Physical and Mechanical Properties of Cement Mortar with Hwangtoh and Fly ash

This study is performed to examine the physical and mechanical properties of cement mortar with Hwangtoh and fly ash. The unit weight is in the range of $2,068kg/m^3{\sim}2,137kg/m^3$ and $1,899kg/m^3{\sim}2,045kg/m^3$, the compressive strength is in the range o $92kgf/cm^2{\sim}458kgf/cm^2$ and $88kgf/cm^2{\sim}316kgf/cm^2$ and the pulse velocity is in the range o $3,195m/s{\sim}4,255m/s$ and $2,670m/s{\sim}3,953m/s$ in water and dry curing, respectively. Also it is decreased with increase of the content of Hwangtoh.
