Abstract

The present invention uses flyash as mineral water-reducing agent and solves the problem of reusing flyash. The water-reducing agent consists of flyash and stabilizer and it is used to replace partial cement in cement concrete or cement mortar. It can reduce water consumption of concrete, improve its mixing property, raise its strength and prolong its service life.

Description

Flyash mineral water-reducing agent
The present invention relates to a kind of cement water reducing agent, particularly a kind ofly utilize flyash to make mineral water-reducing agent.
At present, cement for building is very in short supply, and holds at high price, and a large amount of flyash can only be used as common brick, building block or adulterant, has wasted utilization of coal ash value greatly, is badly in need of seeking the stable new way of utilizing.
The purpose of this invention is to provide a kind of pulverized fuel ash as raw materials of using, turn harm into good, turn waste into wealth, the mineral water-reducing agent that water-reducing effect is good.
Technical scheme of the present invention is: the present invention is made up of flyash and stablizer, makes the main raw material of mineral water-reducing agent with flyash, and the selected and processing with flyash: the component of flyash mineral water-reducing agent is by weight:
Flyash 98%--100%
The stablizer 0--2% wherein component of flyash is by weight:
SiO 2, AL 2O 3And Fe 2O 3Mixture 80%--90%
The mixture 2%--10% of CaO and MgO
SO 3 0.1％--3％
K 2O and Na 2The mixture 0.4%--1.5% of O
Loss on ignition 0.5%--6% wherein stablizer is made up of opaque admixture or fluidizer and inorganic siliceous powder, and it is by weight:
Opaque admixture or fluidizer 2%--10%
Inorganic siliceous powder 90%--98%
The present invention is energy part place of cement in cement concrete or sand-cement slurry, reduces the concrete water amount, improves concrete workability, improve concrete strength, prolong concrete work-ing life, saved the energy, reduced investment, cost reduces, environment is optimized, all favourable in state in the people.
Below in conjunction with embodiment the present invention is elaborated,
Embodiment one:
The component of flyash mineral water-reducing agent is by weight:
Flyash 98%
