Abstract

In the field of construction, particularly in geotechnical engineering, uncertainties in foundation design approaches are frequently encountered. Geotechnical uncertainties, especially in foundation design, pose complex challenges due to the heterogeneous nature of soil and data limitations. Dynamic load testing on pile foundations is an alternative method to static load testing in geotechnical engineering for evaluating pile capacity and behavior. The results of this analysis will be compared to the design capacity of pile foundations in the breasting dolphin structure. This study on a breasting dolphin structure utilizing Steel Pipe Pile (SPP) foundations with a diameter 610 mm. PDA tests were conducted on piles at points G6-23, G7-33, G7-38, and G8-46. The study begins with a literature review to comprehend methods and theories related to pile capacity analysis based on calendaring and PDA testing. Calendaring data were analyzed using empirical methods such as the Hiley Formula to estimate the dynamic bearing capacity of each pile. The pile capacity calculated using the Hiley Formula is generally higher than the results obtained from the Case Method and CAPWAP Analysis. The relationship between pile capacity based on the Hiley Formula (calendaring) and the Case Method (PDA test) yielded a linear regression equation of y = 1.0785x - 983.07 with R² = 0.2385, indicating a weak correlation. Meanwhile, the relationship between pile capacity from the Hiley Formula (calendaring) and CAPWAP Analysis (PDA test) resulted in a linear regression equation of y = -0.006x + 2909.8 with R² = 1×10?¹, indicating almost no linear correlation between the two.

Abstract

This study aims to characterize the effect of superplasticizer addition on local aggregate concrete workability and early-age compressive strength. The methodology involved the use of Portland Composite Cement, local fine and coarse aggregates, and Fosroc Auracast SP310 superplasticizer at dosages of 1%, 1.6%, and 2%. Four concrete mix designs were prepared: normal concrete (BN) and concrete with superplasticizer additions (BN-1%, BN-1.6%, BN-2%). Slump and compressive strength tests were conducted according to Indonesian standards to assess workability and strength at 7 and 14 days. Results indicate that superplasticizer addition significantly improves concrete workability with slump values ranging from 560 to 630 mm compared to 115 mm for the control. Compressive strength also increased markedly, with BN-2% showing the highest strength at 38.56 MPa at 7 days and 51.94 MPa at 14 days. The study concludes that superplasticizer effectively enhances both workability and compressive strength without increasing water demand, resulting in denser and stronger concrete at early curing ages.
