Abstract

The invention belongs to the technical field of concrete, and discloses nano foam glass bead concrete capable of being used for a door plate and a preparation method of the nano foam glass bead concrete. The nano-foam glass bead concrete is prepared from the following components: an admixture, nano-foam, a cementing material and water, the admixture comprises polyvinyl alcohol fibers and glass beads. The density of the nano-foam glass bead concrete can be obviously lower than 1000 kg / m < 3 > of foam concrete in the prior art, even as low as 700 kg / m < 3 >, and when the density of the nano-foam glass bead concrete is as low as 700 kg / m < 3 >, the compressive strength of the nano-foam glass bead concrete in 7 days can still reach 4.0 MPa and is far higher than the compressive strength of other foam concrete in the market. In addition, the nano foam glass bead concrete also has good fireproof, heat-insulating and sound-insulating effects.

Description

technical field [0001] The invention belongs to the technical field of concrete, and in particular relates to a nano foam glass bead concrete which can be used for a door panel and a preparation method thereof. Background technique [0002] Foam concrete is made by mechanically foaming the foaming agent to obtain foam, and then adding the foam into the cement-based cementitious material, mixing evenly, pouring and molding, and finally curing to form a microporous lightweight material. The outstanding advantage of foam concrete is that the foam holes formed in the concrete make the high-density cement concrete lightweight and functional, thus endowing the concrete with various functions such as light weight, heat preservation, heat insulation, sound insulation, fire prevention, and corrosion resistance. , thus opening up a special field of application for concrete. [0003] As a new type of inorganic fireproof and thermal insulation material, foam concrete generally has defe...
