Abstract:
—This study investigates the performance evaluation of
lime-cement mortar comprised of manufactured sand and
offshore sand as the river sand alternatives. The most common
mortars suggested by the standards such as S and N types were
selected and five mixes were prepared for each type. Different
sand compositions such as river sand alone, manufactured sand
alone and blended sand with manufactured sand and offshore
sand were used in the mixes. The performance of mortars with
sand replacements were investigated based on the fresh and
hardened properties. The experimental results were undergone
for one-way analysis of variance (ANOVA) test to check whether
the selected sand types and replacements statistically and
significantly impacted the properties of mortar. Results
revealed that the selected replacements statistically and
significantly influenced the workability, compressive strength
and flexural strength while no significant improvements were
noticed with the workable life of mortars. Mortars with blended
sand considerably improved the performance against capillary
water absorption than mortar with river sand.
