ABSTRAK

Sonny Bhaksono Aji, 2018. Pengaruh Persentase Fly Ash terhadap Properti

High Volume Fly Ash Self Compacting Concrete. Skripsi Program Studi Teknik

Sipil Fakuktas Teknik Universitas Sebelas Maret, Surakarta.

Penggunaan supplementary cementing material yang bersifat pozzolan seperti fly ash

banyak dipertimbangkan karena selain efektif me-reduce penggunaan portland

cement, fly ash juga merupakan limbah pembakaran batu bara yang kurang

termanfaatkan. High volume fly ash self compacting concrete dapat menghasilkan

sustainable concrete dengan mechanical strength yang tinggi dan workability yang

baik. Beberapa penelitian tentang HVFAC sendiri sudah pernah dilakukan namun

belum ada yang membahas tentang properti HVFAC padahal untuk diaplikasikan

dalam desain perencanaan dan perancangan struktur dibutuhkan properti-properti

beton. Oleh sebab itu penelitian ini bertujuan untuk menganalisis properti-properti

pada HVFASCC.

Penelitian ini bersifat eksperimen kuantitatif dan dilakukan di Laboratorium Struktur

dan Bahan Program Studi Teknik Sipil Universitas Sebelas Maret. Penelitian

menggunakan 1 mix design beton normal usia 28 hari dan 3 variasi mix design

HVFASCC usia 90 hari dengan fly ash replacement ratio 50%, 60% dan 70%

dengan total cementitious 500 kg/m3. Spesimen yang digunakan adalah silinder 150

x 300 mm sejumlah 3 buah untuk tiap mix design. Pengujian yang dilakukan meliputi

pengujian beton segar dan hardened concrete. Untuk destructive test dilakukan

sesuai standar ASTM C469 dengan compressive testing machine. Dari penelitian ini

didapatkan nilai kuat tekan, regangan, hubungan tegangan dan regangan, modulus

elastisitas dan rasio poison..

Hasil pengujian beton segar menunjukkan workability semakin baik seiring

peningkatan fly ash replacement ratio. Pengujian hardened concrete untuk NC.90,

HVFA.90.50, HVFA.90.60, HVFA.90.70 menghasilkan kuat tekan 74,98 MPa, 74,60

MPa, 58,95 MPa, 46,50 MPa, regangan puncak 0,00164, 0,00183, 0,00190, 0,00211,

modulus elastisitas 46,8 GPa, 44,8 GPa, 35,2 GPa, 24,5 GPa dan rasio poison 0,162,

0,191, 0,189, 0,183. Pola grafik ascending curve pada hubungan tegangan regangan

hasil eksperimen dibandingkan dengan persamaan Domingo, CEB dan Hognestad.

Adanya perbedaan nilai dari besaran-besaran diatas terjadi karena adanya evolusi

dari reaksi yang terjadi pada flyash-cement blends yang melibatkan degree of

hydration dan degree of reaction.

ABSTRACT

Sonny Bhaksono Aji, 2018. Effect of Fly Ash Content to Properties of High

Volume Fly Ash Self Compacting. Undergraduate Thesis of Undergraduate Degree

Civil Engineering, Sebelas Maret University, Surakarta.

The use of pozzolanic supplementary cementing materials such as fly ash in concrete

mixture is highly considerable, it reduces the usage of portland cement and also

reuse the underutilized waste from coal burning. High volume fly ash self-

compacting concrete is able to provide sustainable concrete with high mechanical

strength and great workability. Many researches related high volume fly ash

concrete has been done, but none of them discuss about the concrete properties of

HVFAC, even though in field of structure design the properties of concrete is highly

required. Therefore, this study aims to analyze the behavior of stress strain on

HVFASCC.

This is a quantitative experiment research and conducted in the Structural and

Materials Laboratory Civil Engineering Department, Sebelas Maret University. The

study use 1 mix design for 28 days normal concrete and 3 different mix design of for

90 days HVFASCC with fly ash replacement ratio 50%, 60% and 70% from 500 kg /

m3 cementitious content. The specimen used is a cylinder 150 x 300 mm of 3 pieces

for each mix design. Tests include fresh concrete and hardened concrete testing.

Destructive tests execute according to ASTM C469 by using compressive testing

machine. From this research, the value of compressive strength, strain, stress and

strain relationship, modulus of elasticity and poison ratio is determined

Fresh concrete test shows that the workability of concrete increasing with the

increasing of fly ash replacement ratio. Destructive test generates to evaluate the

hardened concrete and the result for NC.90, HVFA.90.50, HVFA.90.60, HVFA.90.70

is 74.98 MPa, 74.60 MPa, 58.95 MPa, 46.50 MPa for compressive strength,

0.00164, 0.00183, 0.00190, 0.00211 for peak strain, 46.8 GPa, 44.8 GPa, 35.2 GPa,

24.5 GPa for modulus of elasticity and 0.162, 0.191, 0.189, 0.183 for poisson ratio.

Experimental stress-strain ascending curve compared with establish equation which

is Domingo, CEB and Hognestad’s model. The difference value in some concrete

properties as shown above caused by the evolution of the reaction occurring in the

fly ash-cement blends that involving degree of hydration and the degree of reaction.

Keywords: HVFASCC, concrete properties, fly ash.
