Performance and Formulation Optimization of Mortar Additives

Dry-mix mortar is a pre-mixed building material composed of cement, sand, fillers, and various additives blended in scientifically determined proportions. At the construction site, it only requires adding the appropriate amount of water according to the specified ratio and mixing before use. Additives are a crucial component in dry-mix mortar, determining its performance and applications.

Dry-mix mortar additives come in diverse types, including: water-retaining thickeners, polymers, earlyaccelerators, thixotropic agents, water-reducing agents, synthetic fiber, water-repellents, and other functional additives. The scientific selection and application of additives are key to enhancing mortar performance.

Due to its scientifically balanced formulation, dry-mix mortar can be used for thin-layer bonding, protection, and decoration. Its high efficiency, low pollution, and versatile applications make it a mainstream development direction worldwide.
