Potential of excavation of c sand in Aek Bolon Village as a building material based on the material feasibility requirements test for concrete construction
Keywords:
Excavation C Sand, Concrete, Compressive StrengthAbstract
This study analyzed the feasibility of mountain sand in Aek Bolon Village, Balige District, as a fine aggregate in the concrete mixture. The methods used are exploratory and experimental research through laboratory tests at the University of Medan including sludge content, filter analysis, content weight, moisture content, specific gravity, absorption, and compressive strength of concrete aged 28 days. The test results showed a sludge content of 1.25%, Modulus of Fineness (FM) of 2.78 (medium sand), loose content weight of 1.26 gr/cm³ and density of 1.36 gr/cm³, moisture content of 3.63%, specific gravity of 2.40 gr/cm³, absorption of 2.3%, and an average compressive strength of concrete of 25.50 MPa (SNI 7656-2012). All parameters meet the fine aggregate feasibility standard. Thus, the mountain sand of Aek Bolon Village is suitable for use as a concrete mixture for building construction.
