Description
Technical field
The present invention relates to the field of building materials.It is more particularly related to a kind of high strength concrete admixture and its
Preparation method and application.
Background technique
In high-strength concrete production is prepared, often cement consumption is higher, and the heat of hydration is larger, temperature stress and autogenous shrinkage
Carry out hidden danger to the crack band of high-strength concrete, it is high-strength mixed that result of study both domestic and external shows that mineral admixture can be effectively reduced
The Factor of Brittleness for coagulating soil, improves its crack resistance, replaces cement to be to alleviate this to ask using mineral admixture in high-strength concrete
The effective means of topic.
A kind of waste residue for the phyllosilicate material being discharged from blast furnace when blast-furnace cinder is manUfaCtUre of pig iron.Blast-furnace cinder be by
Gangue, ash content, fluxing agent and other not can enter the impurity in the pig iron composition, be a kind of eutectic mixture.Blast-furnace cinder is
A kind of common concrete mineral admixture, due to its have the advantages that it is low in cost, it is more in the preparation of China's normal concrete
Frequently use.However, replacing ratio of the cement in concrete using blast-furnace cinder merely, effect is barely satisfactory, and by
It has been greatly reduced in the Blast Furnace Ore quantity of slag of the raising of modern ore dressing and ironmaking technology, pig iron output per ton.
Some researches show that the mechanism of action of the different minerals additive in concrete is not quite similar, and mineral additive is mentioning
In terms of high concrete while performance, otherwise performance also will affect.Have both at home and abroad it is relevant research shows that: outside mineral
Add between agent it is mutually compound can produce synergistic effect or super-additive effect, i.e., variety classes mineral additive is compound can play respectively
The advantages of to reach mutual supplement with each other's advantages effect.Therefore, on the basis of common blast-furnace cinder, researching and developing a kind of can promote its agent on crack resistance of concrete
The pressure admixture that performance is more excellent, brittleness is small has a vast market foreground.
Summary of the invention
It is an object of the invention to solve at least the above problems, and provide the advantages of at least will be described later.
A further object of the invention be by introduced under preference temperature waste edible fungi residue and blast-furnace cinder with

The invention also discloses a kind of applications of high strength concrete admixture, in High-strength Concrete Mix, the blending
The mass fraction for expecting to replace in concrete cement is 25%-35%.
In order to illustrate technical effect of the invention, the present inventor prepares respectively for embodiment 3 and embodiment 4
Admixture M1 and M2 carry out preparation high-strength concrete, the mass fraction for studying cement replaced admixture is anti-to high-strength concrete
Compressive Strength and brittle influence are shown in Table 2 and table 3 respectively.
The wherein formula of conventional concrete are as follows: cement 600kg, river sand, rubble and water-reducing agent amount to 1900kg, water 145kg.
The present invention replaces in conventional concrete 25% cement as cement replaced comparative example admixture using conventional existing admixture M0
Mass fraction is shown in Table 1 to High Strength Concrete Under Compressive Cyclic Loading intensity and brittle influence.
Table 1.M0 admixture replaces cement on concrete crushing strength and brittle influence
Table 2.M1 admixture replaces cement quality score on concrete crushing strength and brittle influence
Table 3.M2 admixture replaces cement quality score on concrete crushing strength and brittle influence
In conjunction with Tables 1 and 2 as can be seen that conventional in admixture, with comparative example prepared by the embodiment of the present invention 3 mix
It closes material to compare, when cement replaces mass fraction to be all 25%, compression strength is remarkably reinforced, and brittleness is obviously reduced；From table 2
As can be seen that increasing to 60% with M1 admixture substitution cement quality score, resistance to compression degree is gradually increased, still
Brittleness is also gradually increased, and general compression strength value is enough in 100-120 in high-strength concrete, and Factor of Brittleness also controls at this time
8.0 or so, therefore replace cement quality score to be advisable for 25%-35% with M1 admixture.
When can be seen that with table 3 with M1 admixture and identical M2 admixture substitution cement quality score in conjunction with table 2, M2
Concrete its resistance to compression degree size variation prepared by the concrete of preparation and M1 is unobvious, and the concrete of M2 preparation its brittleness
There is a degree of reduction, can be illustrated with this, the M2 admixture that processing obtains is modified to composite fibre, it can be in certain journey
It spends in the brittleness for reducing concrete.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
In specific details and embodiment shown and described herein.
