Pengaruh penggunaan abu sekam padi terhadap sifat mekanis foam cement composite

Sari

Rice husk ash (ASP) is a waste from rice mills. This study aims to determine the effect of the use of rice husk ash on the mechanical properties of foam cement composite (FCC). Rice husk ash was added to the FCC mixture at a percentage of 0%, 3%, 6%, 9% and 12% by weight of cement. The methodology used to find the composition of the FCC is Trial & Error. The specimens used for compressive strength are 60x100x100 mm cubes of 60 pieces for the testing of 1, 3, 7 and 28 days of age, 10 cylindrical specimens of Ø150x300 mm for 10 days of splitting strength testing and 10x100x500 mm beam specimens of 10 for flexural strength testing at 28 days. The results showed that the use of rice husk ash to FCC did not affect the increase in compressive strength. Compressive strength on the use of 12% ASP was obtained at 34.09% from FCC control. In the testing of split strength and flexural strength, there was an increase, namely splitting strength increased by 42.04% and flexural strength increased by 7.17% from FCC control. So it can be concluded that the use of rice husk ash in the FCC mixture has a positive effect on splitting strength and flexural strength.
