Description
Technical field
The present invention relates to construction material, especially, relate to the high intensity cement for construction in sea brick of a kind of applicable ocean engineering.
Background technology
The extra large work cement used in ocean engineering construction now due to sea water do not stop wash away, and rich in there being chloride ion
And the sea water of sulfate is easy to corrode the ocean engineering using sea work cement to build.According to cement for construction in sea technical specification
Particularity, essentially consists in chloride diffusion coefficient and the requirement of resisting erosion of sulfate coefficient, especially because being applied to ocean work
Journey, meeting corrosion resistance of chloride ion becomes the key of technology.Existing sea work cement not only intensity is low, and corrosion resistance of chloride ion
Ability and resisting erosion of sulfate ability also ratio are relatively low, are badly in need of a kind of intensity of invention high, corrosion resistant sea work cement brick.
Summary of the invention
Present invention aim at providing a kind of high intensity cement for construction in sea brick, to solve in prior art cement for construction in sea brick not only
Intensity is low, and the most corrosion resistant technical problem.
For achieving the above object, the present invention provides a kind of high intensity cement for construction in sea brick, by the raw material group of following parts by weight
Become: natural gypsum 5-8 part, stone nitre 30-40 part, breeze 25-30 part, flyash 8-12 part, silicon ash 5-8 part, grog 33-55 part,
Cement 20-25 part, rock sand essence 8-10 part.
Further, it is made up of the raw material of following weight portion: the described natural gypsum 6 parts, 35 parts of described stone nitre, described breeze
28 parts, 10 parts of described flyash, described silicon ash 7 parts, 50 parts of described grog, described cement 23 parts, described rock sand essence 9 parts.
Further, described cement fineness modulus is 3-2.3.
The method have the advantages that and the invention provides a kind of high intensity cement for construction in sea brick, have high-durability,
High application property, high intensity, can be mainly used in the solidifying mixed geotechnique of the arrangements of reinforcement such as ocean armored concrete engineering, deicer salts road, bridge
Journey.
Detailed description of the invention
A kind of high intensity cement for construction in sea brick that this preferred embodiment provides, it is as follows that it implements process:
The present invention provides a kind of high intensity cement for construction in sea brick, is made up of the raw material of following parts by weight: natural gypsum 5-8 part, stone
Nitre 30-40 part, breeze 25-30 part, flyash 8-12 part, silicon ash 5-8 part, grog 33-55 part, cement 20-25 part, rock sand essence 8-
10 parts.
Preferably, it is made up of the raw material of following weight portion: the described natural gypsum 6 parts, 35 parts of described stone nitre, described breeze 28
Part, 10 parts of described flyash, described silicon ash 7 parts, 50 parts of described grog, described cement 23 parts, described rock sand essence 9 parts.
Preferably, described cement fineness modulus is 3-2.3.
Embodiment 1
The natural gypsum 5 parts, 40 parts of stone nitre, breeze 30 parts, 8 parts of flyash, silicon ash 8 parts, 33 parts of grog, cement 25 parts, rock sand essence
10 parts, add suitable quantity of water compacting after the raw material pulverizing of above-mentioned parts by weight and form.
Embodiment 2
The natural gypsum 6 parts, 35 parts of stone nitre, breeze 28 parts, 10 parts of flyash, silicon ash 7 parts, 50 parts of grog, cement 23 parts, rock sand essence
9 parts, add suitable quantity of water compacting after the raw material pulverizing of above-mentioned parts by weight and form.
Embodiment 3
The natural gypsum 8 parts, 30 parts of stone nitre, breeze 25 parts, 8 parts of flyash, silicon ash 5 parts, 55 parts of grog, cement 20 parts, rock sand essence 8
Part, add suitable quantity of water compacting after the raw material pulverizing of above-mentioned parts by weight and form.
The production raw material of high intensity cement for construction in sea brick is with stone nitre, grog, breeze, cement etc. as primary raw material, cement
Grinding be key one step of cement brick, use open circuit Super-fine grinder grinding system clinker grinding and mixing material to mix by after homogenizer
Enter slag powders and prepare cement brick.Due to cement fineness increase, cement chloride diffusion coefficient substantially reduces, cement anti-chlorine from
Sub-erosiveness and early strength are remarkably reinforced.The Ca(OH produced with hydrated cementitious due to breeze)2Turned by pozzolanic reaction
Become stable low alkalinity C-S-H gel, be effectively filled with macroporous structure, refined pore structure；C due to breeze3A content
Height, sulfate radical content is low, and hydrated product alkalescence is low, thus its chloride binding capacity is higher, and incorporation breeze is conducive to cement
Later strength development preferably, there is high intensity, ocean armored concrete engineering, deicer salts road, bridge can be mainly used in
Deng the solidifying mixed geotechnique's journey of arrangement of reinforcement.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention；Skill for this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
