Zeolite for Stucco & Mortar Production

Zeolite is an environmentally friendly material for use in cement mixes. Natural zeolite has been shown to improve the strength and durability of mortar mixtures.


A significant amount of carbon dioxide emissions are generated during the production of Portland cement. To locate environmentally friendly alternatives, the scientific community has examined how natural zeolites might serve as supplementary material in cement mixes. For example, Najimi tested the mechanical and durability properties of concrete made with 15 percent and 30 percent of natural zeolite and tested them against mixes without natural zeolite. The results demonstrated that zeolite concrete mixes were effective in regards to water and chloride penetration, corrosion rates, and drying/shrinkage of concrete. Overall, it was found that the incorporation of 15 percent natural zeolite is an appropriate option to improve the strength and durability properties of concrete.

To study the properties and behavior of cement mortar with clinoptilolite, Bilim prepared six mortar mixtures that replaced Portland cement with 0%, 5%, 10%, 15%, 20%, and 30% zeolite by weight. The results indicated that the strength values (compressive and flexural strength) of the mortars containing clinoptilolite were higher than the control mixture. The researcher also observed a decrease in water absorption and porosity of mortars containing zeolite. Also, the freeze-thaw resistance of the mortars containing 5 percent clinoptilolite was higher than the control mortar. Bilim concluded that clinoptilolite incorporated mortars show durability and can lead to considerable economic benefits.

Janotka and Mojumdar conducted a study to characterize sulfate resistance of mortars made from Portland cement and Portland–pozzolan cement with 35 wt% of zeolite addition-zeolite based cement (ZBC). The two types of mortars were tested in water and a 5 percent sodium sulfate solution for 720 days. Results indicated that the sulfate resistance of zeolite is markedly higher than that of Portland cement.
