Preparation and Properties of Alkali Activated Metakaolin-Based Geopolymer
The effective activation and utilization of metakaolin as an alkali activated geopolymer precursor and its use in concrete surface protection is of great interest. In this paper, the formula of alkali activated metakaolin-based geopolymers was studied using an orthogonal experimental design. It was found that the optimal geopolymer was prepared with metakaolin, sodium hydroxide, sodium silicate...
متن کاملEffects of Nano-SiO2 on Setting Time and Compressive Strength of Alkali- activated Metakaolin-based Geopolymer
This study presents a discussion on the effects of different solid-to-liquid (S/L) ratios (0.97 to 1.19) and nanoSiO2 (NS) percentages (0% to 3%) on some properties of metakaolin (MK)-based geopolymers. The setting time and compressive strength were investigated. Mercury intrusion porosimetry, fourier transform infrared spectroscopy, and scanning electron microscopy were used to determine the m...
متن کاملALKALI Activated FLY-ASH Based Geopolymer Concrete
Considering the increasing demand for developing alternative construction materials, due to the growing environmental concerns, this paper discusses the feasibility of alkali activated geo-polymer concrete, as a future construction material. The main objective of this study involves observation of structural behaviours of the fresh fly ash-based geo-polymer concrete, understanding the basic mix...
متن کاملStudy of Metakaolin-Based Geopolymer with Addition of Polymer Admixtures
In the present work, metakaolin-based geopolymer including different polymer admixtures was studied. Different types of commercial polymer admixtures VINNAPAS® and polyethylene glycol of different relative molecular weight were used as polymer admixtures. The main objective of this work is to investigate the influence of different types of admixtures on the properties of metakaolin-based geopol...
متن کاملApplication-Oriented Chemical Optimization of a Metakaolin Based Geopolymer
In this study the development of a metakaolin based geopolymeric mortar to be used as bonding matrix for external strengthening of reinforced concrete beams is reported. Four geopolymer formulations have been obtained by varying the composition of the activating solution in terms of SiO₂/Na₂O ratio. The obtained samples have been characterized from a structural, microstructural and mechanical p...
