Laser scabbling of mortars [PDF]
Construction and Building Materials, 2016 Laser scabbling of concrete is the process by which the surface layer of concrete may be removed through the use of a low power density laser beam. Previous research has suggested that the driving force responsible for laser scabbling is developed within the mortar.

High-Performance Grouting Mortar Based on Mineral Admixtures
Advances in Materials Science and Engineering, 2015 A study on high-performance grouting mortar is reported. The common mortar was modified by mineral admixtures such as gypsum, bauxite, and alunite. The effects of mineral admixtures on the fluidity, setting time, expansion, strength, and other properties

RESISTANCE OF MORTARS WITH GYPSUM, LIME AND COMPOSITE BINDERS AGAINST MOLDS
Acta Polytechnica CTU Proceedings, 2019 Resistance of three mortars (the lime mortar, the gypsum mortar and the mortar with the composite binder) against molds was evaluated. Mortars were also compared according to their pH, bulk density, strength and porosity. Experiments showed that the lime
