   硬化地坪 的耐磨度和抗压能力。 The subgrade of concrete with substandard strength will directly affect the abrasion resistance and compression resistance of the hardened floor . 混凝土基面施工时,由于各种各样的原因,经常会出现混凝土强度不达标的情况,严重影响地面的使用,大大缩短混凝土使用年限。 During the construction of the concrete base, due to various reasons, the concrete strength often fails to meet the standards, which seriously affects the use of the ground and greatly shortens the life of the concrete. The following editors will analyze the causes and preventive measures for everyone.


First, the reason for the insufficient strength of the concrete base

1. The concrete base surface is not compacted when vibrating

2. Imbalance of concrete ratio, inaccurate measurement, or random addition of water during construction, resulting in a large increase in water-cement ratio;

3. The cement used for construction has passed the shelf life or has been affected by moisture; improper cement ratio, large sand content, and large amounts of debris caused excessive voids; improper use of additives and inaccurate addition

4. The mixing time of the concrete base material is insufficient, the mixing is uneven, or the feeding order is reversed;

5. Construction in winter, dismantle the mold prematurely, or freeze early.

6, improper curing of the concrete base, no curing agent or water, or the number of days of curing.

Control measures

1. Ensure that the quality of the cement is clear and within the shelf life.

2. Strictly control the proportion of sand and stone to ensure the mud content and the proportion of concrete.

3. To prevent early freezing of the concrete base, do anti-freezing work before construction.
