Abstract
A composite synergist for cement is prepared from sodium hydrogen sulfate (65-85 Wt%), molasses (10-25) and ethanediol (5-10). It is used by proportionally mixing it with the raw materials of cement to improve the grinding efficiency, lower the energy consumption, and increase the output and quality of cement.
Description
(1), affiliated field
What the present invention relates to is a kind of cement additire, specifically a kind of cement additire that is used for cement production process.
(2), background technology
Saying at present the cement additire that uses, is to insert in the use after cement dispatches from the factory, to improve the performance of cement mostly.Powder-grinding process in the cement production process not only needs to consume a large amount of energy, and the bad meeting of grinding effect directly influences the quality of cement.
(3), summary of the invention
The object of the present invention is to provide a kind of composite synergist for cement that can reduce cement production consumption, improve cement quality.
The object of the present invention is achieved like this: it is that sodium pyrosulfate 65-85%, molasses 10-25% and ethylene glycol 5-10% form by weight ratio.
Product of the present invention joined according to 0.05% the ratio that accounts for cement raw material weight carry out grinding in the cement raw material again, can improve grinding effect, reduce the grinding energy consumption, improve mill efficiency.Promptly under the identical condition of cement fineness, can increase output; Consume under the identical condition with mill power at cement output, can increase the specific surface area of cement, thereby improve the quality of cement.Product of the present invention adds in the cement, not only can not bring disadvantageous effect to the performance of cement, can improve the early strength of cement on the contrary, experimental results show that 3 days ultimate compression strength can improve 5-20%, ultimate compression strength can improve more than 10% in 28 days, and weather resistance, frost resistance, impermeability, steaming raising effect and shrinkage performance all are better than the cement additive that sell the domestic market.
(4), specific embodiments
For example the present invention is done more detailed description below:
Be sodium pyrosulfate (NaHSO by weight
4) 65-85%, molasses 10-25% and ethylene glycol (CH
2OH-CH
2OH) ratio of 5-10% becomes product with each mixed raw material.
Be sodium pyrosulfate (NaHSO by weight
4) 70%, molasses 20% and ethylene glycol (CH
2OH-CH
2OH) 10% ratio becomes product with each mixed raw material.
Be sodium pyrosulfate (NaHSO by weight
4) 80%, molasses 15% and ethylene glycol (CH
2OH-CH
2OH) 5% ratio becomes product with each mixed raw material.
Be sodium pyrosulfate (NaHSO by weight
4) 65%, molasses 25% and ethylene glycol (CH
2OH-CH
2OH) 10% ratio becomes product with each mixed raw material.
Claims (1)
1, a kind of composite synergist for cement is characterized in that: it is that sodium pyrosulfate 65-85%, molasses 10-25% and ethylene glycol 5-10% form by weight ratio.
