Metakaolin as a radon retardant from concrete
Radiation Protection Dosimetry, 2003Granite aggregates are known to be the radon source in concrete. Recently, metakaolin has been introduced as a partial substitution of Portland cement to produce high strength concrete. It can effectively reduce the porosity of both the matrix and the aggregate/paste transition zone, which suggests its ability to retard radon emission from concrete ...

Construction and Building Materials, 2019
Abstract The influences of rice husk ash (RHA) on the reaction kinetics, mechanical property, and microstructure of metakaolin-based geopolymer (MG) were investigated. Geopolymer pastes containing different contents of RHA were prepared by sodium silicate activation.

Metakaolin-Based Porous Geopolymer with Aluminium Powder
Key Engineering Materials, 2014Porous concretes such as aerated and lightweight concretes are commonly used in construction fields. Lightweight construction materials are used to reduce either the weight or the budget of building structures. Porous concrete production is widely utilised aluminium (Al) powder to increase pores in concrete structures and giving information for porous ...

Antibacterial Metakaolin-Based Geopolymer Cement
2017Geopolymer cement can be used as a ceramic matrix carrier for different applications such as antibacterial materials. In this work, an antibacterial geopolymer cement has been synthesized by loading the organic compound 5-chloro-2-(2, 4-Dichlorophenoxy) phenol also known as “Triclosan” into a geopolymer metakaolin and nano-silica based cement matrix ...
