Changxin Building Materials Technology Development (Tianjin) Co., Ltd. is a manufacturer of "Changxin Building Materials" cement wall sanding treatment materials, mainly producing WallBoss wall hardener and Zhaoming wall concrete agent. Our products are highly praised for their quality, abundant supply, and wide application. We specialize in solving issues such as insufficient strength of cement plaster mortar, and wall sanding and peeling. The WallBoss wall hardener and Zhaoming wall concrete agent from Changxin Building Materials are suitable for the plaster mortar layers and cement products on walls and columns with substandard cement grades, insufficient mortar strength, and leveling layers with sanding and peeling. The materials are easy to apply, requiring only a spray application, and can increase the strength of cement plaster mortar by 10~60% within 1~2 days.

Concrete wall mortar being loose and shedding sand is a common issue. On one hand, this may be due to reasons during the construction process; on the other hand, it could also be attributed to material or environmental factors. To address this problem, we need to conduct a detailed analysis and provide solutions from four aspects.

Improper material selection
Choosing inappropriate materials is one of the common reasons for the concrete wall mortar to be loose, sandy, and crumble. When selecting mortar, we should opt for high-quality, uniformly sized sand, ensuring it is free of impurities. The selection of cement is also crucial; it should be standard-compliant and mixed with mortar in the correct proportions. Additionally, the use of additives is key to enhancing mortar quality, as they can improve the mortar's bonding and crack resistance.
Solutions:
Select sand: Pay attention to selecting well-screened sand and strictly control the content of impurities.
2. Select the appropriate cement: Choose different types of cement based on the wall's requirements to ensure the quality of the cement.
3. Utilize Appropriate Additives: Select suitable additives based on engineering requirements to enhance the stability and adhesive properties of the mortar.
II. Unstandardized Construction Techniques
Improper construction techniques are another reason for the concrete wall mortar being weak and losing sand or chipping. During the construction process, operators may engage in non-compliant practices, such as working too quickly, applying the mortar unevenly, or failing to properly install embedded components. Additionally, inadequate preparation of the wall's base can also lead to weak mortar.
Solution:
Maintain construction speed: Ensure a moderate pace of construction and complete the coating work within the specified material time.
2. Evenly Apply: Ensure the mortar is applied evenly to avoid uneven thickness.
3. Surface Preparation: Thoroughly clean and treat the wall to ensure the flatness and roughness meet the requirements.
4. Note the installation of embedded components: During construction, pay close attention to the positioning and fixation methods of the embedded components to avoid affecting the mortar.

Section 3: Adverse Environmental Conditions
Unfavorable environmental conditions are also one of the reasons for the concrete wall mortar's lack of cohesion and sanding. For instance, under high temperatures or dry conditions, water evaporates more quickly, which can lead to premature hardening of the mortar; in damp environments, uneven water distribution can easily cause bubbles on the mortar surface.
Solution:
1. Control Construction Environment: In high-temperature or dry conditions, appropriate cooling measures such as misting can be taken. In humid conditions, extend the setting time of mortar to ensure even moisture distribution.
2. Enhance Maintenance Quality: Properly maintain concrete wall surfaces, ensuring timely moist curing to prevent premature evaporation of moisture.
Four: Worker's technical qualifications are insufficient
Worker's skill level is also a crucial factor affecting the strength of concrete wall mortar. If workers lack professional training or insufficient experience, issues such as poor construction quality and uneven application are likely to occur.
Solution:
Enhance Technical Proficiency: Train workers to improve their technical skills and operational capabilities, ensuring construction quality.
Enhance Quality Inspection: Establish a comprehensive quality monitoring and acceptance system, and strictly supervise and inspect the construction process.
In summary, there are numerous reasons for the concrete wall mortar to be loose and flake off, including improper material selection, non-standard construction techniques, unfavorable environmental conditions, and insufficient worker skill levels. However, by choosing the right materials, adhering to standardized construction methods, ensuring favorable environmental conditions, and employing highly skilled workers, we can address this issue and guarantee the quality and stability of the wall mortar. Only then can we construct durable and robust concrete walls.
