Abstract
The present invention provides a kind of rapid detection method of brick content in regenerated coarse aggregate, this method calculates the brick content in regenerated coarse aggregate by measuring regenerated coarse aggregate water absorption rate.Functional relation between brick content in the regenerated coarse aggregate and regenerated coarse aggregate water absorption rate is：X=7.6098y 23.5385；Wherein：X indicates the brick content in regenerated coarse aggregate；Y indicates regenerated coarse aggregate water absorption rate.The ongoing change that the present invention passes through test regenerated coarse aggregate water absorption rate, it is known that the content of brick in regenerated coarse aggregate, innovation have developed brick content rapid detecting technology in construction refuse regenerated coarse aggregate.
Description
Technical field
Building engineering field of the present invention, is related to regenerated coarse aggregate, and in particular to brick content in a kind of regenerated coarse aggregate
Rapid detection method.
Background technology
Due to the particularity of regenerated coarse aggregate production technology, the brick of regenerated coarse aggregate after the techniques such as broken, screening, dedusting
Block content can not often determine.And part of the brick as most fragile in regenerated coarse aggregate, content is to using regenerated coarse aggregate
Concrete strength influence it is most important.To solve concrete block in the concrete component raw material requirement using regenerated coarse aggregate
The control problem of content needs to find a kind of method of brick content in quick estimation regenerated coarse aggregate, to aggregate performance
Make evaluation.
Invention content
For the deficiencies in the prior art, the object of the present invention is to provide bricks in a kind of regenerated coarse aggregate to contain
The rapid detection method of amount solves the technical issues of prior art can not accurately detect brick content from regenerated coarse aggregate.
In order to solve the above-mentioned technical problem, the application, which adopts the following technical scheme that, is achieved：
The rapid detection method of brick content in a kind of regenerated coarse aggregate, this method, which passes through, measures regenerated coarse aggregate water absorption rate
To calculate the brick content in regenerated coarse aggregate.
The present invention also has following distinguishing feature：
Functional relation between brick content in the regenerated coarse aggregate and regenerated coarse aggregate water absorption rate is：X=
7.6098y-23.5385；
Wherein：X indicates the brick content in regenerated coarse aggregate；Y indicates regenerated coarse aggregate water absorption rate.
Compared with prior art, the present invention beneficial has the technical effect that：
The ongoing change that the present invention passes through test regenerated coarse aggregate water absorption rate, it is known that the content of brick in regenerated coarse aggregate,
Innovation has developed brick content rapid detecting technology in construction refuse regenerated coarse aggregate.
Description of the drawings
Fig. 1 is the water absorption rate relationship of the rate containing brick and recycled aggregate of regenerated coarse aggregate.
Explanation is further explained in detail to the particular content of the present invention below in conjunction with drawings and examples.
Specific implementation mode
Specific embodiments of the present invention are given below, it should be noted that the invention is not limited in implement in detail below
Example, all equivalent transformations made on the basis of the technical solutions of the present application each fall within protection scope of the present invention.
Embodiment 1：
The present embodiment provides a kind of rapid detection method of brick content in regenerated coarse aggregate, and this method, which passes through, measures regeneration
Coarse aggregate water absorption rate calculates the brick content in regenerated coarse aggregate.Brick content and regeneration in the regenerated coarse aggregate is thick
Functional relation between aggregate water absorption rate is：X=7.6098y-23.5385；Wherein：X indicates that the brick in regenerated coarse aggregate contains
Amount；Y indicates regenerated coarse aggregate water absorption rate.
The specific acquisition process of the rapid detection method of brick content is in regenerated coarse aggregate in the present embodiment：Brick
Water absorption rate is much bigger relative to the other components in regenerated coarse aggregate, and the brick content in regenerated coarse aggregate should be with its water absorption rate
There are certain relationships, as long as finding the proportionate relationship, so that it may to estimate wherein brick by measuring regenerated coarse aggregate water absorption rate
Content.For this purpose, devising the totally 11 groups of experiments from 0% to 100% of brick content, the progress of its water absorption rate is measured, test result is shown in Table
1。
The measurement of the different water absorption rates of amount containing brick of table 1
As can be seen from Table 1, aggregate immersion 30min water absorption rates may be considered equal with 60min water absorption rates, therefore will
The water absorption rate of 30min and 60min is averaged, and it is as shown in Figure 1 to draw curve.
As shown in Figure 1, the water absorption rate of regenerated coarse aggregate and amount containing brick are proportional, if water absorption rate is y (%), amount containing brick
For x (%), it is as follows to fit the functional relation between y and x using SPSS softwares：
Y=0.13141x+3.0932 is 1.
X=7.6098y-23.5385 is 2.
Utilize 2. formula, you can its amount containing brick is estimated by the water absorption rate of regenerated coarse aggregate.
By the ongoing change for testing regenerated coarse aggregate water absorption rate, it is known that the content of brick, innovation are ground in regenerated coarse aggregate
Brick content rapid detecting technology in construction refuse regenerated coarse aggregate is sent out.
Claims (2)
1. the rapid detection method of brick content in a kind of regenerated coarse aggregate, which is characterized in that this method is thick by measuring regeneration
Aggregate water absorption rate calculates the brick content in regenerated coarse aggregate.
2. the rapid detection method of brick content in regenerated coarse aggregate as described in claim 1, which is characterized in that it is described again
The functional relation between brick content and regenerated coarse aggregate water absorption rate in raw coarse aggregate is：X=7.6098y-23.5385；
Wherein：X indicates the brick content in regenerated coarse aggregate；Y indicates regenerated coarse aggregate water absorption rate.
