Effect of Fine-Ground Ceramic Admixture on Early Age Properties of Cement Paste

Popis výsledku v původním jazyce

Properties of cement pastes with fine-ground ceramics used as an alternative binder replacing Portland cement up to 20% of its mass are investigated. At first, the particle size distribution of cement and fine-ground ceramics is measured using laser analyser. Then, the material properties are studied in the early hardening period up to 28 days. The hydration process of studied materials is monitored by electrical conductivity measurement using TDR sensors. The changes of materials' structures within thehardening are observed using pore size distribution measurement. The compressive strength measurements are done as well. Experimental results show that the replacement of Portland cement by fine-ground ceramics in the amount of up to 20% by mass is acceptable solution from the mechanical point of view. On the basis of measured pore size distribution curves one can also assume similar physical properties of designed materials to the reference material with only Portland cement as binder.
