混凝土界面剂施工工艺

Construction technology of GJ-302 concrete interface agent

一、新老混凝土连接施工：

First, new and old concrete connection construction:

1、砂浆配置：按照-302混合胶液：水：水泥：黄砂=1 : 1 : 3 : 4的比例进行混合搅拌。

1, according to the -302 configuration: mortar mixed glue: water: cement: sand =1: 1: 3: 4 ratio of mixing.

2、基层拉毛：用刷子或扫帚等工具将搅拌好的混合胶液砂浆甩刷在基层上，拉成粗糙面，硬化后即可进行抹灰施工。

2, grassroots napping: with brush or broom tools such as mixing the glue mortar good throwing brush at the grass-roots level, pull into the rough surface, hardening can be carried out after plastering construction.

3、参考用量：约0.3kg/m2。

3, reference amount: about 0.3kg/m2.

二、混凝土起砂基层处理：

Two, concrete sand base treatment:

1、砂浆配置：按照-302混合胶液：水泥：黄砂=1 : 1-2 : 1-2 的比例进行混合搅拌。

1, according to the -302 configuration: mortar mixed glue: cement: Sand: =1 1-2: 1-2 ratio of mixing.

2、清除已经脱落或疏松的灰砂，将混合胶液用水稀释1-2倍后，涂刷在起砂基层上，使胶液较大限度地渗透进入基层。

2, have clear off or loose sand, mixed glue diluted 1-2 times after brushing in sand base, make the glue effectively penetrated into the base.

3、将配置好的混合砂浆在起砂部位刮涂1-2遍后，洒水泥压光，按照正常的抹灰施工进行养护。

3. After the mixed mortar is scraped for 1-2 times in the sanding position, the cement is sprinkled with cement, and the maintenance is carried out according to the normal plastering construction.

5、参考用量：每道工序用量约0.2kg/m2，修复层厚度不同用量会有变化。

5, reference dosage: the dosage of each process is about 0.2kg/m2, and the different thickness of the thickness of the repair layer will change.
