High-performance concrete construction pretreatment process

Abstract

The invention discloses a high-performance concrete construction pretreatment process. The process comprises a placement plate and a transportation channel, wherein the transportation channel is fixed to the middle of the bottom end of the placement plate; a conveying mechanism is arranged in the middle of the top end of the placement plate; the conveying mechanism comprises a lower conveying box, an upper conveying box, a cushion block, a conveying motor, a rotating shaft and auger blades; and four metering mechanisms are arranged at the top end of the upper conveying box at equal intervals. When a grinding block works, raw materials in a discharging groove can uninterruptedly enter a grinding area through a conveying groove, so that a device does not need to be stopped during adding of the raw materials into the discharging groove in the whole operation process, and the working efficiency can be partially improved; and placement boxes and materials in the placement boxes can apply downward pressure to bearing plates so as to extrude annular pressure sensors, so that the accurate weight of the output materials can be obtained through a weight display screen, and the proportioning is more accurate.

Description

technical field [0001] The invention relates to the field of high-performance concrete, in particular to a pre-treatment process for high-performance concrete construction. Background technique [0002] High-performance concrete takes durability as the main index of design. According to different application requirements, the following performances are guaranteed: durability, workability, applicability, strength, volume stability and economy. For this reason, the configuration of high-performance concrete is characterized by the use of low water-binder ratio, the selection of high-quality raw materials, and the addition of sufficient quantities of admixtures (mineral fine admixtures) and high-efficiency admixtures. [0003] At present, the proportioning of existing high-performance concrete before construction is generally to directly mix the raw materials, so that the raw materials that do not meet the requirements are also directly mixed in. After the concrete is produced,...

Problems solved by technology

[0003] At present, the proportioning of existing high-performance concrete before construction is generally to directly mix the raw materials, so that the raw materials that do not meet the requirements are also directly mixed in. After the concrete is produced, the quality may be unqualified, and some Even using devices such as shovels and buckets for fuzzy proportioning, the quality of the concrete produced in this way will be very different from the required quality, which will seriously affect the quality of the entire project, and even cause danger in the later stage
