3. Effect of carbonic acid water on the degradation of Portland cement paste: corrosion process and kinetics

Author

Yin, Su-hong, Yang, Yong-feng, Zhang, Tong-sheng, Guo, Gao-feng, and Yu, Fang

Subjects
Portland cement -- Analysis -- Chemical properties, Steel -- Corrosion, Cement -- Analysis -- Chemical properties, Business, Construction and materials industries
Abstract

ABSTRACT Underground concrete structures usually suffer from carbonic acid water corrosion, thus evaluation and prediction of the carbonic acid water corrosion are very important for cement-based materials. Portland cement pastes [...]

4. Influence of OPC replacement and manufacturing procedures on the properties of self-cured geopolymer

Author

Suwan, Teewara and Fan, Mizi

Subjects
Portland cement -- Analysis -- Chemical properties, Fly ash -- Analysis -- Chemical properties, Polymers -- Analysis -- Chemical properties, Business, Construction and materials industries
Abstract

ABSTRACT Geopolymer typically achieves its strength by heat curing, which is a limitation for in-field applications. This study develops self-cured technologies for fly ash-based geopolymer curing in ambient conditions without [...]

5. The effect of limestone on sodium hydroxide-activated metakaolin-based geopolymers

Author

Cwirzen, Andrzej, Provis, John L., Penttala, Vesa, and Habermehl-Cwirzen, Karin

Subjects
Portland cement -- Analysis -- Chemical properties, Aluminum silicates -- Analysis -- Chemical properties, Business, Construction and materials industries
Abstract

ABSTRACT Blends of metakaolin and limestone can be alkali-activated with NaOH to form solid binders, which show relatively low strength but offer potential as a model system by which the [...]
