    因强度不够而出现的地坪漆施工基面常见问题包括?

    混凝土基面施工时,由于各种原因,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,和大大缩短了混凝土地面的使用年限。而且强度不达标的混凝土基面,也会对环氧树脂地坪漆的铺设和使用造成隐患,并直接影响环氧树脂地坪漆的耐磨系数和抗压强度。

    During the construction of concrete foundation, due to various reasons, concrete strength often fails to meet the standards, which seriously affects the use of the ground and greatly shortens the service life of the concrete ground. And the concrete base surface whose strength is not up to the standard will also cause hidden danger to the laying and use of epoxy floor paint, and directly affect the wear resistance coefficient and compressive strength of epoxy floor paint.

    Testing method for strength of concrete base: rebound tester 

    一、混凝土基面强度不够的原因:

    1. Reasons for insufficient strength of concrete base surface: 

    1、混凝土基面施工时,未振捣密实;

    1. When the concrete base surface is constructed, it is not vibrated. 

    2、混凝土配比失调,计量不准,或者施工中随意加水,导致水灰比大幅增大;

    2. Concrete proportion imbalance, inaccurate measurement, or the construction of arbitrary water, resulting in a large increase in water cement ratio; 

    3、施工用水泥过了保质期,或者受潮;水泥配比不当,含沙量大,杂物多,导致空隙过大;外加剂使用不当,掺加量不准确。

    3. The cement used in construction has passed the shelf life or is damped; the cement proportion is improper, the sediment content is large, the impurities are too much, resulting in excessive voids; improper use of admixtures, the amount of admixture is inaccurate. 

    4、混凝土基料搅拌时间不够,拌合不均匀,或者加料顺序颠倒;

    4. The mixing time of the concrete is not enough, the mixing is not uniform, or the feeding sequence is reversed. 

    5、冬天施工,过早拆除模具,或者早期受冻。

    5, winter construction, early demolition of the mold, or early freeze. 

    6、混凝土基面养护不当,未使用养护剂或者铺水,或者未达到养护天数。

    6. Improper maintenance of concrete base, no curing agent or water spreading, or no curing days.

    二、防治措施:

    Two, prevention and control measures: 

    1、确保水泥质量过关,在保质期。

    1, to ensure cement quality clearance, in the shelf life. 

    2、严格控制砂、石子配比,保证含泥量,以及混凝土配合比。

    2, strictly control the ratio of sand and gravel, guarantee the mud content, and mix proportion of concrete. 

    3、防止混凝土基面早期受冻,施工之前要做好防冻工作。

    3, prevent the concrete base surface from being frozen early, and prevent freezing before construction. 

    三、混凝土基面强度不够的治理:

    Three, concrete base surface strength is not enough Governance: 

    混凝土密封固化剂可以提高混凝土基面40%的强度。并防止混凝土基面在使用期间起砂起尘。

    Concrete sealing agent can improve the strength of concrete base 40%. And prevent the concrete base from blowing up during the use of sand. 

    什么是混凝土密封固化剂?

    What is a concrete seal curing agent? 

    渗透到混凝土里面的化合物与已凝结的混凝土中所含的半水化水泥,游离钙,氧化硅等物质经过一系列复杂的化学反应,产生硬质性物质,这些化合物最终会使混凝土表层的密实度提高,从而提高混凝土表层的强度、硬度、耐磨性、抗渗性等指标。

    Compounds penetrated into concrete and semi-hydrated cement, free calcium, silica and other substances contained in the condensed concrete undergo a series of complex chemical reactions to produce hard substances. These compounds will eventually make the surface of concrete compactness increased, thereby improving the strength, hardness and resistance of the concrete surface. Wear resistance and impermeability. 

    如何发挥作用?

    How to play a role? 

    复杂的化学反应最终产物会堵塞、固封混凝土的结构孔隙,强度的提高带来表面硬度的提高,密实度的提高带来抗渗性的提高。减少水份流动的路径,即减少有害 物质的侵入,从而大大增强了混凝土的抗化学物质的侵蚀能力。所以混凝土表面密封固化剂能带来长久的密封、坚固、耐磨、无尘的混凝土表层。

    The final product of complex chemical reaction will plug and seal the pore of concrete structure. The increase of strength will bring about the improvement of surface hardness, and the increase of density will bring about the improvement of impermeability. Reducing the path of moisture flow, that is, reducing the invasion of harmful substances, thus greatly enhancing the corrosion resistance of concrete to chemical substances. Therefore, the concrete surface sealant solidifying agent can bring long-term sealing, strong, wear-resistant, dust-free concrete surface.
