Abstract

Alkali-activated materials are alternative building binders, where secondary raw materials are processed. The possibility of using landfilled waste materials in the building industry increases their potential application in construction practice, and they are therefore subject to extensive research, especially in recent years. This paper briefly summarizes the interesting results of an experiment aimed at verifying the possibility of applying cement by-pass dust (CBPD) in the preparation of alkali-activated materials. The research was focused on the possibilities of using these wastes for the preparation of small elements of garden architecture. This work also briefly summarized the interesting results of an experiment aimed at verifying the possibility of applying cement by-pass dust (CBPD) in the preparation of alkali-activated materials. In the experiment, a mixture of blast furnace granulated slag, fly ash and cement by-pass dust was alkali activated with sodium metasilicate.

Highlights

In the current construction industry, Portland cement and materials based on it still play a major role in the field of binders [1,2]

Summary

Introduction

In the current construction industry, Portland cement and materials based on it still play a major role in the field of binders [1,2]. Many producers of concrete are already looking for alternative binder systems that could replace Portland cement-based materials or considering the possibility that Portland cement could be used at a minimum. Various hybrid cements, ternary binders, alkali-activated systems, and others are slowly beginning to be used [3,4,5]. Hybrid cements are a type of binder that combines the use of small amounts of Portland cement, mineral admixtures, and alkaline activation [3]. Ternary binders are materials based on gypsum binder with pozzolan and exciter (calcium hydroxide, Portland cement) [6,7]. In the preparation of these materials, secondary raw materials are used, most often fly ashes (FA) and slags [4,5,8]
