## Abstract
Abstract Expansive soils are referred to as swelling soils as a result of changes or modifications in the water content in the soil. This study aims to determine how the addition of fly ash affects the value of the expansive soil's free compressive strength as well as how the curing period affects the value of the expansive soil's free compressive strength that has been stabilized with fly ash. Variations of the addition of fly ash were made by 5%, 10%, 20%, and 25% with curing times of 0 days, 7 days, 14 days, and 28 days to see how adding fly ash affected the Free Compressive Strength Value. The value of the Free Compressive Strength increases as fly ash addition is increased in percentage and curing time is extended. The variation of the addition of 10% fly ash with a curing period of 28 days of 31,622 kg/cm2 and 25% with a curing period of 0 days, 7 days, 14 days, and 28 days produced the best compressive strength value. The value of the Free Compressive Strength increases as fly ash addition is increased in percentage and curing time is extended. The variation of the addition of 10% fly ash with a curing period of 28 days of 31,622 kg/cm2 and 25% with a curing period of 0 days, 7 days, 14 days, and 28 days produced the best compressive strength value. The value of the Free Compressive Strength increases as fly ash addition is increased in percentage and curing time is extended. The variant of 10% fly ash addition with a 28-day curing period produced the maximum compressive strength value of 31,622 kg/cm2.
