C100 high-performance concrete and formulation method thereof

Abstract

The present invention discloses a C100 high performance concrete, which is made of glue material, sand, stone, water and additive; the glue material comprises cement and mixture; the adding amount for the glue material is 500 to 600kg concrete per stere; thereinto, the cement is 42.5; the mixture comprises three components such as silicon powder, coal ash and scoria powder; the active SiO2, the mount of whch is 20 -40 percent of the total weight in the glue material, and the surface area of which is 1000-1200m2 / kg; is included in the glue material, the additive is polymer carboxyl acid with high-efficient dewater ability, the amount of which is 2 - 5 percent of the total glue material; The catalyzer is a mixture consisting of smoke ash and coal waste rock grain, the amount of which are 1-5 percent of the total weight in the glue material. The material does not need high-mark cement with simple produce process and low produce cost; the device can not only enhance the intension of the concrete, but also enhance the working performance and wear ability for the concrete.

Description

technical field [0001] The invention relates to a building concrete material and a preparation method thereof. Background technique [0002] With the development of urban construction and the progress of construction technology, higher requirements are put forward for concrete quality indicators and economic indicators, and the development of concrete is promoted towards high performance such as high strength, light weight, fluidity, and durability. [0003] Especially in the past ten years, due to the development of high-efficiency admixtures and concrete admixture technology, favorable technical conditions have been provided for the preparation of high-strength and high-performance concrete under common process conditions. In the design of some large-scale structures, railway engineering and municipal engineering, more concrete with grades of C50 and C60 appeared. C100 high-performance concrete has also been a hot spot in the research of concrete materials at home and abro...
