Properties of Precast Concrete Using Food Industry-Filtered Recycled Diatoms

Abstract
Experimental study on vibro-pressed precast concretes (e.g., pipes) where part of the Portland cement is replaced by natural diatomite and recycled diatomites from beer/wine filtration, both uncalcined and calcined. Mechanical strength, capillary absorption, carbonation, and chloride ingress were assessed. The results show industrial feasibility of both natural and recycled diatomites, with potential improvements in long-term properties; calcination enhances performance versus uncalcined material.
