Effect on Consistency and Anti-Sagging Properties of Cellulose Ethers in Mortar

The consistency and anti-sagging performance of mortar are very important indicators. The mortar must be easy to apply, at the same time with the appropriate consistency and no sagging while applying as thick mortar. Same properties are required in tile adhesive, which can help to support heavy bricks perpendicular to the wall. The testing method of consistency- International standard EN 1015-3 fresh mortar test methods … Continue reading

Application of Starch Ether in Cement- Based Products

Starch ethers, specifically starch ether varieties, are used in cement-based systems such as plastering, adhesives, and leveling layer to form functional surfaces both internally and externally. Plastering mortar is used to cover uneven parts of walls. They must have a strong and durable bond to the substrate. The surface of the mortar must become smooth and flat in order to … Continue reading

The Rheology Functions of Starch Ether in Fresh Mortar

A. The rheology properties of starch ether in machine and spray mortar Starch ethers prevent sagging of mortar and enhance pumping properties. They are easy to distribute evenly in mortar because they are of low viscosity, can dissolve fast, change the rheology of the plaster and gave it thixotropy. This shows that when the external force … Continue reading

Cellulosic Fiber

A fiber is a cell which is a typical dead plant cell with two pointed ends, thick skin, and void in the middle. The fibers (cells) are characterized by being thin and long, with spindle-like ends, flexible, and have a certain binding force with each other after interweaving. The fiber cell is empty inside and surrounded by the cell wall which is composed … Continue reading

Aggregate and filler materials used in drymix mortar

During the study of dry mixed mortar, more attention is paid on admixtures and fiber materials, while the roles of aggregate and filler are often ignored. The effect of reasonable combination of aggregates and fillers is often beyond the reach of admixtures. Reasonable gradation can save cost and improve the comprehensive performance of the product. Experiments show that the higher … Continue reading

Inorganic Cementing Materials Used In Drymix Mortar

Cementing materials are substances with a certain mechanical strength, that can bind other bulk materials (such as sand and stones) or block materials (such as bricks and stones) as a whole during the process of gradually changing from a malleable slurry to a solid stone-like solid under physical and chemical action. The cementing material has a long history … Continue reading
