混凝土密封固化剂保定环氧地坪强度不足主要表现为三方面，混凝土强度不够必将伴随有抗渗能力降低，耐久性降低，更重要的会影响结构的承载能力。1、降低结构强度、刚直下降。2、构件变形，变形大到影响正常使用。3、抗裂性差、产生大量宽裂缝。

The insufficient strength of concrete sealant floor is mainly manifested in three aspects. The insufficient strength of concrete will inevitably lead to the decrease of impermeability and durability, and more importantly, it will affect the bearing capacity of the structure. 1, reduce structural strength, straight down. 2, component deformation, deformation to normal use. 3, poor crack resistance, resulting in a large number of wide cracks. 强度不足的原因：

Reasons for insufficient strength:

一、混凝土配合比不当

1. Improper mix proportion of concrete

混凝土密封固化剂配合比是决定强度的重要因素之一，其中水灰比的大少直接影响混凝土强度，其他如用水量、砂率、骨灰比等也影响混凝土的各种性能， 从而造成强度不足事故。

The mix ratio of concrete sealant and solidifying agent is one of the important factors to determine the strength of concrete. The water cement ratio has a direct impact on the strength of concrete. Other factors such as water consumption, sand ratio, cement ratio and so on also affect the performance of concrete, resulting in strength shortage accidents.

1、砂石计量不准和水泥用量不足。

1, the measurement of sand and gravel is not allowed and the amount of cement is insufficient.

2、外加剂使用不当。

2. Improper use of admixture.

3、随意套用配合比。

3, casual use of mix.

4、外加剂掺量不准。

4, admixture dosage is not allowed.

5、用水量加大：较常见的有搅拌机上加水装置计量不准；不扣除砂、石中的含水量；甚至在浇灌地点任意加水等。

5. Increased water consumption: more common mixer on the water device measurement is not accurate; do not deduct the water content in sand, stone; and even in the irrigation site arbitrary water.

二、原材料质量差：

Two, poor quality of raw materials:

1、骨料（砂、石）质量不良：石子强度低；石子体积稳定性差；石子形状与表面状态不良；砂、石中有机杂质含量高、粉尘含量高，砂中云母含量高。

1. Poor quality of aggregate (sand and stone): low strength of stone; poor volume stability of stone; poor shape and surface state of stone; high content of organic impurities in sand and stone, high content of dust, high content of mica in sand.

2、外加剂质量不合格或组成配比不合格。

2, the quality of the admixture is not qualified or the composition proportion is not qualified.

3、水泥质量不良：1水泥安定性不合格；2水泥实际活性低。

3, the cement quality is bad: 1 the cement stability is unqualified; 2 cement actual activity is low.

4、拌合水质量不合格。

4, mixing water quality is not qualified.
