Cangkang telur merupakan limbah organik yang kaya akan kalsium karbonat
(CaCO₃), dengan kandungan mencapai lebih dari 90%. Selama ini, kebutuhan
CaCO₃ pada industri semen umumnya dipenuhi dari batu kapur, namun eksploitasi
batu kapur memiliki dampak lingkungan yang cukup besar. Oleh karena itu,
diperlukan alternatif yang ramah lingkungan dan berkelanjutan. Penelitian ini
bertujuan untuk mengevaluasi potensi bubuk cangkang telur sebagai accelerator
berbasis biomaterial.
Metode yang digunakan dalam penelitian ini adalah uji laboratorium eksperimental.
Bubuk cangkang telur dalam variasi konsentrasi 1%, 3%, dan 5% BWOC diuji
meliputi densitas, rheology, free water, API filtration loss, thickening time, dan
compressive strength. Hasil pengujian kemudian dibandingkan dengan slurry tanpa
aditif dan slurry dengan CaCO₃ konvensional.
Hasil penelitian menunjukkan bahwa penambahan bubuk cangkang telur mampu
mempercepat thickening time serta menurunkan nilai free water, filtration loss, dan
compressive strength. Efek penambahan paling optimal untuk parameter thickening
time ditemukan pada konsentrasi 3% BWOC. Penambahan 1% sudah menunjukkan
percepatan thickening time, sementara pada konsentrasi 5% terjadi sedikit
penurunan kinerja akibat kelebihan partikel padat. Dengan demikian, limbah
cangkang telur terbukti berpotensi sebagai akselerator alternatif yang ramah
lingkungan dalam aplikasi semen pemboran
Kata kunci: accelerator, cangkang telur, semen pemboran, thickening time

ABSTRACT
LABORATORY STUDY OF EGGSHELL AS AN
ACCELERATOR FOR OIL WELL CEMENT

Eggshell is an organic waste rich in calcium carbonate (CaCO₃), with a content
exceeding 90%. Traditionally, the demand for CaCO₃ in the cement industry has
been fulfilled using limestone; however, limestone exploitation has significant
environmental impacts. Therefore, an environmentally friendly and sustainable
alternative is needed. This study aims to evaluate the potential of eggshell powder
as a biomaterial-based accelerator.
The research method employed was an experimental laboratory test. Eggshell
powder was added at concentrations of 1%, 3%, and 5% BWOC and tested for
density, rheology, free water, API filtration loss, thickening time, and compressive
strength. The results were compared with slurry without additives and slurry with
conventional CaCO₃.
The results show that the addition of eggshell powder can accelerate thickening
time, reduce free water and filtration loss, and increase compressive strength. The
most optimal effect was found at a concentration of 3% BWOC. The 1%
concentration already showed significant improvements in physical performance,
while at 5%, a slight decline in performance occurred due to excess solid content.
Thus, eggshell waste has proven potential as an environmentally friendly
alternative accelerator in oil well cement applications.
