2018-03-19
The use of sodium gluconate in concrete engineering has strict standards, and the use in engineering construction is under the condition of scientific configuration, with scientific and reasonable requirements to produce and deploy. Only in accordance with the standard usage to use, in order to play the role of sodium gluconate in various engineering construction, in order to play a better effect.
The use of sodium gluconate in concrete engineering has strict standards, and the use in engineering construction is under the condition of scientific configuration, with scientific and reasonable requirements to produce and deploy. Only in accordance with the standard usage to use, in order to play the role of sodium gluconate in various engineering construction, in order to play a better effect. Less than standard usage, or more than standard usage, will have a more or less reduction in performance or effect.
In ordinary concrete engineering, the standard usage is generally between 0.05 and 1.0, and in general, more than the 0.7 usage of concrete in the performance of the other have a certain weakness. At a temperature of 20 ℃, the amount of use for a few hours is 0.075; at a temperature of 20 ℃, if you want to achieve more hours, the recommended amount is 0.15; and at a normal temperature of 20 ℃, To achieve the retarding effect within 2 days, the standard amount of mortar concrete admixture is 0.25.
In the case of high temperature, similar to oil well operations, similar to 170 ℃ high temperature, concrete is easier to solidify, but also more prone to cracks and other problems, so you need to use more, in order to achieve the desired retarding effect, generally in this case the amount of use is 1.00, and the amount of use required to configure super-strength plasticizing concrete is 1.00,. In daily life, the amount of normal plasticizing requirements is generally 0.05, which can basically meet the requirements of our basic construction of concrete retarder. However, the specific use of specific circumstances, in the special needs of the environment, it is necessary to use the amount of special requirements.
