| Abstract: | Precast concrete is chosen for its time efficiency and ease of installation, however mix workability is often a challenge without compromising compressive strength. Superplasticizer (SP) is used to improve the fluidity of concrete without
adding water. This study examined the effect of varying SP dosage (0%; 0.6%; 0.7%; 0.8%) on slump values and compressive strength of concrete at 7, 14, and 28 days. The results showed that the addition of SP increased the workability and compressive strength of concrete. The 0.8% dosage produced the highest workability and compressive strength at 28 days of 5.4 cm and 54.68 MPa, respectively, compared to 43.45 MPa at 0% dosage. Pearson correlation showed a
strong positive relationship between SP dosage and slump and compressive strength values, although not statistically significant (p > 0.05). That is, the higher the SP dosage, the higher the compressive strength and slump values tended to be. However, the significance level (p-value) for all variables was above 0.05, meaning that the relationship was not statistically significant. Beton pracetak dipilih karena efisiensi waktu dan kemudahan instalasi, namun workabilitas campuran sering menjadi tantangan tanpa mengorbankan kuat tekan. Superplasticizer (SP) digunakan untuk meningkatkan fluiditas beton tanpa menambah air. Penelitian ini mengkaji pengaruh variasi dosis SP (0%; 0,6%; 0,7%; 0,8%) terhadap nilai slump dan kuat tekan beton pada umur 7, 14, dan 28 hari. Hasil menunjukkan bahwa penambahan SP meningkatkan workabilitas dan kuat tekan beton. Dosis 0,8% menghasilkan workabilitas dan kuat tekan tertinggi pada umur 28 hari masing-masing sebesar 5,4 cm dan 54,68 MPa, dibandingkan 43,45 MPa pada dosis 0%. Korelasi Pearson menunjukkan hubungan positif yang kuat antara dosis SP dengan nilai slump dan kuat tekan, meskipun secara statistik tidak signifikan (p > 0,05). Artinya, semakin tinggi dosis SP, cenderung semakin tinggi pula kuat tekan dan nilai slump. Meskipun demikian, tingkat signifikansi (p-value) untuk seluruh variabel berada di atas 0,05, yang berarti hubungan tersebut tidak signifikan secara statistik. |
