為了確保混凝土拌合物有足夠流動性及利于施工，建議混凝土加適當(dāng)外加劑。

金剛砂耐磨地坪是將金剛砂材料均勻地撒布在初凝階段的混凝土表面，經(jīng)整體固化后與混凝土地面形成一個密實整體、**硬化面層，抗壓、抗沖擊、耐磨損且具有高精密度性和著色的高性能耐磨地面。與混凝土地面一起施工，縮短工期，無需施工砂漿找平層。因而對基層混凝土的處理要求很高，而且基層處理的成敗也關(guān)系到金剛砂耐磨地坪施工質(zhì)量的好壞!

　　金剛砂耐磨地坪對混凝土基層處理的要求很重要，具體我們可以從以下幾個方面做：

　　◇ 基層混凝土強度要求達(dá)到C25以上，水灰比控制在0.50以下，混凝土坍落差應(yīng)控制在70-100mm，混凝土拌合物盡量減少離析并對泌水有所控制。

　　◇ 為了確�；炷�土拌合物有足夠流動性及利于施工，建議混凝土加適當(dāng)外加劑。

　　◇ 基層混凝土應(yīng)參照優(yōu)良混凝土的標(biāo)準(zhǔn)進(jìn)行澆筑和振實，注意尺寸精確并減少浮漿產(chǎn)生。

　　◇ 硬化劑表面**同混凝土結(jié)構(gòu)層同時施工，如須同找平層同時施工，建議找平層混凝土采用細(xì)石混凝土，厚度不低于50mm，并考慮配置伸縮鋼筋網(wǎng)。

　　◇ 特別注意基層混凝土施工塊的邊角部位，保證該處混凝土振搗密實，并應(yīng)采取額外加強處理。

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.
