Introduction of the guiding dosage of sodium gluconate

2022-04-14

The use of sodium gluconate in concrete engineering has strict standards, and the use in engineering construction is produced and formulated with scientific and reasonable requirements under the condition of scientific configuration. Only when it is used in accordance with the standard usage amount can sodium gluconate play its role in the construction of various projects and achieve better results. Less than the standard usage, or more than the standard usage, will have a more or less reduction in performance or effect.
In ordinary concrete projects, the standard usage is generally between 0.05 and 1.0, and generally speaking, concrete with a usage exceeding 0.7 has a certain weakness in performance in other areas. Under the temperature of 20°C, the usage amount for retarding the setting effect for several hours is 0.075; under the temperature of 20°C, if you want to reach more hours, the recommended usage amount is 0.15; and at the normal temperature of 20°C, it is recommended to use 0.15. To achieve the retarding effect within 2 days, the standard amount of mortar concrete admixture used is 0.25.
In the case of high temperature, similar to the high temperature of 170 ℃ in oil well operations, concrete is more likely to solidify, and cracks are more likely to occur, so more use is required to achieve the required retardation effect. Generally, in this case, the The usage amount is 1.00, and the usage amount required to configure super-strength plasticizing concrete is also 1.00,. Under normal plasticization requirements in daily life, the usage amount is generally 0.05, which can basically meet the requirements of our basic construction projects for concrete retarders. However, the specific use of the specific situation, in the environment of special needs, it is necessary to use the amount of special requirements.
