Seek information on the construction techniques for acid-resistant floors and foundation treatment methods

There is information available online. 1. Construction preparation: Familiarize oneself with the drawings and specifications, conduct technical briefings, and ensure proper handover from the previous construction stage. Material preparation: The anti-corrosion materials used in this project are stored in appropriate warehouses/locations, and the incoming materials are inspected to ensure they meet the requirements of the HGJ229-91 standard. Tools and equipment required: cutting machine, mixer, grinder, trolley, clay tray, ropes, hoses, shovels, steel trowels, scrapers, rubber mallets, wire brushes, brushes, putty knives, level, straightedge, ropes, plumb bob, small beams, measuring cups, platform scales, tarps, ventilation and lighting equipment, etc. II. Quality Assurance – Requirements at the grassroots level: After the rubber lining layer has been approved upon inspection, it must be cleaned thoroughly and kept clean and dry. Construction environment: The optimal temperature for anti-corrosion treatment is 15–30°C, with a relative humidity of no more than 80%. The amount of curing agent used should be adjusted accordingly to changes in temperature; when the temperature is too low or the humidity is too high, dehumidifiers should be used to regulate the temperature and humidity at the construction site. The construction of anti-corrosion projects is sensitive to water and sunlight, so measures to provide shade and protection from rain must be taken. The preparation of mortar and adhesive must be carried out strictly in accordance with the specified ratios, and it must be used up within the designated time frame; mortar that has begun to set shall not be used. III. Construction Method: Protection of the rubber lining layer and the mortar bonding layer: Before installing the carbon bricks for lining, a uniform layer of mortar with a thickness of δ=3mm is applied on the base plate to protect the rubber lining layer and prevent gaps from forming in the mortar bonding layer; construction is carried out after the mortar has cured at room temperature. Positioning, marking, and preliminary layout: First, a center crosshair is marked based on the dimensions of the groove bottom, after which positioning and marking are carried out. Based on these markings, preliminary layout is done, lines are drawn, cutting is performed, and numbering is applied. Lining procedure: The masonry is carried out from bottom to top, starting with the base before moving on to the walls; at recessed corners, the vertical surface covers the horizontal one, while at protruding corners, the horizontal surface covers the vertical one. Masonry method: The base and walls are all constructed using the grout extrusion method, with masonry carried out row by row, layer by layer, and block by block following the guide lines. Apply the prepared mortar evenly to the three surfaces of the carbon brick (i.e., the back, end, and sides), then press firmly (using a rubber mallet) to compact it, ensuring that the grout joints and the bonding layer are fully filled; remove any excess mortar as it appears. The surface layer should be laid evenly and vertically, with the joints between rows and layers offset from each other. IV. Quality Standards: The entire masonry should be level and straight, with no cross-joints or missing joints present. Flatness is checked using a 2m straightedge, with surface gaps not exceeding 4mm ； The vertical deviation of the groove wall shall not exceed 4 mm ； The adjacent deviation shall not exceed 2 mm ； The joint layers and grout between bricks are full and dense, with smooth and even joints. The slope meets the design requirements, with a deviation of ±0.2% of the slope length. V. Safety Protection: Construction operations must be carried out in strict accordance with safety procedures, and the employer’s factory rules and regulations must be obeyed to ensure safe production and civilized construction practices. Conduct safety training for construction workers prior to work, so that they are aware of the potential for accidents and the methods to handle them ； Those suffering from chronic skin diseases or who are allergic to certain substances should not participate in the construction work. Construction workers must wear safety helmets and soft-soled shoes when entering the site. Workers handling clay should wear gas masks or respirators as well as rubber gloves, and proper ventilation must be ensured at the site. All lighting power supplies, switches, and electric driving devices should be under the supervision of a designated person, and safety inspections must be carried out after storms. Fire extinguishers shall be placed at the construction site; smoking and the use of open flames are strictly prohibited. VI. Project Acceptance: Anti-corrosion projects should undergo intermediate acceptance and final acceptance. Works that have not been inspected shall not be put into use. Quality inspection should follow the principle of combining self-inspection, mutual inspection, handover inspection, and professional inspection. The covered construction areas must undergo intermediate inspections, and records of the inspection for concealed works must be filled out. The completion inspection can only be carried out after all tasks related to each piece of equipment have been finished. The following documents shall be provided for the completion acceptance: factory certificates of conformity for the main raw materials (or their product manuals) and other quality inspection (testing) reports ； Test report on the main technical parameters of corrosion-resistant mortar ； Anti-corrosion project construction record ； Design change notification forms, records of material substitution, and handling of major technical issues ； All records of concealed works ； Completion acceptance form, quality assessment form.
