Aprianti, Kartini (2017) Pengaruh Metode Two-Stage Mixing Approach (TSMA) terhadap Kuat Tekan Beton Porous dengan Variasi Komposisi Agregat Kasar Daur Ulang (RCA). Sarjana thesis, Universitas Brawijaya.
Abstract
Betonnporousnadalah salah satu jenis beton yangnmempunyai rongga udaranlebih besar sehingga memungkinkan airnuntuknmengalir melalui rongganbeton dan dapat diserap oleh tanah. Adanya rongganudara yang lebih besar, mengakibatkan kuat tekan beton porous lebih rendah dibandingkan beton konvensional.mPenggunaan beton porous dapat dikembangkan lagi dengan mengganti sebagian atau seluruh agregat kasar alam (NCA) dengan agregat kasar beton daur ulang (RCA). Kualitas RCAnumumnyanlebih rendah daripadanNCA, sehingga metodenTwo-Stage Mixing Approach (TSMA) diharapkanndapatnmeningkatkannkualitas beton porous yang.menggunakan.RCA. Pengujian material pada penelitian ini meliputi berat isi, berat jenis, dan penyerapan air pada agregat kasar. Sedangkan pengujian untuk beton porous meliputi berat isi dan kuat tekan. Uji tekan dilaksanakan untuk mengetahui pengaruh komposisi RCA dan metode pencampuran terhadap kuat tekan beton porous.nPersentase RCA yang.digunakan yaitu 0%, 25% 50%, 75%, dan 100%, sedangkan metodenpencampurannyangndigunakan yaitu Normal Mixing Aggregates (NMA) dan Two-Stage Mixing Approach (TSMA). nnn Pengujian tekan dilakukan pada umur beton 28nharindengan alat Compressing Testing Machine (CTM).mBerdasarkan hasil pengujian didapatkan kuat tekan rata-rata maksimum yaitu pada komposisi RCA 100% dan metode TSMA dengan nilai 11,81 MPa. Pada penelitian ini, hasil pengujian kuatntekannmemenuhi syarat ACI 522R-10 tentang beton porous.
English Abstract
Porous concrete is a type of concrete that has a larger pore to allows water to flow through the concrete pores and absorbed by the soil. Because it have larger pores, the compression strength of porous concrete is lower than conventional concrete. The use of porous concrete can be further expanded by replacing some or all of the natural coarse aggregates (NCA) with recycled coarse aggregate (RCA). The quality of RCA is generally lower than NCA, so the Two-Stage Mixing Approach (TSMA) was expected to improve the quality of porous concrete using RCA. The test for material in this research included the density, specific gravity and water absorption of coarse aggregates. While the test for porous concrete included the density and compression strength. These test were conducted to determine the effect of RCA composition and mixing methods on the compression strength of porous concrete. The percentage of RCA used were 0%, 25% 50%, 75%, and 100%, while mixing methods were Normal Mixing Aggregates (NMA) and Two-Stage Mixing Approach (TSMA). The compression strength test was performed at 28 days of concrete using Compressing Testing Machine (CTM). Based on the test results, the maximum compression strength was retained by 100% RCA composition and TSMA method with a value of 11.81 MPa. In this research, the results of compression strength fulfill ACI 522R-10 requirement about porous concrete.
