Performance test
1, measurement method
Final products made from embodiment 1-4 are successively poured into 1-4 column element mold respectively, are made after being packed into half amount
Insertion is carried out with vibrating spear to vibrate, is then further continued for loading, and carries out secondary vibration again after filling up, it is extra that end of vibrating scrapes off
Mixture, smooth out surface after component is made, covered after Surface hardened layer with plastic cloth, and daily regular watering is supported
Shield, it is contemplated that epoxy resin cementitious material is slower than hardening of cement speed, therefore demoulding again after a week.
The C100 concrete bought from market is poured into No. 5 column element molds, is carried out after being packed into half amount using vibrating spear
Insertion is vibrated, and is then further continued for loading, and carries out secondary vibration again after filling up, and end of vibrating scrapes off extra mixture, is smeared
Flat surface is covered after Surface hardened layer with plastic cloth, maintenance.
The size of table 1-1 column component
1, test index
Ultimate bearing capacity, ductility.
3, shown in test result is as follows table 1 and Fig. 1:
The characterization result of 1 embodiment 1-4 and C100 concrete column of table
Note: slenderness ratio: refer to the ratio between the length of rod piece and the radius of gyration of bar cross section.μ: the length factor of rod piece, when
When compression bar pin-ended, μ=1；When the fixed other end in compression bar one end is hinged, μ=0.7；When compression bar both ends are fixed, μ=
0.5；When the fixed other end in compression bar one end is free, μ=2.
As can be seen from Table 1, the ultimate bearing capacity of epoxy resin concrete column of the present invention subtracts with the increase of slenderness ratio λ
It is small.When 20 λ≤28 <, the amplitude that ultimate bearing capacity reduces is within 10%, and as λ >=35, the reduction amplitude of ultimate load is super
Cross 20%.And with the increase of slenderness ratio λ, longitudinal limiting strain is smaller and smaller, and lateral displacement is increasing.
Wherein, ring described in Fig. 1 is indulged as embodiment 4；Element is indulged as C100 concrete column.
As seen from Figure 1, in embodiment 4 neo-epoxy resin concrete column and common plain concrete columns carry out pair
Than it can be concluded that, the column of identical size, the two is close in ultimate bearing capacity size, but in terms of ductile performance, in embodiment 4
Neo-epoxy resin concrete to be far superior to common plain concrete.
Also, the destruction of the epoxy resin concrete column in embodiment 4 experienced elastic stage, elastic-plastic phase and destruction
Stage.In the horizontal direction, with the increase of load, eccentric compression phenomenon is more and more obvious, and last component is in pressure and moment of flexure
It is always destroyed jointly with lower.The damage -form of neo-epoxy resin concrete column component had both been different from the strength failure or not of short column
It is same as the unstable failure of long column, but one kind therebetween belongs to eccentric compression destruction.
Also, neo-epoxy resin concrete of the present invention is a kind of efficient, environmentally friendly, energy-efficient construction material, itself has
Intensity is high, and toughness is strong, and corrosion-resistant, crack resistance is good, the strong advantage of fire resistance.Compared with common concrete material, with stronger
Plasticity, be provided simultaneously with many-sided advantages such as component can assemble, construction technology is simple.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.For device disclosed in embodiment
For, since it is corresponded to the methods disclosed in the examples, so being described relatively simple, related place is said referring to method part
It is bright.
