环氧地坪漆是否可以在起砂的旧地面上

2018-11-01 15:27:11 常州市星火铝艺制品有限公司 阅读

起砂的旧地面一定要打磨,如果原地面标号不够打磨也没用,建议再重新水泥浇筑,然后做你需要的环氧地坪环氧地坪材料有多种,可根据你的要求来做,但要听取工程师的意见,要不然会影响使用年限。环氧地坪工程环氧地坪专家意见:工地上常常使用界面剂搅拌水泥进行涂刮,希望将起砂部位覆盖,事实上这样不会达到预期效果,一般情况干燥后表层又会龟裂,剥落,大面积起壳。这是由于基层未处理好的原因,基层起粉,想通过覆盖达到修复的效果是完全错误的想法。

The old ground must be sanded, if the original ground label is not enough grinding is useless, it is recommended to RE-cement pouring, and then do the epoxy floor you need, epoxy floor materials can be done according to your requirements, but to listen to the opinions of the engineers, otherwise it will affect the service life. Epoxy floor engineering experts opinion: the site often use interfacial agents to mix cement scraping, hoping to cover the sand part, in fact, this will not achieve the desired effect, generally dry surface will crack, peel off, large area of shelling. This is because the grass-roots has not been properly treated, the grass-roots flour, want to achieve the effect of repair by covering is completely wrong idea. 1.水灰比过大:即拌合的混凝土水量大,导致混凝土表面泌水,降低混凝土表面强度。

1. Water cement ratio is too large: that is, the mixing of concrete water, resulting in the surface of concrete bleeding, reducing the surface strength of concrete.

2.砂石料的级配不合理、含泥量高:骨料级配不合理、过细的土砂也易导致地面起砂,影响水泥的早期水化及混凝土的凝结。

2. The unreasonable gradation of sand and stone and the high content of mud: the unreasonable gradation of aggregate and the excessive fine sand also easily lead to the ground sand, affecting the early hydration of cement and the setting of concrete.

3.施工过程中的过分振捣:加剧混凝土表面的泌水,导致混凝土表面强度较低。

3. Excessive vibration during construction: aggravate the bleeding of concrete surface, resulting in low surface strength of concrete.

4.养护不当:未能及时养护或养护不充分,暴晒或大风导致混凝土表面大量失水,表面得不到充分水化,导致强度较低。

4. Improper maintenance: not timely maintenance or inadequate maintenance, exposure to sunlight or wind caused a large number of concrete surface dehydration, surface can not be fully hydrated, resulting in low strength.

5.其它原因:压光时间掌握的不好、混凝土表面未达到一定的强度就上人作业、低温下施工混凝土表面受冻等。

5. Other reasons: poor control of calendering time, concrete surface did not reach a certain strength on the work, low temperature construction of concrete surface frozen, etc.
