Cemex supplied more than 20,000 cubic meters of tailored-made concrete for the City of Archives in Oaxaca, Mexico.
This six-building project was created to rescue, restore, digitalize, and distribute historical documents from the state of Oaxaca.
The City of Archives is the second-largest repository of documents in Mexico, after the General Archive of the Nation.
This complex comprises 16,000 linear meters of special shelves that safeguard documents concerning several of Mexico’s greatest historic figures.
From this project’s conception, architect Ignacio Mendaro Corsini established that all of the structure elements should remind and honor the Mixtec Oaxacan culture. This required changing the traditional grey color of concrete to typical adobe.
The project managers involved Cemex to achieve such a specific color. Cemex performed over 20 tests, varying the quantities of inputs used (coloring, gravel, and sand) until the tone that met the project’s exacting requirements was found.
Cemex also took into consideration the effect that additional procedures, such as the curing, could have on the product’s final color. The mix was complemented with Hidratuim, a self-curing concrete that offers great competitive advantages by replacing concrete’s traditional curing process.
“We received timely assistance from Cemex’s team in Oaxaca and Monterrer – ranging from lab and behavioral assessments to concrete’s mechanical features, even considering changes to the pouring timetable,” said engineer and architect Alberto Orozco Pintos, work superintendent, Pagasa Construcciones.
