Problems solved by technology

[0006] However, there are still many deficiencies in the existing technology. For example, it is usually necessary to manually weigh and configure the materials, and it is impossible to realize automatic weighing and unloading after weighing; the internal materials of the lifting conveying pipeline often agglomerate reunion phenomenon

Abstract

The invention discloses impermeable wear-resistant concrete and a preparation method thereof, and relates to the technical field of concrete preparation. The impermeable wear-resistant concrete comprises the following raw materials: cement, fly ash, blast furnace slag, quartz sand, broken stone, carbon black, a fiber filler, sodium alkyl benzene sulfonate, a water reducer, polyvinyl alcohol, an impermeable wear-resistant composition and water. The preparation device comprises a batching mechanism, a lifting and conveying mechanism and a mixing and stirring mechanism, wherein the discharging port end of the batching mechanism is connected with the feeding end of the lifting and conveying mechanism; and the discharging end of the lifting and conveying mechanism is connected with the discharging end of the mixing and stirring mechanism. According to the impermeable wear-resistant concrete and the preparation method thereof provided by the invention, prepared materials can be transferred at the same time, so that automatic unloading after weighing is realized; the inner wall of a lifting pipeline can be effectively prevented from being blocked while the materials are lifted and conveyed upwards; and the preparation method is simple, and the prepared concrete has the characteristics that the water-reducing rate is high, the workability and the fluidity of the road concrete are obviously improved, and the impermeability, the freezing resistance, the fracture resistance, the compression resistance, the wear resistance and the durability of the road concrete are improved.

Description

technical field [0001] The invention relates to the technical field of concrete preparation, in particular to an anti-seepage and wear-resistant concrete and a preparation method thereof. Background technique [0002] Concrete is one of the most important civil engineering materials today. It is a kind of artificial stone made of cementitious materials, granular aggregates, water, and admixtures and admixtures added when necessary, prepared in a certain proportion, uniformly stirred, compacted, cured and hardened. Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an...
