“…In recent years, the use of nanomaterials has been shown to increase the effectiveness of stabilizers. The difference in particle size of the soil and overlapping nanomaterials can reduce the percentage of voids in the soil, sufficient to obtain significant improvements in the physical and chemical properties of the soil [5]. The use of nano-silica 0.910 kg/m^3 and quicklime 25.35 kg/m^3 was able to increase the CBR index value by 50%.…”

This decade, a lot of soil stabilization research, especially expansive soils, uses nano materials. This is because many regions in Indonesia have expansive clay soil types, one of which is in Cilin Village, Bandung City, West Java Province. Expansive soils have low soil carrying capacity in high water table conditions. This condition surrounded the building above it. Disadvantages due to low carrying capacity of expansive soil, stabilization is needed to increase soil carrying capacity. It's just that the procurement of micro materials is very expensive. For this reason, this paper will explain the effectiveness of nano materials when compared to micromaterials. The main focus that will be discussed in this paper is how to compare the value of laboratory unsoaked CBR between micromaterials and quicklime nanomaterials in expansive soils. The research was conducted at the Bandung State Polytechnic Laboratory. This study used a stabilization method by adding 2% lime to each particle size. The procurement price of nanomaterials is Rp. 2,500,000 and micromaterials Rp. 1,500,000. The CBR test result obtained is native soil is 8.49; mixed soil 2% lime micromaterial is 9.01; and the soil mixture of 2% lime nanomaterial is 9.22. The difference in CBR value is only 0.21, so the more effective result is the unsoked condition of adding 2% lime micromaterial at a cheaper price.

Expansive soils are soils that have high shrinkage expansion. This condition is detrimental to buildings on it. Losses due to swelling and shrinkage in expansive soils require stabilization with quicklime with varying particle sizes of materials needed to reduce soil swelling and shrinkage. Stabilization with nano has been widely used. However, the procurement of nanomaterials is very expensive. Therefore, this paper will explain the effectiveness of micromaterials when compared to nanomaterials. The main focus that will be discussed in this paper is how the comparison of plasticity index (PI) values between micromaterials and quicklime nanomaterials on expansive soils. The research was conducted at the Bandung State Polytechnic Laboratory. This research uses a stabilization method by adding 2% lime per particle size. The procurement price of nanomaterial was Rp. 2,500,000 and micromaterial was Rp. 1,500,000. The plasticity index (PI) test results obtained are the original soil is 35.68%; mixed soil 2% micromaterial lime is 11.51%; and mixed soil 2% nanomaterial lime is 7.62%. The results of PI values < 12 both include low expansive, so the more effective result is the PI condition of adding 2% micromaterial lime with the procurement of cheaper prices.
