(針對新混凝土或新水磨石基面)
養(yǎng)護(hù)期:28天以上,底層做過防水處理
粉光強(qiáng)度:300PSI(210kgf/cm 或C25)以上
含水率:8%以下
相對濕度:55%以下

The requirements of the raw floor before construction
(For the fresh cement or terrazzo ground)
Maintaining period: over 28 days and no water any more (except the
ground above the first floor)
Concrete strength: above 300PSI(210kgf/cm2 or C25)
Free water/cement ratio: under 8%
Relative humidity: under 55%
Level degree: within 2~3mm/2M
氣候條件
空氣濕度高于85%時,或氣溫在50℃以下,應(yīng)避免施工。或改用其它低溫耐濕產(chǎn)品。
Clim ate conditions
To avoid the surface of the floor dimming, whitening or not easy to
dry, the construction shouldn`t be performedin the following
conditions: rainy day、the air relative humidity above 85% or
temperature under 10 degree. Another anti-low temperature and
moisture-resistant material is alternative under the frustrated
construction conditions.
場地準(zhǔn)備
施工現(xiàn)場須清走所有雜物,最好避免交叉施工、禁止無關(guān)人員出入。
Ground preparation
Cleaning all the sundries in the construction field; Avoiding cross
construction; Prohibiting all the irrelative from entrancing in.
地面預(yù)處理
地面如有少數(shù)地方潮濕,施工必須用瓦斯槍強(qiáng)制干燥;如有油污等,需用專用洗滌劑作清潔處理。
Ground pre-processing
If there are few damp spots, heating the ground with the gas-sprayer
to make them dry. If there are oils, the special detergent should be
used to clean.
