Abstract
The invention discloses a composite cementitious material and a preparation method thereof; the composite cementitious material comprises portland cement, fly ash, steel slag powder, granulated blast furnace slag, a volcanic ash mixed material, silicon ash, a sulfate activator, an alkali activator, an additive, and the like, and is prepared by processes such as mixed-grinding, stirring, etc. The advantage is that the composite cementitious material has high early strength, frost resistance, seepage resistance, and no pollution, can improve the stability of concrete, has low cost, and simple process, and can be used as a cementitious binder of high-performance concrete.
Description
Technical field
The present invention relates to a kind of composite gelled material and preparation method thereof.
Background technology
Generally adopt original state flyash or ground slag blended material and concrete adulterant in China as cement, but flyash and slag are during as starting material production gelling material, parameter is low, activity is not high, poor stability, influence the quality of construction work, though exciting with the method for Study of Activation of present flyash is more, excite method greatly as mechanical grinding method, lime three, these method production costs are higher, investment is big, complex process but adopt, and are not suitable for large-scale application.
Summary of the invention
A technical problem to be solved by this invention is: provide a kind of morning strong height, the composite gelled material that freeze proof anti-permeability performance is good.
For solving the problems of the technologies described above, the technical scheme that adopts is:, a kind of composite gelled material, comprise silicate cement and flyash, the weight ratio of each component is: silicate cement 20-70%, flyash 30-55%, active material 0-65%, sulphate activation agent 1-8%, alkali-activator 0.5-15%, compound additive 0.05-3.5%, water reducer 0-1%, air entrapment agent 0-0.025%; Described active material comprises steel-making slag powder, calcareous addition of volcano etc.; Described compound additive comprises hardening accelerator, grinding aid etc.
The preparation method of composite gelled material: flyash, sulphate activation agent, alkali-activator etc. are added grinding machine successively, mix grinding 30-70 minute, add compound additive, water reducer, air entrapment agent etc. again, be milled to required fineness and obtain abrasive material, then abrasive material and silicate cement are added mixing machine, stir, promptly get composite gelled material.
Beneficial effect of the present invention: adopted more flyash, slag, utilization of waste material economizes on resources; the protection environment; simultaneously composite gelled material has early strong height, freeze proof anti-permeability performance is good, and highly dense solidity, high-durability and high uniformity can effectively improve the stability of material of construction.
Embodiment
Formula rate: silicate cement 30%, flyash 50%, steel-making slag powder 5%, sulphate activation agent 1-8%, alkali-activator 0.5%, hardening accelerator 0.1%, water reducer 1%, air entrapment agent 0.025%.
Preparation method: flyash, steel-making slag powder, sulphate activation agent, alkali-activator etc. are added grinding machine successively, mix grinding 30-70 minute, add hardening accelerator, water reducer, air entrapment agent etc. again, be milled to required fineness and obtain abrasive material, then abrasive material and silicate cement are added mixing machine, stir, promptly get composite gelled material.
