3 mm sieve as a fine aggregate substitution mixture. The test object used is a cylinder with a size of 15 cm x 30 cm with variations in substitution of lightweight brick powder (SBR) 0%, 10%, 15%, 20%, and 30%. The method of calculating and testing materials and concrete specimens is guided by SNI 03-2834-2000. It was found that the substitution of SBR had a varying effect on the compressive strength of concrete. The maximum compressive strength was found at 21.44 MPa at 28 days, with an optimum SBR of 15% for fine aggregate.


ABSTRAK


Menurut SNI 03-2834-2000, beton adalah campuran semen, agregat halus, agregat kasar, dan air dengan /tanpa bahan tambah yang kemudian membentuk massa padat. Sebagai upaya meningkatkan kualitas dan sifat-sifat campuran beton, banyak penelitian yang mengembangkan bahan-bahan penyusun campuran beton. Dalam riset ini, limbah bata ringan yang berasal dari sisa proyek pembangunan diteliti dengan proses penghalusan terlebih dahulu hingga lolos ayakan 0,3 mm sebagai campuran substitusi agregat halus. Benda uji yang digunakan berbentuk silinder ukuran 15 cm x 30 cm dengan variasi substitusi serbuk bata ringan (SBR) 0%, 10%, 15%, 20%, dan 30%. Metode perhitungan dan pengujian material serta benda uji beton berpedoman pada SNI 03-2834-2000. Dari penelitian ini didapatkan hasil bahwa subtitusi SBR memiliki pengaruh yang bervariasi pada nilai kuat tekan beton. Nilai kuat tekan tertinggi sebesar 21,44 MPa pada umur 28 hari dengan persentase optimum subtitusi SBR sebesar 15% terhadap agregat halus.
