Anhui Yulong New Material Technology Co., Ltd. is an enterprise specializing in water-retaining tackifiers and anti-segregation agents. Our company produces water-retaining tackifiers. This product has excellent water retention, workability, pumpability and adaptability. It can improve the water retention of concrete and mortar, avoid segregation and bleeding; improve the sensitivity of water-reducing agents and improve the anti-sag properties of accelerating agents. Used in the compounding and synthesis of water reducing agents and accelerating setting agents, it can not only improve product performance but also reduce production costs.
Concrete construction of water-based analysis of water retention and adhesive adjustment of concrete adhesion and easyness
(1) variety of external agents should be designed according to engineering The selection of construction requirements shall be determined through experiments and technical and economic comparisons.
(2) Admixtures added to concrete must not cause harm to the human body or cause pollution to the environment. (3) The cement used in concrete mixed with admixtures should be Portland cement, ordinary Portland cement, slag Portland cement, pozzolanic Portland cement, fly ash Portland cement and composite silicon. Salt salt cement, and the admixture's adaptability to cement should be tested and used only after meeting the requirements.
(4) The materials used in concrete with admixtures such as cement, sand, stone, admixtures, and admixtures should comply with the requirements of the relevant national standards. When trial-mixing concrete with admixtures, the raw materials used in the project, the mix proportions, and the same environmental conditions as those used in construction should be used. The test items should be determined based on the design and construction requirements, such as slump, change in slump over time, setting time, strength, Air content, shrinkage rate, expansion rate, etc., when the raw materials used in the project or the performance requirements of the concrete change, the trial fitting test should be carried out again.
(5) When using different types of admixtures in combination, attention should be paid to their compatibility and impact on concrete properties. Tests should be conducted before use to ensure that the requirements are met before use. Concrete admixtures are materials that are added during the concrete mixing process and can improve the properties of concrete as required. The selection of the type of admixture should be determined based on the main purpose of using the admixture and through technical and economic comparison.
1. Admixtures must have factory certificates.
2. The dosage must be determined by trial preparation.
3. The proportion of materials is accurate, the allowable error is 2%, and no leakage is allowed.
4. When preparing solutions, the minimum dosage is 50kg. It is strictly prohibited to prepare non-integer solutions to prevent mismatching.
5. Stir the solution in the vat frequently to prevent precipitation and caking.
6. The amount of water used for concrete should be deducted from the amount of solution.
7. The solid additives are pre-weighed according to the required amount of each vat of solution and packaged in plastic bags for later use.
8. The storage of admixtures shall be carried out according to the product instructions. It should be strictly distinguished from other easily confused materials and marked.
9. Each time a solution is prepared, a weighing record must be made for verification.
10. All measuring instruments must pass metrological verification.
