Abstract
The invention discloses a kind of methods for producing high-strength slow setting cement using industrial white sugar, it is characterised in that：The cement is made of following raw material precentagewise composition：Clinker 60%, desulfurated plaster 4%, coal ash 36%；By the industrial syrup of 0.14% addition of cement quality in prepared cement.A kind of method for producing high-strength slow setting cement using industrial white sugar of the present invention not only makes the presetting period of slow setting cement increase by 100 minutes or so using industrial white sugar, and 3 days flexural strengths are greater than or equal to 3Mpa, and compression strength is greater than or equal to 17Mpa within 3 days；Flexural strength is greater than or equal to 6.5Mpa within 28 days；Compression strength is greater than or equal to 40Mpa within 28 days；Sulfur trioxide content is not more than 3.5%, and performance, better than other equality strength rating cements, product workability, guarantor's plasticity, caking property are good, and the concrete uniformity of configuration is good；The present invention can make slow setting cement reduce pollution, environmental protection.
Description
Technical field
The invention belongs to cement technology field, more particularly to a kind of side that high-strength slow setting cement is produced using industrial white sugar
Method.
Background technology
With the fast development of modern architecture, urban construction makes remarkable achievements, and is by engineering properties cement
The most common material of construction industry.At present cement setting time control is required in standard GB/T 175-2007 common portland cements
System, portland cement presetting period are not less than 45min, and final setting time is not more than 390min, Portland cement, slag silicate
Salt cement, Portland pozzolana cement, Portland fly ash cement and composite Portland cement presetting period are not less than
45min, final set are not more than 600min.However have customer according to construction demand, it proposes to increase setting time to meet remote conveying
Cement mortar is sent to carry out engineering construction, we are by increasing mixing material addition content and gypsum addition content, setting time meeting at present
It is corresponding to increase, but cement performance can be influenced, it is difficult to realize the requirement of customer.Therefore, it is particularly important to the solution of the above problem.
Invention content
The defects of it is an object of the invention to overcome the above-mentioned prior art, provides a kind of high-strength slow using industrial white sugar production
The method of condensate mud can solve the problems, such as that slow setting cement initial set and final setting time are short.
In order to achieve the above object, the technical solution adopted in the present invention is as follows：
A kind of method for producing high-strength slow setting cement using industrial white sugar, it is characterised in that：The cement is made of following raw material
Precentagewise forms：Clinker 60%, desulfurated plaster 4%, coal ash 36%；By 0.14% addition of cement quality in prepared cement
Industrial syrup.
Further, the industrial syrup is by sugar and water 1:3 dilution proportion.
Further, in the slow setting cement sulfur trioxide content 2.2 ± 0.2%.
Further, the grinding fineness of the slow setting cement tails over 4 ± 3% for 45 μm.
Further, the mixing material addition content of the slow setting cement is 36 ± 2%.
Advantages of the present invention：A kind of method for producing high-strength slow setting cement using industrial white sugar of the present invention, it is white using industry
Sugar not only makes the presetting period of slow setting cement increase by 100 minutes or so, and flexural strength is greater than or equal to 3Mpa, 3 days pressure resistances within 3 days
Degree is greater than or equal to 17Mpa；Flexural strength is greater than or equal to 6.5Mpa within 28 days；Compression strength is greater than or equal to 40Mpa within 28 days；Three
Sulfur oxide content is not more than 3.5%, and performance, better than other equality strength rating cements, product workability protects plasticity, bonding
Property is good, and the concrete uniformity of configuration is good；The present invention can make slow setting cement reduce pollution, environmental protection.
Specific embodiment
The invention will be further described, but is not to be construed as to the scope of the present invention for example given below plan
Limitation, those skilled in the art still fall within this according to some the nonessential modifications and adaptations of the content of present invention to the present invention
The protection domain of invention.
Embodiment
When producing P.F32.5 cement, industrial white sugar is pressed 1:3 dilution proportion is added to by the 0.14% of cement quality
In P.F32.5 cement.
By aforementioned production method and norm controlling, the P.F32.5 cement indices that final production goes out are as follows：
It can be seen that indices are satisfied by standard gauge provisioning request, and setting time more normally produces cement and increases a 100min left sides
The right side can meet client's construction requirement.
The dilution of industrial white sugar and addition content are crucial, need accurately to be calculated according to yield before manufacture, while
Ensure the incorporation of continuous-stable in production process.
