Field detection method and detection device for concrete protective material spraying amount

The invention relates to a field detection method for concrete protective material spraying amount. The method comprises steps of pasting multiple pieces of PH test papers in a concrete protective material spraying area uniformly; spraying a concrete protective material; and determining whether the concrete protective material spraying amount reaches the standard according to color change of the PH test paper. In the method, construction amount of the protective material sprayed in unit area can be determined according to color developing on the PH test paper when the protective material is sprayed onto the PH test payer on the construction site by using the characteristic of an inorganic osmotic crystalline aqueous solution, so as to determine whether the protective material reaches design requirements. The invention further relates to a detection device for detecting spraying amount of the concrete protective material on the site. 本发明涉及一种混凝土防护材料喷涂量现场检测方法，包括在一个混凝土防护材料喷涂区域内，均匀地粘贴多个酸碱试纸；实施混凝土防护材料喷涂；根据酸碱试纸的颜色变化
