Cement base material of humidity-self-regulation

Abstract

The invention discloses a cement basic material with self-adjusting wetness, which is composed of 30-45% cement, 0.3-20% porous adsorbing material, 0.05-1% cement particle dispersing superplasticisers and 45-65% quartz sand. The invention can release water under dry environment, which adjusts air wetness and improves air quality without secondary pollution.

Description

technical field [0001] The invention relates to a cement-based material, in particular to a cement-based material that regulates humidity by absorbing and releasing water vapor. Background technique [0002] Humidity is one of the important factors affecting the comfort of the living environment. Studies have shown that the most suitable humidity environment for the human body is between 40% and 60%. Humidity adjustment can be divided into active and passive according to whether it consumes energy. The former is air-conditioning technology, which is commonly used at present. It consumes a lot of electric energy, pollutes the environment and destroys the ecology, and causes serious indoor air quality problems, which is not in line with the strategy of sustainable development. The passive type uses the moisture absorption and desorption properties of renewable materials to control and adjust the humidity without consuming artificial energy, which is in line with the green che...
