Study of Improving Soil Using Permit, Corn Ash and Sodium Silicate

Abstract

Soil that has low bearing capacity has a bad impact on the construction that is built on it as a result of which the building is easily damaged such as lifting the foundation on the building and causing cracks and shifting on the road. This research uses experimental laboratory methods. Soil samples used were taken from Lembang Tondon Siba’ta, Tondon District. Corn cobs were taken from Sa’dan Marante, Sodium silicate is obtained from chemical figures and palm fiber taken from Buntu Tagari and then tested for soil physical characteristics and soil bearing capacity in soil samples with a mixture of sodium silicate, corncob ash, palm fiber and soil without mixture. know the bearing capacity of the soil. The results of the research on stabilized soil by adding 0.2% palm fiber, 2% corncob ash and 3% sodium silicate obtained an increase in soil bearing capacity of 9.73% from the original soil and the addition of 0.2% palm fiber, 4% corncob ash and 3% sodium silicate.
