Abstract
The invention relates to environment-friendly slow setting cement for highways, which mainly comprises the following raw materials in portion by weight: 55 to 65 portions of clinker aggregate, 25 to 35 portions of coal ash, 3 to 8 portions of stone, 3 to 8 portions of gypsum, and 1 to 10 portions of retarder TDA. The clinker aggregate mainly comprises the following raw materials in portion by weight: 65 to 66 portions of calcium oxide, 21 to 23 portions of silicon oxide, 5 to 6 portions of aluminum oxide, and 4 to 5 portions of ferric oxide. The cement uses little clay and some correcting raw materials. The cement has the advantages of high strength, good oxidation resistance and alkali resistance, and good grain evenness degree; and all blending processes are finished in a closed environment, and accord with the environment-friendly requirement. The cement is particular applied to paving highway pavement.
Description
Technical field
The present invention relates to a kind of environment-friendly slow setting cement for highways.Belong to the cement technology field.
Background technology
Traditional method for production of cement is with Wingdale, clay, iron, the siliceous correction material abrasive dust of preparing burden by a certain percentage, after the calcining, adds blended material again or directly utilizes calcining back grog to add retardant and carry out grinding and make.Make in this way, mix and a large amount of clays and some correction materials, not only take the farmland, also a large amount of human and material resources of need are developed and taken, and are very inconvenient, not environmental protection.And these strengths of cement are low, anti-oxidant, the alkali resistant voltinism can be relatively poor, and the uniform particles degree is bad.Paving of general road can only be applicable to, and paving of express highway pavement can not be suitable for.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of intensity height, anti-oxidant, alkali resistant voltinism can be better, the environment-friendly slow setting cement for highways of good, the environmental protection of uniform particles degree.
The object of the present invention is achieved like this: a kind of environment-friendly slow setting cement for highways, and described cement mainly is made up of the raw material of following weight part:
Grog 55-65
Flyash 25-35
Stone 3-8
Gypsum 3-8
Retardant TDA 1-10
Described grog mainly is made up of the raw material of following weight part:
Calcium oxide 65-66
Silicon-dioxide 21-23
Aluminium sesquioxide 5-6
Ferric oxide 4-5.
Cement of the present invention mix and clay and some correction materials few.And strength of cement height, anti-oxidant, alkali resistant voltinism can be better, and the uniform particles degree is good, and all blending processes are all finished compliance with environmental protection requirements under the environment of sealing.Be specially adapted to paving of express highway pavement.
Embodiment
One, the preparation of grog
Get calcium oxide 65kg, silicon-dioxide 22kg, aluminium sesquioxide 5kg and ferric oxide 5kg and be mixed with grog.
Two, the mixed preparation of water
Get grog 58kg, flyash 31kg, stone 5kg, gypsum 6kg and retardant TDA 5kg, the adding ball mill carries out grinding, drying is made.
Claims (1)
1, a kind of environment-friendly slow setting cement for highways is characterized in that: described cement mainly is made up of the raw material of following weight part:
Grog 55-65
Flyash 25-35
Stone 3-8
Gypsum 3-8
Retardant TDA 1-10;
Described grog mainly is made up of the raw material of following weight part:
Calcium oxide 65-66
Silicon-dioxide 21-23
Aluminium sesquioxide 5-6
Ferric oxide 4-5.
