An investigation on compressive strength of cement mortar with seashell powder additive
In order to improve performances of cement mortar and cost consideration, several alternatives have been selected. Among several of natural additives, seashells have been chosen. This is due to its high percentage of calcium carbonate which contributes to toughness property. Moreover, environment...

| description | In order to improve performances of cement mortar and cost consideration,
several alternatives have been selected. Among several of natural additives, seashells
have been chosen. This is due to its high percentage of calcium carbonate which
contributes to toughness property. Moreover, environmental pollution might occur if
seashells are not properly disposed of. Hence, the potential of seashell powder as an
additive for cement mortar has been investigated. The objectives of this research are to
identify the best compressive strength of cement mortar with acceptable percentages of
seashell powder, to determine modification of modulus elasticity of cement mortar as
well as to investigate the time to failure against force. A total of 30 cubes of cement
mortar samples were prepared with 0%, 1%, 2%, 3% and 4% seashell powder additive.
Cube specimens of 100mm x 100mm x 100mm were moulded and cured for
7th
and 28th
days. After that, the compressive strength of cement mortar samples with seashell
powder additive was tested using Universal Tensile Machine. The results revealed that
the compressive strength of cement mortar with 1% seashell powder additive is higher
than control sample. In term of failure, the cement mortar with seashell powder additive
obtained longer time to failure compared to control sample. In general, seashell powder
has potential become partially substitution of cement and improve performances of
cement mortar. |
