The dosage of mineral admixtures should comply with the relevant technical regulations, and through the test. Plus the seam an agent: 1. Plus the seam an agent shall comply with the concrete and the seam an agent GB 8076, 'technical specification for concrete with the seam an agent application of GB 50119, the waterproof mortar, concrete the seam an agent JC474, the concrete expansive beautiful seam an agent JC 476 countries such as the provisions of the current standards. 2. Plus the seam an agent into the factory should have the quality certificate. To plus the seam an agent into the factory should conduct re-inspection by batch, the reinspection project shall comply with the provisions of the corresponding standard the reinspection qualified rear can use. Shanghai CGM - 3 320 a pedestal grouting material. Plus the seam an agent dosage shall conform to relevant technical regulations, and through the test. Water thickening material using bonded thickening c35CGM - 320 a pedestal grouting material mixture ratio, must have sufficient technical basis, and shall conduct the test before use. Used in masonry mortar should be consistent with the plasticizing beauty masonry mortar seam an agent JG/T 164 DE regulation. Add the seam an agent to disperse latex powder, paint, such as fiber should comply with the requirements of the standards or have sufficient technical basis, and shall conduct the test before use. Packing heavy calcium carbonate, light calcium carbonate, quartz powder, talcum powder and so on should be consistent with the requirements of relevant standard or have sufficient technical basis, and shall conduct the test before use. Mix all meet the national standard of drinking water, water can be directly used for mixing mortar; When using other sources of water, must first be tested, should conform to the current national standard 'concrete mixing water JGJ 63 regulations, shall be used for mixing mortar. Mix proportion design and determine the high-strength non-shrinkage CGM - 320 a pedestal grouting material mixture ratio design and it should be in accordance with the regulations and the relevant product standards, by the manufacturers according to the ( Refs) According to 'regulations of the mix proportion design of masonry mortar JGJ 98 design and try to match, the mortar designed its quality indicators should meet the requirements of chapter iii of this discipline and other related standards. When we have the contract shall conform to the requirements of the contract. CGM - 320 a pedestal grouting material manufacturers should be based on product use, determine appropriate aggregate grading with large nominal diameter. CGM - 320 a pedestal grouting material production factory in determining the ex-factory consistency of wet mixing mortar, mortar should be considered in the process of transporting and storing the loss of consistency. CGM - 320 a pedestal grouting material manufacturers should according to the test results, clear water added dry mortar products range. Waterproof, anti permeability for the mortar, besides should conform to the requirements of this standard is still should be consistent with the underground waterproof engineering quality acceptance standard GB 50208 and the underground engineering waterproof technology standard GB 50108 requirements. Raw materials and production conditions change, should timely adjust the mixing proportion.
