One of the most significant advantages of redispersible powder is its ability to disperse evenly in water, forming a stable suspension. This characteristic makes it ideal for use as an additive in cementitious systems, where it can significantly improve workability, reduce water demand, and enhance strength development. By incorporating redispersible powder into concrete, builders can achieve higher strengths, better crack resistance, and improved durability, all while using less water.

  • The water retention property of mortar refers to the ability of mortar to retain water. Mortar with poor water retention property is easy to bleed and segregate during transportation and storage, that is, water floats above and sand and cement sink below. It must be remixed before use.
    All kinds of base courses that need mortar for construction have certain water absorption. If the water retention of mortar is poor, as long as the premixed mortar contacts with the block or base course, it will absorb water from the premixed mortar during the mortar coating process. At the same time, the mortar surface will evaporate water towards the atmosphere, resulting in insufficient water for mortar due to water loss, affecting the further hydration of cement, and affecting the normal development of mortar strength, resulting in strength In particular, the interface strength between the hardened mortar and the base course becomes lower, resulting in mortar cracking and falling off. The mortar with good water retention has sufficient cement hydration, and its strength can be developed normally, and it can bond well with the base course.
    The ready mixed mortar is usually laid between the water absorbing blocks or coated on the base course to form a whole with the base. The impact of poor water retention of mortar on project quality is as follows:
    1. Due to excessive water loss of mortar, the normal setting and hardening of mortar are affected, and the bonding force between mortar and object surface is reduced, which is not only inconvenient for construction operation, but also reduces the strength of masonry, thus greatly reducing the project quality.
    2. If the mortar bond is not good, the water is easily absorbed by the bricks, which makes the mortar too dry and thick and uneven. During the implementation of the project, it not only affects the progress, but also makes the wall easy to crack due to drying shrinkage;
    Therefore, increasing the water retention of mortar is not only beneficial to construction, but also can increase the strength.

  • Cellulose is a fascinating natural polymer that plays a critical role in the structure and function of plants. It is the most abundant organic compound on Earth, making up the cell walls of plant cells and providing rigidity and strength to plants. Cellulose is also an important dietary fiber for animals, including humans, and has been used for centuries in various industries, such as paper and textiles.
