KARAKTERISTIK BETON RINGAN DENGAN MENGGUNAKAN TEMPURUNG KELAPA SEBAGAI BAHAN PENGGANTI AGREGAT KASAR (original) (raw)

The objective of the research is to know of lightweight conrete characteristic of endocarp which is consist of weight, compressive strength, elasticity modulus, tensile strength, flexure strength, and bond strength. The research had been done in the Concrete and Material Laboratory of Technic Faculty of Untad. The 18 components of lightweight aggregate experiments are 10 cylindrical (D15 x 30 cm), 5 squares (15 x 15 cm) and 3 rectangle (15 x 15 x 60 cm). The volume fraction endocarp lightweight aggregate that use is 0.35 and Cemen Water Factor (FAS) is 0.5 and the experiment of the component when it has been 28 days. In this research, it found the average of lightweight conrete characteristic of endocarp consist of the average of compressive strength is 14.054 MPa, Modulus elasticity wich is found from slant line of elastic curve (0.5 f'c) is 4595.590 MPa, tensile strength average is 1.713 MPa, flexure strength average is 2.329 MPa and bond strength average by used deform Ø 8.8 mm is 10.308 MPa.
