Abstract

The objective of this paper is to compare the chemical composition of portland cement versus calcined mollusk wastes from the city of Chimbote. The type of research was basic, with a descriptive design. The population was all the calcined mollusk waste from the city of Chimbote. The sample was 10 kg of fan, snail and mule's foot shells. Through X-ray fluorescence and energy dispersive spectroscopy (EDS) tests, it was obtained that the main component of the mule's foot mollusk is calcium oxide (99.627%), of the snail is calcium oxide (99.5478%) and of the fan, the shell is calcium oxide (80.755%) and sulfur oxide (12.044%). The cement is composed of a great percentage of calcium oxide (60.00%), silicon dioxide (19.50%) and aluminum oxide (5.00%) which can be replaced by the mollusks studied in this research, but it requires a previous treatment to add the other components of the cement so that it does not lose its properties.
