Estimating UCS of cement-grouted sand using characteristics of sand …
The results demonstrate that UCS of grouted sand can be expressed as the power function of the UCS of cured pure grout: UCS grouted sand / 1 MPa = A soil ᆞ(UCS pure / 1 MPa) N. Because the exponent N strongly depends on the combination of pore area and pore size, N is expressed as the function of porosity (n) and specific surface (S a ).
