Description
Technical field
The present invention relates to a kind of method that flyash in concrete is directly substituted using cinder of electric power plant, belong to construction material skill
Art field.
Background technology
Concrete is the main material in engineering construction, in building, structures, road, bridge, water conservancy projects, municipal administration
There is utilization in the project constructions such as engineering.Common C30, C40 concrete mainly by cement, flyash, rubble, sand, additive and
Water, which mixes and stirs, to be formed, and because concrete demand is very big, the flyash dosage as one of the main admixture of concrete also sharply increases,
The situation that supply falls short of demand is caused, causes flyash price and Cost of Concrete drastically to raise.
In production, cause the cost of concrete to raise due to the high cost of flyash, often passed through using cinder of electric power plant
Handle and obtain flyash and be used to produce concrete, cinder of electric power plant can not only be carried out to waste utilization, and be advantageous to protect
Retaining ring border.But it is higher to the quality requirement of cinder of electric power plant in existing cinder of electric power plant concrete technology, and processing procedure also needs to
Special machinery is equipped with, complex treatment process, cost are high, limit the recycling to cinder of electric power plant.It is a kind of right to need proposition badly
The less demanding concrete product of lime-ash, meet the requirement of production and engineering construction.
The content of the invention
It is to need to use flyash for existing concrete and cause lime-ash to replace present invention mainly solves two technical problems
Complex disposal process, the deficiencies of cost is high when generation utilizes, propose a kind of directly to utilize flyash in cinder of electric power plant replacement concrete
Method, simplify lime-ash processing procedure, realize that cinder of electric power plant is gathered materials on the spot, recycled.
In order to solve the above technical problems, present invention offer is a kind of directly to substitute flyash in concrete using cinder of electric power plant
Method, it is first determined a common C30 and C40 concrete elementary mix ratio, then using control variate method, controlling remaining
In the case of proportioning, using cinder of electric power plant, by grinding and screening technique, the lime-ash of appropriate granularity is obtained, directly instead of coagulation
Flyash in soil, then concrete is obtained according to a conventional method.The amount that replaces that cinder of electric power plant substitutes flyash is 20%-100%.Instead of
Amount determines according to actual conditions, meets concrete performance index, can be determined by testing detection.
The grinding and screening to cinder of electric power plant, it is that first cinder of electric power plant is ground using common grinding machine, then
Sieved using common screen cloth, the cinder of electric power plant that granularity is 0.1-0.8mm is obtained, for replacing the flyash in concrete.Power plant
The granularity of lime-ash according to be actually needed determine.
The present invention obtains concrete, concrete by using lower, the second-rate cinder of electric power plant of cost instead of flyash
Preparation technology is consistent with existing concrete preparation technology, and cinder of electric power plant need to only use simple levigate and screening, thus may be used
Greatly reduce Cost of Concrete.With lime-ash processing procedure can be simplified, realize that cinder of electric power plant is gathered materials on the spot, recycled etc. and has
Point.
