Description
Technical Field
The invention belongs to the technical field of concrete preparation, and particularly relates to a high-performance concrete of a marine engineering material based on vitrified aggregates, and a preparation method and application thereof.
Background
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art that is already known to a person of ordinary skill in the art.
In coastal areas of China, a large number of reinforced concrete structures of marine engineering work directly in marine environments, and concrete bears load and chloride ion corrosion for a long time, the durability problem is increasingly prominent, and particularly, the problem of reinforcement corrosion caused by chloride ions is one of important factors influencing the durability of concrete. However, with the continuous progress of concrete material science, people begin to research the concrete with high workability, high durability and good volume stability, namely high-performance concrete, and the high reinforcement is the direction of the concrete development for hundreds of years, especially in the marine environment and the pouring of high-temperature and high-humidity conditions and bridge piers and wharfs of the sea-crossing bridge.
As a concrete capable of meeting special performance and special purpose, the high-performance concrete marine material can not meet the performance requirement only by adopting the measures of conventional materials, common mixing, pouring, maintenance and the like, but can improve the long-term mechanical property, the initial strength, the rigidity and the volume stability of the concrete and prolong the service life of the concrete in a severe environment by improving the pouring and tamping methods, and the high-performance concrete not only needs high strength, but also has other important properties such as high durability, chemical corrosion resistance and the like, such as high volume stability, high elastic modulus, low dry shrinkage, low creep, low temperature strain, high impermeability and high working performance. Among them, the concrete with good dimensional stability is mainly characterized by high elastic modulus, low drying shrinkage, creep and small temperature strain rate. The concrete with good dimensional stability can reduce the loss of prestress and reduce the primary cracks of the concrete. In order to obtain good dimensional stability, it is necessary to limit the amount of cement used and to use a high-modulus, high-strength coarse aggregate. The high-performance marine concrete belongs to a cement-based porous building material, and in the composition, coarse aggregate and fine aggregate account for about 70% of the concrete, and are the main components of the concrete. But the corresponding manufacturing cost is obviously improved, so the cost of the high-performance concrete is further reduced while the high performance of the concrete is maintained.

Performance testing
1. Test method
The concrete prepared in the examples and the comparative examples is put into a mold; the mould filled with the recycled concrete is vibrated in an insertion mode, and the mould is quickly inserted, slowly pulled and slowly moved clockwise or anticlockwise to achieve uniform compaction; after vibration molding, standing the test piece in an indoor environment for natural maintenance, watering the periphery of the mold, and covering the surface of the mold with a waterproof plastic film; standing for 24 hours, removing the mold, continuously standing the test piece in an indoor environment for natural maintenance, watering the test piece no less than twice a day during the maintenance period, and keeping the surface of the test piece moist; after 7 days of curing, the test piece was taken out and left to stand for 1 day.
(1) And (3) testing the compressive strength: CO88PN100/AZ/0001 model press, G/B loading rate 0.5MPa/s.
(2) And (3) testing the breaking strength: the G/B loading rate of the electro-hydraulic servo fatigue testing machine is 0.5MPa/s.
(3) Durability soak test: a large-scale marine soaking durability test system is simulated, and the accelerated corrosion temperature is 40 ℃.
2. Test results
TABLE 1 concrete test piece Performance test results of examples and comparative examples (7 d)
As can be seen from the results in table 1, the compressive strength and flexural strength of the vitrified aggregate concrete prepared in examples 1 to 4 are improved to a certain extent and also improved to a certain extent in durability compared to the concrete without silica fume, manganese slag and slag in comparative example 3, the concrete with slag only in comparative example 1, manganese slag only in comparative example 2, and silica fume only in comparative example 4 may cause too low early strength and ultimate tensile value of the concrete, so that the concrete cannot withstand early temperature stress and dry shrinkage stress to cause structural cracking and loss of concrete strength, the mechanical properties of the concrete are improved to a certain extent by adding silica fume only, and the mechanical properties of the concrete are not improved to the best effect, possibly due to the alkali-aggregate reaction between silica in silica fume and alkaline substances in cement, although the mechanical properties of the concrete are not improved, the slag or silica fume or manganese slag alone are not improved greatly, while the concrete with no mineral admixture in comparative example 3 is added, and the mechanical properties of the concrete are improved to a certain extent, but the best effect is not achieved. The compressive strength of the large-doping-amount manganese slag, the slag and the silica fume which are mixed in different proportions is higher than the strength and the durability of concrete without doping. The composite mineral admixture forms good micro-gradation in the concrete, and the morphological effect, the interface effect, the micro-aggregate effect, the volcanic ash effect and the like are interactively superposed, so that the corrosion resistance and the durability of the concrete are obviously improved. Based on the interactive additive effect of the composite mineral admixture, through the matching of the mineral admixture, the parameters such as the mixing amount proportion of the mineral admixture and the like are reasonably controlled, and the composite effect of the composite mineral admixture is exerted to the maximum extent so as to meet the technical requirements of maritime work high-performance concrete and form the obvious gain effect on the corrosion resistance and the durability of the concrete, such as the chlorine ion corrosion resistance and the like. Aiming at the gain effect of the composite mineral admixture with large mixing amount on the marine high-performance concrete, the ceramic aggregate concrete has certain enhancement effect on the compressive strength and the flexural strength of the ceramic aggregate concrete, and has better durability.
Finally, it should be noted that, although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention. Although the present invention has been described with reference to the specific embodiments, it should be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
