1. The influence of different construction conditions
The construction conditions of premixed mortar are varied, including factors such as temperature, humidity, and construction site, which will affect the use of water retaining agent. In a high temperature environment, the evaporation rate of water in the mortar is accelerated. At this time, the amount of water retaining agent needs to be appropriately increased to ensure that the mortar maintains sufficient moisture during the construction process to avoid excessive drying and affecting the construction quality. In a low temperature environment, the setting time of the mortar may be prolonged, and the effect of the water retaining agent is relatively stable, but the amount needs to be adjusted according to the actual situation to prevent excessive water retention from causing slow development of mortar strength.
In a high humidity environment, due to the high moisture content in the air, the moisture of the premixed mortar itself evaporates relatively slowly. At this time, the amount of water retaining agent can be appropriately reduced to avoid the mortar being too wet and affecting its adhesion with the base. On the contrary, in a low humidity environment, water is lost quickly, and water retaining agent should be added to maintain the workability of the mortar.
2. Requirements for different construction sites
For wall plastering construction, due to the vertical wall and large area, the mortar is easy to flow and lose water. In this case, the addition of water retaining agent should ensure that the mortar has good cohesiveness and water retention, and prevent hollowing, cracking and other problems. The amount and type of water retaining agent can be adjusted according to the material and roughness of the wall.
When the ground mortar is constructed, the pressure is relatively large, and the water retaining agent is required to ensure the moisture without affecting the strength and durability of the mortar. For different ground bases, such as concrete base, cement mortar base, etc., the use of water retaining agent will also be different. For example, when constructing on a loose base, more water retaining agent may be required to improve the adhesion between the mortar and the base.
3. Response to special construction conditions
Under some special construction conditions, such as outdoor construction with strong winds and fast construction to meet deadlines, the use of water retaining agent also needs to be adjusted accordingly. In a windy environment, the moisture in the mortar is easily blown dry, and the amount of water retaining agent should be increased and appropriate windproof measures should be taken. When the deadline is met, it may be necessary to use a high-efficiency water retaining agent to ensure that the mortar maintains good workability in a short period of time without affecting its strength development.
Under different construction conditions, the use of Water Retaining Agent For Ready-Mixed Mortar needs to be adjusted according to the specific situation. Construction personnel should fully understand the impact of various construction conditions on water retaining agents, and determine the most appropriate amount and use of water retaining agents through experiments and experience accumulation to ensure the construction quality and performance of ready-mixed mortar.
