新建的新锦江饭店是一座五星级宾馆,主楼屋面设有直升飞机停机坪。由于停机坪硬度和耐磨度有着一定要求。故其表面采用由香港W.R.GRACE有限公司生产的DURFAX地面硬化剂(以下简称硬化剂)。该硬化剂是一种1～5mm的灰黑色小颗粒。根据施工说明,硬化剂是在地面混凝土浇捣抹平、表面不再渗水后,按2份硬化剂和一份水泥的比例进行干粉拌和后分撒在混凝土表面上,待混合物渗透后用铁板抹平即可,不同掺量硬化剂的地面硬度效果如下表: 新锦江停机坪选用5kg/m～2这一档,硬化剂在上海还刚刚开始使用,对这种新材料的施工工艺我们也仅仅是在摸索之中。一、工艺流程面层清理(?)绑扎网片(?)浇捣细石混凝土及抹
The new Jin Jiang Hotel is a five-star hotel with a helipad at the main building roof. Because the apron hardness and wear resistance have certain requirements. Therefore, DURFAX surface hardener (hereinafter referred to as hardener) manufactured by Hong Kong W.R. GRACE Co., Ltd. is used on the surface. The hardener is a grayish black small particle of 1 to 5 mm. According to the construction instructions, the hardener is poured on the surface of the concrete, the surface is no longer seepage, after the dry powder mixing according to the proportion of 2 parts of hardener and a cement, spread on the concrete surface, after the mixture infiltration with iron plate Smoothing can be, the ground hardness effect of different amounts of hardener is shown in the following table: The new Jinjiang apron selection of 5kg/m ~ 2 file, hardening agent has just begun to use in Shanghai, the construction process of this new material we also Just trying to find it. First, the process flow surface cleaning (?) lashing mesh (?) pouring concrete fine stone and wipe
