Investigation of the formation of microstructure and strength characteristics of slag-alkaline arbolite

Abstract

The creation of the slag-alkaline arbolite's structure is examined in this study, which is based on measurements of the deformation of the mortar component, contact zone, and filler. Composites made of slag and alkaline arbolite are among the lightest building materials available, with excellent sound insulation and low thermal conductivity. Standard measuring equipment and procedures for analyzing the chemical and physico-mechanical properties of slag-alkaline arbolite composites were employed during the experimental tests. All of the test samples were light concrete prisms with a cross section of 150x150 mm and a length of 600 mm. For comparison, one portion of the samples was constructed of slag-alkaline Portland cement, and the other portion was made of slag-alkaline binder with crushed cotton stem fibers as an organic component. The durability and deformability of arbolite were tested under Kazakhstan weather conditions and in standard hardening chambers. The arbolite underwent a compression stress that ranged from (0.3 to 0.75) Rbn of prismatic strength. It was discovered that the organic cellulose filler added to the slag-alkaline binder based on crushed cotton stalk fiber, which makes up to 70 % of the volume, has a major impact on the way structures are formed. The system becomes rigid, the elasticity changes, and the acoustic properties in this case will fix both physical and physico-chemical processes when a porous organic filler is added. The acquired results can be applied to the creation of efficient wall materials for civil buildings, including seismic zones
