Possibilities of Using Plasticizers in Alkali-Activated Systems

The goal of this study is to evaluate the suitability of plasticizer and find the convenient dose of this admixture, which improve the workability and mechanical properties of alkali-activated slag. The stability of plasticizing admixture in alkali environment was studied by infrared spectroscopy (FTIR).

Comparison of Three Plasticizers in Carbonate-Activated Slag

Alkali-activation technology has shown the potential of converting solid aluminosilicate materials into green cement, also known as alkali-activated cement (AAC) and geopolymer, in terms of fewer CO2 emissions and lower energy requirements compared to ordinary Portland cement (OPC) [1].

has been shown that use of slag in construction has a favor-able effect on the strength and endurance of concrete due to slag capacity for pozzolanic action [26 – 28]. The possibility is studied in the present work of using geopolymer based on activated slag as an alternative binder for refractory concrete. Use of such an industrial subsidiary

Efficiencies of Super-Plasticizer on Rheology Properties of

The reaction of alu-mino-silicate materials in a strong alkaline environment results, first of all, in a breakdown of Si-O-Si bonds; later, new phases arise and the mechanism of their formation seems to be a process that includes a so-lution (“synthesis via solution”).

Granulation–Carbonation Treatment of Alkali Activated Steel

The relationship between flexural and compressive strength of the concretes assessed is higher than the recommendation of ACI 31808 and the Australian standard AS3600 (Bernal et al. 2012e), suggesting that adopting design criteria used for Portland cement-based concretes when using alkali-activated slag concrete leads to a conservative design
