In recent years, the use of lime mortar has garnered a lot of attention due to its sustainability and its ability to renew old architecture. However, there has been a lack of research on the adhesion between lime mortar and grey brick. To clarify the adhesion of lime mortar and grey brick, we comprehensively investigated a representative sample, which was constructed …
This paper presents the properties of cement mortar with fine eggshell powder as partial replacement of cement. Type-N mortar was prepared with cement: sand: water ratio of 1: 2.75: 0.60 and the percentages of cement replacement tested are 2.5%, 5%, 7.5% and 10% by weight of cement. ... The chemical mechanism of hydration is a complex process ...

This material, called clinker, is ground into a fine powder and packaged to mix with various cementitious building materials, including mortar and concrete. Cement is often called Portland cement, coined by a mason in the 1800s who likened the material's color to stone from Portland's quarries off the coast of England.
Thermal energy storage recycled powder mortar (TESRM) was developed in this study by incorporating paraffin/recycled brick powder (paraffin/BP) composite phase change materials (PCM). Fourier transform infrared and thermogravimetric analysis results showed that paraffin/BP composite PCM had good chemical and thermal stability. The onset melting temperature and …
Chemical activation can enhance the surface activity of brick powder [15], improving the mechanical properties of brick-based cementitious materials, which are typically poor, and enhancing their durability [16].

In order to characterize the marble powder from a chemical point of view, thermal analysis and X-ray diffraction were carried out. Thermal analysis carried out show that the examined material contains about 66% of calcium carbonate, CaCO 3.As a matter of fact, as it can be observed in Fig. 3, a sharp weight loss (corresponding to the flex of the DTA curve) …
In environments where the mortar may come into contact with chemicals, acids, or other corrosive substances, specialty mortars like epoxy mortar may be required due to their high chemical resistance. Aesthetic Considerations: Determine if the mortar's color and texture need to match or complement the surrounding materials.
In order to study the effect of limestone powder as an auxiliary cementing material replacing part of cement on the properties and pore structure of cement mortar, the working performance ...
Cement production has the largest carbon-footprint since it leads to the release of carbon dioxide and enormous energy consumption. Therefore, scientific research is being conducted worldwide on the possibility of using other materials that can be used as a cement substitute. A potential alternative material is glass powder. This paper present research results on the use of glass …
