Abstract The blended Portland cement, CEM II, is obtained by replacing a part of clinker by an addition, as described in the EN 197-1 standard. Among the materials cited in this standard, there are the artificial pozzolans. When used as partial replacement of clinker or cement and in presence of water, the pozzolanic materials react with the calcium ...

Abstract This paper describes the effect of high temperature on the hydration characteristics of artificial pozzolanic cement pastes containing metakaolin with or without silica fume for different hydrothermal ages in well closed stainless steel capsule. Pastes were hydrothermally treated in well closed stainless steel capsule at 180 °C for different

Metakaolin is a supplementary cementitious material with pozzolanic properties. Its precursor, kaolin, does not occur in natural conditions as a pure phase but is often mixed in various proportions with many secondary minerals. Two natural clays from the same deposit, mainly composed of kaolinite and quartz have been burnt at a suitable temperature and

Effect of Artificial Pozzolans on Capilarity and Compressive Strength of Self Compacting Concretes
2014Bu çalışmada iki farklı yapay puzolanın kendiliğinden yerleşen betonlarda kapilarite ve basınç dayanımına etkisi araştırılmıştır. Çalışmada yapay puzolan olarak uçucu kül ve yüksek fırın cürufu %20,%40 ve %60 oranında çimentoya ikame edilerek kullanılmıştır.
