为了确保混凝土拌合物有足够流动性及利于施工，建议混凝土加适当外加剂。

金刚砂耐磨地坪是将金刚砂材料均匀地撒布在初凝阶段的混凝土表面，经整体固化后与混凝土地面形成一个密实整体、**硬化面层，抗压、抗冲击、耐磨损且具有高精密度性和着色的高性能耐磨地面。与混凝土地面一起施工，缩短工期，无需施工砂浆找平层。因而对基层混凝土的处理要求很高，而且基层处理的成败也关系到金刚砂耐磨地坪施工质量的好坏!

　　金刚砂耐磨地坪对混凝土基层处理的要求很重要，具体我们可以从以下几个方面做：

　　◇ 基层混凝土强度要求达到C25以上，水灰比控制在0.50以下，混凝土坍落差应控制在70-100mm，混凝土拌合物尽量减少离析并对泌水有所控制。

　　◇ 为了确保混凝土拌合物有足够流动性及利于施工，建议混凝土加适当外加剂。

　　◇ 基层混凝土应参照优良混凝土的标准进行浇筑和振实，注意尺寸精确并减少浮浆产生。

　　◇ 硬化剂表面**同混凝土结构层同时施工，如须同找平层同时施工，建议找平层混凝土采用细石混凝土，厚度不低于50mm，并考虑配置伸缩钢筋网。

　　◇ 特别注意基层混凝土施工块的边角部位，保证该处混凝土振捣密实，并应采取额外加强处理。

In order to ensure there is enough concrete mixture fluidity and conducive to the construction, the proposed concrete with appropriate additives.

Emery wear-resistant floor emery material is spread evenly in the initial setting stage of the concrete surface, after curing and overall concrete floor form a dense overall, super-hardened surface layer, compressive strength, impact resistance, wear resistance and has a high precision and high performance wear colored ground. Construction and concrete floor together, shorten the construction period, no construction mortar leveling layer. Thus the high processing demands of grassroots concrete, and the success or failure of primary treatment is also related to the quality of the floor construction Emery wear bad!

Emery wear floor on concrete base processing requirements are very important, particularly we can do from the following aspects:

◇ grass-roots strength of concrete required to achieve more than C25, water-cement ratio control in 0.50, the gap should be controlled in concrete collapse 70-100mm, concrete mixture to minimize segregation and bleeding has been controlled.

◇ In order to ensure that the concrete mixture has enough liquidity and conducive to the construction, the proposed concrete with appropriate additives.

◇ grassroots excellent reference standard concrete should be pouring concrete and tap, pay attention to the precise size and reduce the floating pulp production.

◇ hardener surface is preferably constructed with concrete structure layer, such as a leveling layer shall be constructed with recommended leveling layer of concrete with fine aggregate concrete, thickness not less than 50mm, and consider configuring retractable steel mesh.

◇ special attention to grassroots corner site concrete construction blocks, ensure HERE compacting concrete vibrators, and should take additional strengthening process.
