    水泥混凝土地面起砂的原因
    来源:http://www.jndmzp.com   时间:2016-3-11 16:56:14
    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 large water cement ratio: concrete mixing water is large, leading to the concrete surface bleeding, reduce the strength of concrete surface.
    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 sand and gravel gradation unreasonable, mud containing high amount: aggregate gradation unreasonable, meticulous soil sand also easily lead to the surface of the sand, the effect of cement early hydration and concrete setting.
    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。
    Excessive vibration in the process of Construction: 3 pound increased on the surface of concrete bleeding, leading to the concrete surface strength is low.
    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: failed to timely maintenance or maintenance is not sufficient, or exposure to wind in the surface of the concrete surface of a lot of water loss, without adequate hydration, leading to lower 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: pressure light time to grasp, the concrete surface did not reach certain strength on operation, low temperature construction concrete surface from freezing and other.
    无论是混凝土水泥地面、金钢砂耐磨地面、水磨石地面还是环氧地面,地面经过频繁使用,或由于建造时在材料的选择、施工质量的控制、地面保养等方面不够严格,很容易出现地面开裂、翻砂起尘、伸缩缝崩口、找平层空鼓、涂层起皮脱离等问题。
    Both cement concrete ground, carborundum wearable Floor, terrazzo floor or epoxy floor, ground after frequent use, or due to construction in material selection, construction quality control, ground maintenance is not strict, it is prone to cracks on the ground, foundry from dust, expansion joint collapse mouth, leveling layer Konggu, coating on skin detachment.
