Technical field

The invention belongs to concrete renovation agents to repair detection technique field, be related to a kind of concrete renovation agent durability test The testing inspection system of durability in system more particularly to a kind of concrete renovation agent repairing effect.Ts:(concrete renovation agent Durability)

Background technique

The features such as concrete material is because of its compression strength height, good integrity, plasticity height and low cost is usually with reinforcing bar The form of concrete is widely used in major construction project.Construction composed by it is not easy to demolish on a large scale and rebuild, institute It is just extremely necessary with the presence of concrete renovation agent.Current cement concrete patching material can be divided into inorganic and organic by property Two classes, for inorganic material based on cement-based material, hydration rate is fast, at low cost, but failure easy to fall off.Organic material has polymerization Object material, epoxy resin etc., caking property is strong, but easy to aging falls off.It, need to be to the bonding of renovation agent to determine healer properties quality Performance, anti-permeability performance and durability etc. are tested.

Adhesive strength is tested at this stage, is mainly indicated by indirect method with flexural strength, is repaired with half of reparation and centre It repairs to indicate, test flexural strength realizes that three-point bending method has the dimensions requirement to test specimen by three-point bending method, It needs to dispose test arm in corresponding position, test shearing strength is realized by direct shearing test.

In scholar's adhesive strength research at this stage, for testing the test specimen of standard 40mm × 40mm × 160mm used It by using the fritter semi-rigid sub-base material more than relative quantity and is cut into one using intermediate repairing method by production, one equality of horse The size of fixed number amount is 40mm × 40mm × 80mm test specimen, the half block test specimen fragmented into after flexural strength is tested and former cutting 40mm × 40mm out × 80mm test block is fitted into 40mm × 40mm × 160mm mold, prepares cement mortar according to a certain ratio Repair materials are poured into mold and are made having a size of 40mm × 40mm × 160mm cement mortar bonding testing piece；Yang Quanbing etc. is used Half of repairing method connects the concrete test block for being put into half block in punching block and having fractureed in 40mm × 40mm × 160mm three, then at another Half, which is added renovation agent, obtains having a size of 40mm × 40mm × 160mm cement mortar bonding testing piece；The test specimen of remaining scholar makes Applied mold is similar to both of the above.

Cement concrete repairs interface due to internal structure and hydrated product, vulnerable to air, underground water and soil The chemical erosion of middle harmful components, some organic patching materials even can generate unfavorable shadow to it due to the irradiation of ultraviolet light etc. It rings, causes the decline for repairing the performances such as interfacial volume deformation, intensity and service life so that the structure that is repaired more at present is not up to To causing secondary destruction life expectancy.However mold used in test mode at this stage is merely capable of completing intensity survey It has a try the production of part, the durable Journal of Sex Research of renovation agent is not paid attention to, so the mold of existing test Repair strength Lack the design for related durability test.

Influencing concrete structure durability key factor is harmful ion corrosion function, wherein sulfate ion, chloride ion The effects of it is relatively conventional.There are many varieties in saline-alkali areas in the provinces such as China Hebei, Shandong, Qinghai, once occurred concrete sewer pipe, Concrete foundation, concrete culvert etc. destroy situation, concrete structure highway, overpass, the water of the cold districts such as Jinan, Zhengzhou All there are problems that concrete structure in the buildings such as electrical engineering by sulfate attack.China's research sulfate invades concrete Erosion be since in the 1950s just, be substantially carried out the test method and failure mechanism of resisting erosion of sulfate.Sulfuric acid Root penetrates into inside concrete from the external world, and chemical reaction occurs with certain components of concrete and generates erosion to it.

Since the real life intermediate ion corrosion function period is longer, therefore mainly use electric osmose pulse in the lab at this stage Real-life long-time is simulated to use.Electric osmose pulse technique is produced between additional power source anode and cathode using electric osmosis principle Raw potential difference promotes cation to drive hydrone by bonding interface to cathode flow, to reach under positive voltage pulse effect To the effect of accelerated test.Cement concrete sulfate attack in Practical Project is accelerated for electric pulse mode, Wang Chong etc. is at it It is against corrosion under different eating conditions from the concrete of doping quantity of fly ash by testing Different Water-Cement Ratio, immersion way in research Coefficient acts on lower its test result of sulfate attack mechanism using scanning electron microscope analysis electric pulse and shows that electric pulse accelerates The sulfate attack of concrete, the concrete Sulphate-resistant property accelerated test method based on electric pulse principle are technically feasible. Liu Huanqin describes specific research method and device in its research, only forms a concrete sample, both sides in mold For solution, electrode is inserted into solution, connects impulse generator, do comparative analysis using clear water complete immersion and sodium sulphate complete immersion.

But ion erosion is one of the factor for influencing durability, environment temperature, humidity etc. are to renovation agent working condition Influence with performance is that significantly, the reparation interface of different renovation agents and concrete is shown completely not under difficult environmental conditions With anti-cracking ability, intensity and endurance, detecting in previous healer properties room is the wet standard state such as isothermal, Do not consider the coupling of multi-environment factor, therefore leads to desk research and the practical disconnection of application.In order to efficiently use, improve The quality of reparation, the endurance issues for testing renovation agent under the multi-environment factor coupling of lab analysis are imperative.

Have to the simulation of concrete actual working environment and performance test mainly using foundation large-scale environmental simulation test room Method, China Mining University etc. once carried out similar research, but disadvantage is to build and maintenance cost is high, and time-consuming, it is difficult to Receive by general Study and using unit.Large-scale environmental simulation test room is not suitable for small-sized reparation Interface Study, and not Consider the special tectonic of the reparation durable Journal of Sex Research in interface.

Since existing mold can not meet durability test and adhesive strength test simultaneously at this stage, in order to complete Whole efficient detection goes out renovation agent repairing performance, it is necessary to make a kind of examination that durability test (accelerated test) can be carried out to sample Check system reduces the difficulty of healer properties detection and improves the efficiency of detection.

Summary of the invention

In view of this, the present invention simulates above-mentioned existing for mold ask to solve existing concrete renovation agent detection effect Topic, provides a kind of concrete renovation agent endurance test system, which can integrate more Aspect environmental factor, batch complete the durability test of concrete renovation agent, while reducing the difficulty of healer properties detection and mentioning The efficiency of high detection.
