Abstract
Self Compacting Concrete (SCC) adalah beton segar yang mampu mengalir mengisi bekisting dengan sendirinya tanpa memerlukan alat penggetar. Salah satu penyebab kerusakan bangunan saat terjadi gempa bumi yaitu berat sendiri struktur. Agregat ringan merupakan salah satu cara untuk mereduksi berat stuktur, oleh karena itu self compacting concrete beragregat ALWA merupakan suatu solusi untuk mereduksi beban mati struktur dengan kemudahan pelaksanaan pengerjaan.
Penelitian ini dilakukan untuk mengetahui seberapa besar kuat tekan, modulus elastisitas, kuat tarik belah dan kuat tarik lentur pada masing-masing variasi komposisi ALWA sebagai pengganti agregat kasar pada Beton Normal dan SCC. Proporsi ALWA yang disubstitusi ke dalam beton yaitu 0%, 15%, 50% dan 100%. Benda uji yang digunakan berbentuk silinder dengan ukuran tinggi 200 mm dan diameter 100 mm untuk pengujian kuat tekan, modulus elastisitas dan kuat tarik belah. Sedangkan benda uji berbentuk balok dengan ukuran 150 mm x 150 mm x 600 mm untuk pengujian kuat lentur.
Hasil dari pengujian kuat tekan menunjukkan bahwa semakin tinggi variasi komposisi ALWA maka semakin rendah kuat tekan yang dihasilkan. Penambahan ALWA sebagai pengganti agregat kasar pada campuran beton normal dan SCC paling efektif terjadi pada kadar 15% ALWA dengan kuat tekan pada beton normal dan SCC yang dihasilkan sebesar 21.13 MPa dan 28.33 MPa. Sedangkan untuk nilai modulus elastisitas pada beton normal yaitu 20843.99 MPa dan modulus elastisitas SCC sebesar 23717.77 MPa. Kuat tarik belah beton normal adalah 2.23 MPa dan SCC adalah 2.32 MPa. Nilai modulus runtuh dari beton memadat sendiri (SCC) dengan kadar 15% ALWA yaitu sebesar 5.029 MPa.

Self Compacting Concrete (SCC) is a fresh concrete that can flow filling the formwork by itself without need the vibrator. One of the causes of damage to buildings during an earthquake is its own weight structure. Lightweight aggregate is one manner to reduce weight of the structure, therefore self compacting concrete with ALWA aggregate is a solution to reduce dead load structure with ease of processing.
This research was conducted to find out how big compressive strength, modulus of elasticity, tensile strength and flexural strength in each variation of ALWA composition as a substitute of coarse aggregate on regular concrete and SCC. The proportion of ALWA substituted into the concrete is 0%, 15%, 50% and 100%. The test specimens used are cylindrical in size 200 mm and diameter 100 mm for testing of compressive strength, modulus of elasticity and tensile strength. While the specimens beam with the size of 150 mm x 150 mm x 600 mm for testing of flexural strength.
The results of the compressive strength test show that the higher composition of ALWA the lower compressive strength. The addition of ALWA as a substitute of coarse aggregate to regular concrete and SCC most effective occurred at 15% ALWA with compressive strength on regular concrete and SCC is 21.13 MPa and 28.33 MPa. While the modulus of elasticity value in regular concrete is 20843.99 MPa and modulus of elasticity in SCC is 23717.77 MPa. The tensile strength of regular concrete is 2.23 MPa and SCC is 2.32 MPa. The modulus rupture of Self Compacting Concrete (SCC) with 15% ALWA is 5.029 MPa.
