Abstract: Peningkatan kuat tekan beton tanpa bahan tambah memiliki nilai yang berjalan lambat untuk memenuhi waktu pekerjaan yang ditargetkan maka untuk memenuhi kuat tekan yang besar dalam waktu singkat digunakan zat bahan tambah salah satunya ialah sikacim concrete additive yang berfungsi untuk mempercepat proses pengerasan beton. Tujuan dalam penelitian ini untuk mengetahui persentase optimal dalam penambahan sikacim concrete additive terhadap kuat tekan beton normal (variasi 0%). Beton yang direncanakan ialah K-175 dengan penambahan variasi persentase sebanyak 0 %, 0,4 % dan 0,85% dari berat semen. Pengujian kuat tekan beton dilakukan pada umur 7 hari, 14 hari dan 28 hari dengan menggunakan benda uji kubus 15 cm x 15 cm x 15 cm. Metode yang digunakan dalam penelitian ini menggunakan metode eksperimen. Pada penelitian ini didapat hasil berupa peningkatan kuat tekan beton sebesar 42,97 % pada variasi 0,4 % dan pada variasi 0,85 % terjadi peningkatan sebesar 66,99 % untuk beton berumur 7 hari dari beton normal. Pada umur beton 14 hari, variasi 0,4 % terjadi peningkatan sebesar 24,42 % dan pada variasi 0,85 % mengalami peningkatan sebesar 18,55 % dari beton normal. Pada umur beton 28 hari, variasi 0,4 % terjadi peningkatan sebesar 37,29 % dan pada variasi 0,85 % terjadi peningkatan sebesar 43,69 % dari beton normal. Kesimpulan dalam penelitian ini ialah bahwa penambahan variasi 0,85 % memiliki nilai kuat tekan beton tertinggi. The increase in compressive strength of concrete without added materials has a value that runs slowly to meet the targeted work time, so to meet the large compressive strength in a short time, one of the added materials is used, one of which is the sikacim concrete additive which serves to speed up the process of hardening concrete. The purpose of this study is to determine the optimal percentage in the addition of sikacim concrete additive to the compressive strength of normal concrete (variation 0%). The planned concrete is K-175 with additional percentage variations of 0%, 0.4% and 0.85% of the weight of cement. Concrete compressive strength testing was carried out at the age of 7 days, 14 days and 28 days using a cube test object of 15 cm x 15 cm x 15 cm. The method used in this study used experimental methods. In this study, results were obtained in the form of an increase in the compressive strength of concrete by 42.97% in a variation of 0.4% and in a variation of 0.85% there was an increase of 66.99% for concrete aged 7 days from normal concrete. At the concrete life of 14 days, a variation of 0.4% there was an increase of 24.42% and in a variation of 0.85% an increase of 18.55% from normal concrete. At a concrete age of 28 days, a variation of 0.4% there was an increase of 37.29% and in a variation of 0.85% there was an increase of 43.69% from normal concrete. The conclusion in this study is that the addition of a variation of 0.85% has the highest concrete compressive strength value.
