Production method of low-viscosity ultrahigh-strength concrete

Abstract

The invention discloses a production method of low-viscosity ultrahigh-strength concrete. The production method comprises the following steps: 1, selecting raw materials for concrete production; wherein the raw materials comprise the following components in parts by weight: 320 to 450 parts of cement, 300 to 420 parts of stone, 600 to 860 parts of sand, 260 to 400 parts of water, 35 to 50 parts ofa water reducing agent, 95 to 105 parts of fly ash, 42 to 57 parts of basalt, 12 to 25 parts of quartz and 15 to 32 parts of mineral powder, and weighing the raw materials in parts by weight. According to the concrete, the mineral powder, the quartz and the basalt are added, so that the ultrahigh strength of the concrete is effectively improved; the viscosity effect between concrete is reduced byadding the water reducing agent, concrete production is stirred, mixed and conveyed by arranging a stirring and conveying device, the stirring and mixing effect between concrete raw materials is effectively improved, and therefore the structural strength and the use performance are effectively improved.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a production method of low-viscosity ultra-high-strength concrete. Background technique [0002] Concrete is one of the most important civil engineering materials of our time. It is an artificial stone made of cementitious material, granular aggregate water, and admixtures and admixtures added when necessary in a certain proportion, uniformly stirred, compacted, cured and hardened. The price is low and the production process is simple, so it is used more and more. 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 important material. However, the existing concrete structural strength and performa...
