- Unconfined Compressive Strength Equation

Compressive strength test results show that the strength of cement-stabilied soil mixed with seawater is 50 greater than that mixed with freshwater at the 90 th day. With the addition of ultrafine silica fume the unconfined compressive strength increases by close to 6.5 compared with seawater alone at the 90 th day
