Performance Analysis of Fine Mineral Fillers in Gypsum Plasters

Abstract

This study investigates the influence of limestone powder and silica flour used as fine mineral fillers on the main characteristics of gypsum plaster. Fine mineral fillers were added in various dosages from 2.5% to 20.0%.

Comparison of the Effectiveness of Fine Mineral Fillers in Cement-Based Tile Adhesives

“…Silica flour Silverbond 50 produced by SIBELCO RUSSIA with an average particle size of 43 microns and 99.5% silica content was used as a silica filler. [6] Experimental formulation used to evaluate the efficiency of above mentioned fillers in cement-based tile adhesives is presented in Table 1.…”

“…Silica fine fillers have a number of significant advantages due to their chemical nature which are high water resistance, abrasion resistance, chemical inertness and durability. [5] Low demand for silica fine fillers on the market today is caused by the fact that until recently silica flour was obtained as a minor product of sand quarrying using old-fashioned grinding machinery which resulted in unstable quality. Insufficient number of studies on silica flour impact on dry-mix mortars performance may be another reason.…”

“…However, the interest of researchers in this area is currently increasing. [5][6][7][8][9] The study f˚Cuses on the impact of silica and carbonate fine fillers in various dosages on bulk density, water retention, slip resistance, open time as well as adhesion, flexural and compressive strength of cement-based tile adhesives.…”
