Manufacturing method of high-performance concrete

Abstract

The invention discloses a manufacturing method of high-performance concrete, relates to concrete, and mainly solves the technical problem of poor mechanical properties in the existing manufacturing method. The method comprises the following steps: S1, carrying out screening treatment, shaping treatment and water washing treatment on coarse aggregate, medium aggregate and fine aggregate; S2, selecting a high-performance polycarboxylic acid additive; S3, respectively weighing the cement, the active admixture, the fine aggregate, the water, the high-performance polycarboxylic acid admixture, themedium aggregate and the coarse aggregate according to the formula ratio; S4, sequentially adding the coarse aggregate, the medium aggregate, the fine aggregate, the cement, the active admixture, thewater and the high-performance polycarboxylic acid admixture into a forced stirrer, and uniformly stirring the mixture to obtain a concrete mixture; S5, separating the concrete mixture into two layersand loading the concrete mixture into a standard test mold, tamping the mixture by a tamping rodin an inserted manner, and demolding the cement mixture after standing treatment for 24 hours, thus preparing a concrete standard test piece; S6, transferring the concrete standard test piece into a standard curing chamber to be cured to the standard age. The mechanical property of the concrete can beimproved.

Description

technical field [0001] The present invention relates to concrete, more particularly, it relates to a kind of high-performance concrete production method. Background technique [0002] Concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water and aggregate in an appropriate proportion, uniformly stirred, compacted and cured. It is the most commonly used material in the construction industry. Definition of high-performance concrete: The industry agrees that it is produced with conventional raw materials and ordinary processes, and has high performance, high durability, and various mechanical properties required by concrete structures. [0003] In the process of concrete production, the mechanical properties and working performance of concrete will be affected due to excessive aggregate impurities, poor aggregate shape quality, poor performance of concrete admixtures, unreasonable consistency of concrete mixture during mixing, or...
