    密封固化地坪強度不夠表現在哪些地方

    2020-11-15

    混凝土密封固化劑保定環氧地坪強度不足主要表現為三方面,混凝土強度不夠必將伴隨有抗滲能力降低,耐久性降低,更重要的會影響結構的承載能力。1、降低結構強度、剛直下降。2、構件變形,變形大到影響正常使用。3、抗裂性差、產生大量寬裂縫。

    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. 強度不足的原因:

    Reasons for insufficient strength:

    一、混凝土配合比不當

    1. Improper mix proportion of concrete

    混凝土密封固化劑配合比是決定強度的重要因素之一,其中水灰比的大少直接影響混凝土強度,其他如用水量、砂率、骨灰比等也影響混凝土的各種性能, 從而造成強度不足事故。

    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、砂石計量不準和水泥用量不足。

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

    2、外加劑使用不當。

    2. Improper use of admixture.

    3、隨意套用配合比。

    3, casual use of mix.

    4、外加劑摻量不準。

    4, admixture dosage is not allowed.

    5、用水量加大:較常見的有攪拌機上加水裝置計量不準;不扣除砂、石中的含水量;甚至在澆灌地點任意加水等。

    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、原材料質量差:

    Two, poor quality of raw materials:

    1、骨料(砂、石)質量不良:石子強度低;石子體積穩定性差;石子形狀與表面狀態不良;砂、石中有機雜質含量高、粉塵含量高,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、外加劑質量不合格或組成配比不合格。

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

    3、水泥質量不良:1水泥安定性不合格;2水泥實際活性低。

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

    4、拌合水質量不合格。

    4, mixing water quality is not qualified.
