Description
Technical field
The present invention relates to construction material, field of civil engineering, and in particular to one kind improves rubber in Rubber Concrete
The method that particle floats.
Background technology
Rubber Concrete is to carry out rubber grain by normal concrete to substitute gathering materials for certain volume content resulting
A kind of compound phase material, its not only important in inhibiting in terms of the recycling of rubber, and rubber aggregate coagulation
Soil combines the characteristics of two kinds of materials of rubber and concrete, has in terms of material mechanical performance and endurance quality compared with normal concrete
Great changes, there is more wide application prospect.But on the other hand, since rubber grain belongs to aglite, in rubber
Rubber grain easily floats in the mix and work progress of glue aggregate concrete, has seriously affected in Rubber Concrete
Portion's homogenieity, local defect is produced after easily making concrete hardening, is left hidden danger for concrete structure durability, is shortened concrete
The service life of structure, directly hinders the popularization and application of Rubber Concrete.
The reason for generation rubber grain floats in Rubber Concrete is caused to have a variety of, numerous researchs show rubber aggregate
Water-cement ratio (ratio of water and cementitious material) is to influence the principal element that rubber grain is distributed in concrete in concrete, and with
The increase of water-cement ratio, rubber grain rising phenomenon is further obvious.
The content of the invention
The purpose of the invention is to overcome deficiency of the prior art, there is provided one kind improves rubber in Rubber Concrete
The method that glue particle floats.Using a kind of good high molecular material of water absorbing properties, change cement-based material mix and construction
Shi Youxiao water-cement ratios (disregard high molecular material and absorb part water), so as to achieve the purpose that to control rubber grain to float.
The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of method that rubber grain floats in improvement Rubber Concrete, by being filled in Rubber Concrete
Pulvis shape super absorbent resin, using water suction of the super absorbent resin in Rubber Concrete and releases water behavior, reduces rubber
Effective water-cement ratio when glue aggregate concrete mix and construction, with the situation for controlling rubber grain to float in concrete, specifically
Comprise the following steps：
(1) super absorbent resin quality is weighed, its quality is 5 ‰ of cementitious material quality in rubber concrete；
(2) it is the super absorbent resin of pulvis shape and cementitious material dry mixing is uniform；
(3) Rubber Concrete each component material is put into blender and stirred uniformly；
(4) moulding is carried out after the completion of material mix, maintenance obtains test specimen；
(5) test specimen is cut from centre position vertical forming upper surface after conserving 48h, observes rubber grain distribution in section
Situation.
Compared with prior art, beneficial effect caused by technical scheme is：
The method of the present invention is to reduce rubber collection with releasing water behavior using water suction of the super absorbent resin in cement-based material
Expect concrete mixing when and construction when effective water-cement ratio, so as to improve rising phenomenon of the rubber grain in concrete, with rubber
The progress of hydrated cementitious, is maintained at the water inside super absorbent resin and gradually discharges inside glue aggregate concrete, whole mistake
Total water-cement ratio of Rubber Concrete does not change in journey, does not change Rubber Concrete match ratio and method letter
It is single.
Brief description of the drawings
Fig. 1 is that the test specimen cross-sectional scans figure that the method for the present invention obtains is not used.
Fig. 2 is the test specimen cross-sectional scans figure obtained using the method for the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
This method can improve the situation that rubber grain floats in concrete, and preferred forms are as follows:
(1) experiment is divided into two groups, this group and control group, are denoted as A groups and B groups respectively, its match ratio data is as shown in table 1,
Each component precisely weighs；
Table 1 tests match ratio
(2) it is pulvis super absorbent resin and cementitious material dry mixing is uniform；
(3) Rubber Concrete each component material is put into blender and stirred uniformly；
(4) moulding is carried out after the completion of material mix, sample dimensions are 40mm × 40mm × 160mm；
(5) test specimen is cut from centre position vertical forming upper surface after conserving 48h, observes rubber grain distribution in section
Situation.
As depicted in figs. 1 and 2, be respectively not used and two groups of test specimen sections of A, B for being obtained using the method for the present invention as a result,
Wherein black portions are rubber grain.Significantly change it can be seen that rubber grain its floating situation after this method is handled has
It is kind.
The present invention is not limited to embodiments described above.The description to embodiment is intended to describe and says above
Bright technical scheme, above-mentioned embodiment is only schematical, is not restricted.This is not being departed from
In the case of invention objective and scope of the claimed protection, those of ordinary skill in the art may be used also under the enlightenment of the present invention
The specific conversion of many forms is made, these are belonged within protection scope of the present invention.
Claims (1)
1. a kind of improve the method that rubber grain floats in Rubber Concrete, it is characterised in that by being mixed in rubber aggregate
