High-performance concrete preparation method

Abstract

The invention discloses a method for preparing high-performance concrete, which comprises the steps of determining concrete design parameters according to the performance requirements of the concrete,and obtaining the detection data of the raw materials by detecting the raw materials for preparing the concrete; determining the water consumption of the concrete mixture, the utilization amount of acementing material, and the utilization amounts of cement, slag powder and fly ash according to the concrete design parameters and converting the apparent density of the cement, the slag powder and the fly ash into the mass amount according to the raw material detection data; determining the sand rate according to the particle size of coarse aggregate, determining the amount of fine aggregate according to the sand rate, and converting the apparent density of the coarse aggregate and the fine aggregate into the mass amount according to the raw material detection data; determining the water quantity required to be added to the concrete mixture, and determining the volume-weight of the concrete mixture ratio according to the mixing amount and the water reducing rate of the water reducing agent and the water content of the sand. The method for preparing high-performance concrete achieves the purpose of high-performance concrete preparation with less raw materials detection, thereby increasing the working efficiency and the reliability, reducing the enterprise cost, and protecting the environment.

Description

technical field [0001] The invention relates to the technical field of concrete preparation, in particular to a preparation method of high-performance concrete. Background technique [0002] With the development of high-rise, large-scale, long-span and modernization of my country's buildings and infrastructure, higher strength and better concrete are required. The traditional domestic concrete mix ratio design methods (such as absolute volume method and assumed bulk density method) are based on The semi-empirical, quantitative and semi-calculation method of empirically determining water-binder (ash) ratio, constant bulk density, and fixed sand-stone ratio can no longer fully meet the performance requirements of modern concrete, and high performance concrete has high durability, high strength, and high workability. It is considered to be the most comprehensive performance concrete in the world, and will become an important construction engineering material in the new century. ...
