Phase-change-energy-storage phase change concrete and preparation method

Abstract

The invention provides phase-change-energy-storage phase change concrete and a preparation method. The phase change concrete comprises the following components according to part by weight: 90 parts of ordinary silicate cement, 10 parts of rapid hardening sulphoaluminate cement, 1-1.5 parts of water reducer, 0.5-1 part of accelerating agent, 0.5-1 part of early strength agent, 50-70 parts of water and 10-20 parts of phase change energy storage materials, and the volume (liter) of foam accounts for 300%-500% that of the added water. In the preparation process, cement slurry is stirred uniformly and then stands for 20min-30min, and then the foam is added in the cement slurry. A wall body made by the concrete has high heat insulation performance and electric insulation performance, low unit weight and water absorption, and also has automatic temperature adjusting function under the premise of ensuring the strength.

Description

Technical field [0001] The invention relates to the field of construction technology, in particular to a phase change energy storage phase change concrete with good thermal insulation performance and temperature adjustment performance and a preparation method. Background technique [0002] Energy and environment are the key issues that the current society is paying attention to. With the development of the construction industry, how to reduce building energy consumption and improve the living environment has received widespread attention. [0003] Foamed concrete is also called foamed concrete. Its most notable feature is the formation of air bubbles in the concrete, which makes the concrete lightweight, heat preservation and heat insulation. Compared with other warm materials, foam concrete has low price and readily available raw materials. It can be quickly cast in place and can be made into various products. At the same time, it has fire resistance, sound insulation, earthquake...

AI Technical Summary

Problems solved by technology

However, the heat capacity of ordinary lightweight building materials is small, leading to large fluctuations in indoor temperature and poor indoor environment comfort. At the same time, it also increases the load of heating and air conditioning systems, resulting in increased building energy consumption.
