نویسندگان
چکیده
The construction industry’s high demand for natural resources, combined with the waste generated by agriculture, creates an opportunity circular economy. This experiment used CaCO3 found in scallop shells as ingredient manufacture of fire-resistant materials, replacing gypsum compositions 40% and 50% weight. mechanical compressive strength was estimated both freeze-thaw cycles acid sulfate attacks. cost disposing shell landfills, savings from substitution, payback period relative to amount production were determined. materials decreased 80% when subjected attack. In response attack, they showed a 100% increase during first three weeks decrease thereafter. amounted $46.36 (22.4%) replacement $58.93 (28.4%) 50%. Respectively, return on investment is achieved at 800- 630-per-metric ton produced. difference between costs disposal (in aquaculture) potential using raw material construction) commercialization two industries, serves reference decision-makers, complies economy principles, reducing inputs outputs waste.
