Engineering Properties of Cement Mortar with Hwangtoh and Fly Ash

This study is performed to evaluate the engineering properties of cement mortar with hwangtoh and fly ash The absorption ratio is in the range of $5.22{\sim}13.16%\;and\;8.53{\sim}13.29%$ at the curing age 14 and 28 days, respectively. The compressive strength is in the range of $92{\sim}458kgf/cm^2\;and\;88{\sim}316kgf/cm^2$ in water and dry cruing at the curing age 28days, respectively. The bending strength and dynamic modulus of elasticity are shown in similar tendency in water and dry curing.
