Abstract

The invention discloses a method for preparing high strength concrete by using pebbles. The method comprises the following steps: selecting the following raw materials, by weight, 207 parts of cement, 99 parts of water, 87 parts of pebble powder, 3 parts of a water reducer, 37 parts of zeolite powder, 13 parts of carbon nanotubes, 20 parts of fly ash hollow microspheres, 7 parts of fly ash, 27 parts of ore powder, 13 parts of tourmalinite powder, 47 parts of quartz sand, 2 parts of an antifoaming agent, 3 parts of an expanding agent, 19 parts of steel fibers and 3 parts of titanium fibers; mixing, and homogenizing; and carrying out high temperature and high pressure curing. The method enhances the compactness of concrete, and greatly enhances the compressive and flexural strength of the concrete.

Description

technical field [0001] The invention relates to a method for preparing high-strength concrete from pebbles. Background technique [0002] In recent years, high strengthening has become one of the trends in the development of modern concrete technology. The research and development of high-strength concrete has made great progress. The strength of high-strength concrete has gradually increased, its performance has been continuously improved, and it has been widely used in many fields. However, with the complexity of building structures and the increasing number of super high-rise buildings, high-strength concrete can no longer meet the needs of construction, and ultra-high-strength concrete will become the most important trend in the development of concrete. The current high-strength concrete has low compressive and flexural strength. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide a...
