Energy storage material using concrete waste and preparation method thereof

Abstract

The invention relates to an energy storage material using concrete waste and a preparation method thereof. The energy storage material is prepared by mixing the following components in parts by mass:10.1-14.0 parts of ordinary portland cement, 35.0-42.0 parts of concrete waste coarse aggregate, 31.5 -37.3 parts of concrete waste fine aggregate, 3.5-4.0 parts of fly ash, 3.5-4.0 parts of slag powder, 1.5-4.0 parts of steel fiber, 0.1-0.15 part of organic fiber, 1.0-3.0 parts of carbon fiber, 6.7-7.5 parts of water and 0.3-0.7 parts of water reducing agent. That concrete heat storage material has features of simple preparation process, easy availability of raw materials, low cost, good heat storage performance, good workability, high strength and non-cracking.

Description

technical field

[0001] The invention relates to the field of energy storage materials, in particular to an energy storage material using concrete waste and a preparation method thereof. Background technique

[0002] In recent years, environmental pollution has been serious, especially in northern areas where smog is raging. In order to control the environment, the state has issued a series of policies to promote the development of clean energy. Among them, solar energy, as a green, pollution-free, renewable clean energy, has The inexhaustible characteristic has attracted extensive attention of researchers. At present, thermal energy storage technology is one of the main technologies for solar energy utilization, that is, when the sunlight is sufficient, the energy is stored in the form of thermal energy in the energy storage material, and when the sunlight is not sufficient, the energy is released for life or production needs. The key to energy storage technology is energy ...
