环氧地坪施工對混凝土基面有什麼要求麼?

环氧地坪施工對混凝土基面有什麼要求麼?1、混凝土基面平整密實,強度條件不低於C20；強度太差,會降低环氧地坪塗層的耐壓、抗沖功能及耐久性；2、地面平整度通常在2M界線內，落差不大於2mm;如落差較大,則环氧地坪砂漿層需加厚以減削落差；3、如需塗裝的地彩色沥清地坪面處於底層,地下水位較高,則混凝土底層應作好防水辦理,防止地下水蒸發頂起环氧地坪塗層而導致起泡、起殼征象；
What are the requirements for concrete base surface in epoxy floor construction? 1. The concrete base surface is smooth and compact, and the strength condition is not less than C20; too poor strength will reduce the compressive, impact resistance and durability of epoxy floor coating; 2. The ground evenness is usually within the 2M boundary, and the drop is not more than 2mm; if the drop is large, the ground mortar layer needs to be thickened to reduce the drop; 3. If the ground to be coated is at the bottom. If the groundwater level is high, the concrete bottom should be waterproofed to prevent the evaporation of groundwater from jacking up the epoxy floor coating and causing blistering and crusting.
4、混凝土徹底幹燥起碼三周以上,含水率不高於6%;且在養護過程中防止淋雨及積水在地面等,不然易導致片面混凝土水分含量超標；
4. The concrete is thoroughly dried for at least three weeks, and the moisture content is not higher than 6%. In the course of maintenance, it is easy to prevent rain and water accumulation on the ground, otherwise the moisture content of one-sided concrete will exceed the standard.
5、樓板上、鋼筋混凝土梁及分次澆鑄的混凝土上的細石，混凝土找平層強度不應低於C20,厚度不低於30mm；
5. The strength of concrete leveling layer should not be lower than C20 and the thickness of concrete leveling layer should not be less than 30mm on floor, reinforced concrete beams and concrete cast in stages.
6、防起殼,混凝土層以及泥漿找平層需一同澆註；假如先搗混凝土層,則條件泥漿層的厚度不低於4cm ,叉車道則條件更厚一些；不起砂,硬度好,沒有水泥粉化征象：
6. Shell-proof, concrete layer and mud leveling layer need to be poured together. If the concrete layer is tampered first, the thickness of mud layer is not less than 4cm, and the condition of forklift lane is thicker. No sand, good hardness and no sign of cement powdering are required.
a 、優質水泥，且標號越高越好；
A. High quality cement, and the higher the label, the better.
b 、新倒水泥泥漿層要充分調養，水泥基面平展、無坎坷不平、蜂窩麻面、水泥疙瘩，地面平展性不大於塗裝。
B. The newly poured cement slurry layer should be fully maintained. The cement base surface is flat, no rough, honeycomb linen surface, cement knot, and the ground flatness is not greater than painting.
7、對損害的混凝土修護,可以采取細石混土壤,強度品級不應小於C20,厚度不應小於30mm。
7. When repairing damaged concrete, fine stone mixed soil can be adopted. The strength grade should not be less than C20 and the thickness should not be less than 30mm.
8、細活部位,如落水管外圍、門坎處等混凝土應平整,棱角處應平直。
8. Fine and flexible parts, such as the periphery of the downspout pipe and the door sill, should be level 环氧地坪and the edges and corners should be straight.
