The demand for lightweight concrete has been rising as this material is lighter in weight, making the load in the structure smaller. The lightweight used in this research was made from a mixture of water, cement, sand and foam. Besides the lighter smaller specific gravity, designing this lightweight foam concrete with compressive strength that is equivalent to the wall concrete commonly used of around 3-5 Mpa was also the target of this research. Unfortunately, foam concrete has weak tensile strength that it would withstand the vertical force of the wall when it is used for wall panel. This research was conducted to analyze the flexural strength and the shear strength of wall panel with GRC outer layer and wiremesh reinforcement. The test of flexural strength and shear strength employed wall panel of 50 mm think, 400 mm wide and 800 mm long. This test resulted in modulus elasticity value of 6856,6 MPa, compressive strength of 5,2 MPa and tensile strength of 0,7 MPa. The flexural strength of wall panel without GRC outer layer and without wiremesh reinforcement was found at 1,5 MPa. Meanwhile, the flexural strength of the wall panel with GRC outer layer without wiremesh reinforcement was found at 4,6 MPa. Finally, the wall panel applied with GRC outer layer and wiremesh reinforcement showed a flexural strength 5,3 MPa. |
