Abstract

This research aims to study the utilization of residual stone powder from stone crushers as a substitute for sand in mortar mixtures and to analyze the effect of stone dust variations on the compressive strength characteristics of mortar. The stone powder variations used are 0%, 22%, 26%, 30%, 34%, and 38%, with a total of 72 samples. Compressive strength testing was conducted at 14 and 28 days of age with immersion using PDAM water and swamp water. The results showed that the optimal substitution of stone powder is between 22% - 36%. The highest compressive strength was obtained at a 22% variation with a value of 14.21 MPa (PDAM water) and 13.71 MPa (swamp water). Conversely, the lowest compressive strength was recorded at a 38% variation with a value of 6.15 MPa (PDAM water) and 5.75 MPa (swamp water). Immersion using PDAM water (pH 6.34) produced higher compressive strength values compared to swamp water (pH 4.36), indicating that water pH affects the final results of the mortar. This study recommends the use of stone powder as a sand substitute in mortar production to achieve good quality.

Abstract

The Air Meranjat Bridge - Batas Kota Kayu Agung, Ogan Ilir Regency, South Sumatera connects the Indralaya - Kayu Agung cross Sumatra road. The design of the Air Meranjat bridge includes the upper structure and lower structure using the Practical Guide to Bridge Technical Planning method 2021. From the design results obtained the dimensions of the prestressed girder 1.7 m x 0.7 m and a length of 40.6 m, Pillars with dimensions of 3.929 m x 4 m and a length of 11 m, Abutment with dimensions of 6.35 m x 5 m and a length of 10.6 m, Piles used diameter 0.5 m 24 m depth. The cost for the construction of the Air Meranjat Bridge is Rp.10.555.155.490,000 with an implementation time of 202 days.
