Effect of methylcellulose admixture on the mechanical properties of cement
Methylcellulose addition (0.2 % to 0.8 % by weight of cement) to cement paste was found to increase the tensile strength by up to 72 %, increase the tensile ductility by up to 620 %, decrease the tensile modulus by up to 57 %, decrease the compressive strength by up to 30 %, decrease the compressive ductility by up to 34 %, increase the compressive modulus by up to 17 %, and decrease the apparent coeffcient of thermal expansion (CTE), (390 Pa, 30-35 deg C) from 10x10-6 down to -4x10-6/deg C. The effects on the tensile properties are larger than those on the compressive properties. The apparent CTE at 30-35 deg C and a compressive stress of 390 Pa is decreased by the methylcellulose addition, becoming more negative as the methylcellulose content increases. All mechanical and thermal effects increase monotonically with increasing methylcellulose content.
