Description
Technical field
The invention belongs to building material technical field, more particularly, to a kind of ultralow hot eco-cement.
Background technology
Cement is the indispensable important building materials of the development of the national economy.The height being brought in the evolution of cement industry
The problems such as power consumption, high carrying capacity of environment, is increasingly subject to the attention of people.Energy-saving, minimizing waste gas discharge has become as countries in the world
Cement industry realizes the Main way of sustainable development.Realizing one of main path of this breakthrough is that Devoting Major Efforts To Developing is new
Energy-conservation, the low-heat cement of low environmental load.
Low-heat cement is defined as the Portland clinker with proper composition by gb200-2003, adds proper amount of gypsum,
The levigate hydraulic cementing materials with low hydration heat made, referred to as low-heat portland cement (abbreviation low-heat cement), code name
p·lh.The content of dicalcium silicate should be not less than 40%, and the content of tricalcium aluminate should be less than 6%, and the content of free calcium oxide should
Less than 1.0%, sulfur trioxide content is not more than 3.5%.Compared with common portland cement, low-heat cement has low energy and disappears
Consumption, low environmental load, low hydration heat, good high-temperature stability, contract with dry rate be little and additive adaptability is good, later strength increases
Enter rate big the advantages of, meet current international cement industry energy-saving, environmental protection, economize on resources and high-performance and sustainable development will
Ask, be described as " eco-cement ".Low-heat cement has so excellent performance, and the building material industry in China but seldom has at present
Produce with application, its main cause be low-heat cement early strength low relative to common portland cement it is difficult to meet construction
The requirement of speed of application.Therefore, the early strength how improving low-heat portland cement is to the industry metaplasia promoting low-heat cement
Produce and be particularly important with scale application.
Content of the invention
It is an object of the invention to provide a kind of process is simple, low cost, performance are good, meet the ultralow heat of energy-saving and emission-reduction requirement
Eco-cement.
Realize the object of the invention the technical scheme is that
The ultralow hot eco-cement that the present invention provides, is made up of the raw material mixing of following mass percent:
Portland clinker or finished product 10～90%, igneous rock powder 10～90%.
Described Portland clinker or the label >=425# of finished product；By mass percentage, contained free calcium oxide≤
3.0%th, magnesium oxide≤6.0%, sulfur trioxide≤3.5%, specific surface area >=300m2；Tested by gb1346, the presetting period >=
45min, final setting time≤12h.
Described igneous rock powder is basalt powder, pacifies one or more of long rock dust, diabase flour, gabbro powder, described
Basalt powder, pacify long rock dust, diabase flour, several in gabbro powder are mixed using arbitrary proportion.
Described basalt powder, the long rock dust of peace, diabase flour, gabbro powder should meet gb/t203 with regard to high-class product slag
Regulation, by mass percentage, contained sulfur trioxide≤0.3%.
Beneficial effect:
1st, simple production process of the present invention, raw material is easy to get, and only need to be simply mixed raw material and uniformly obtain final product product, need not calcine consuming
Fire coal, does not produce waste gas, waste water, waste residue, is conducive to cement production enterprise to go production capacity, product up-gradation transition in the current generation, real
Existing economy capable of circulation and sustainable development, reach environmental protection, energy-conservation, the purpose increased income, lower consumption.
2nd, compared with existing low-heat cement, the present invention all has larger at aspects such as the heat of hydration, the resistance to compression of early stage, rupture strengths
Advantage.
3rd, there is the endurance quality that like product hardly matches, and possess early strong, superperformance hard soon, perfect correlation
Low-heat cement deficiency in this regard, has taken into account that corrosion resistance, chemical stability be high, wear-resisting, high temperature resistant, freezing tolerance is strong simultaneously
Many advantages, such as (freeze proof grade >=f300 time), the presetting period can shift to an earlier date 1 hour.
4th, can be used as hydraulic engineering cement, cement for construction in sea, dam cement, oil-well cement, low grade fever road cement and be used for substantially
Long-pending concrete works, can be widely applied to the fields such as airport, bridge, harbour, highway, railway and underground urban construction.
Further illustrate technical scheme with reference to embodiment.
