It consists of a mixture of finely ground, non-metallic, inorganic components. After adding water to the cement, a suspension (cement paste) is formed, which solidifies and hardens both in air and under water due to the onset of a hydration reaction and remains permanently solid.
This cement is a hydraulically hardening binder for the production of concrete and mortar.a1 ist an ordinary Portland cement composed mostly of clinker which is produced and monitored according to PNS 07.

Production of Portland cement clinker
Limestone, marl, clay or their natural mixture, are required for the production of Portland cement clinker. These starting materials are mined in quarries, pre-crushed and transported to the nearby cement works. There they are homogenized into an intermediate product, with additional natural or secondary corrective substances being added to fine-tune the chemical composition. In the subsequent heating process, the Portland cement clinker is produced from the intermediate product. The firing process takes place in a rotary kiln, where the material is thermally converted at around 1450 °C and then rapidly cooled. The finished clinker is stored in silos.
Cement Production
To produce the ready-to-sell cement {name}, the cement components are finely ground and combined. A sulfate carrier is added to control the setting behavior.
The Davao plant is ISO 9001 certified.

Herstellung Portlandzementklinker
Für die Herstellung des Portlandzementklinkers werden Kalkstein, Ton oder ihr natürliches Gemisch, Kalksteinmergel benötigt. Diese Ausgangsstoffe werden in Steinbrüchen abgebaut, vorzerkleinert und zum nahegelegenen Zementwerk transportiert. Dort
werden sie zu einem Zwischenprodukt homogenisiert, wobei für die Feinabstimmung der chemischen Zusammensetzung weitere natürliche oder sekundäre Korrekturstoffe hinzugefügt werden können. Im anschließenden Brennprozess entsteht aus dem
Zwischenprodukt der Portlandzementklinker. Der Brennprozess findet in einem Drehrohrofen statt, wo das Material bei ca. 1450 °C thermisch umgewandelt und anschließend rasch abgekühlt wird. Der fertige Klinker wird in Silos eingelagert.
Zementproduktion
Für die Herstellung des verkaufsfertigen Zements a1 werden die Zementkomponenten fein aufgemahlen und zusammengeführt. Zur Regelung des Erstarrungsverhaltens wird ein Sulfatträger zugegeben.
Das Werk Davao ist zertifiziert nach ISO 9001.
