Mechanical Properties of Post-fire Inorganic Polymer Concrete Columns under Eccentric Compression

The basic mechanical properties (tensile strength, compressive strength, elastic modulus, Poisson’s ratio) of inorganic polymer concrete were studied by test in this paper, which were compared with the performances of common concrete under same strength. According to the stress-strain full curve test results of inorganic polymer concrete under uniaxial compression, adopted the relational expression by the code for design of concrete structure, the equivalent uniaxial compression constitutive relation for inorganic polymer concrete could be got by correcting relevant parameter. The bearing capacity and deformation calculated by theoretical formula were compared with the test results. All of them are in good conformity.

Inorganic polymer material is a new green energy-saving building material which has a broad development prospect. It has been a hot engineering research issue. In this paper, inorganic polymer concrete is made by using fly ash, mineral powder and alkaline activator. Its basic mechanical properties are studied by the cube compressive strength test, the drying-wetting cycle test and flexural strength test and compared with the ordinary concrete in the same sand ratio. The compressive strength of inorganic polymer concrete specimen with mineral powder in early days is much greater than the same level of ordinary concrete. Without mineral powder, its compressive strength has developed rapidly in the early days, but it become very slower in the later days. Furthermore, its ultimate compressive strength is less than the same level of ordinary concrete. After the drying-wetting cycles, the compressive strength of the inorganic polymer concrete specimen is lower than that of the standard conservation. The reduction rate with mineral powder is smaller. The flexural failure characteristics of inorganic polymer concrete specimen are the same with ordinary concrete. However, its bending strength is lower than the same level of ordinary concrete specimen. Research results provide valuable experimental data for the engineering application of inorganic polymer concrete.

Abstract The paper presents an impact of the addition of industrial machining chips on the mechanical properties of polymer concrete. As an additional filler, six types of industrial waste machining chips were used: steel fine chips, steel medium chips, steel thick chips, aluminium fine chips, aluminium medium chips, and titanium fine chips. During the research, the influence of the addition of chips on the basic parameters of mechanical properties, i.e., tensile strength, compressive strength, splitting tensile strength, and Young’s modulus, was analyzed. On the basis of the obtained results, conclusions were drawn that the addition of chips from machining causes a decrease in the value of the mechanical properties parameters of the polymer concrete even by 30%. The mechanism of cracking of samples, which were subjected to durability tests, was also explored. In addition, it was found that some chip waste can be used as a substitute for natural fillers during preparation of a mineral cast composition without losing much of the strength parameters.

Mixture Ratio Design

norganic polymer concrete of a new environment-friendly material has been the hot issue in engineering research so far. For this new material, the main job of the paper includes: we design mixture ratios of inorganic polymer concrete by ourselves, testing the concrete in the age periods of 3, 7, 28 d. The results indicate that this kind of material strength develops mainly in the first 3 d, the strength grows slowly in the later stage; the dry shrinkage of the configured concrete properties are measured, the curve of dry shrinkage shows that the dry shrinkage occurs mainly in the first 14 d and develops slowly in the late; And measure the expansion performance of the concrete member mixed the different categories expansive agent, the results show that the volume growth of mortar specimens to join HCSA expansion agent are obvious; Test results provide a certain basis for the inorganic polymer concrete of micro expansion.
