Problems solved by technology

At present, the materials widely used to make lightweight partition boards are polystyrene boards and foam concrete boards. This kind of lightweight partition boards has good thermal insulation performance and waterproof performance, and is light in weight and good in sound insulation. There are also some problems with high-quality partition boards, such as low density, low strength, poor fire resistance, and high prices. Therefore, it is particularly important to reduce costs while improving the quality of lightweight partition boards.
[0004] At present, recycled brick aggregate only partially replaces natural sand and gravel to prepare concrete, but does not completely replace natural sand and gravel in production, and has not fully exerted its use value. If recycled brick aggregate is completely replaced by natural aggregate for production and assembly The dry and hard full brick slag concrete lightweight partition board can maximize the reuse of resources, and make the lightweight partition board have better thermal insulation, sound insulation, high strength and fire resistance effects

Abstract

The invention discloses an all brick slag recycled aggregate concrete light partition board and a making method thereof. Specifically, the host material of the partition board adopts dry hard concreteor semi-dry hard concrete, is internally equipped with a reinforcement skeleton and an anti-crack net, and also has a cavity or solid core internally. The dry hard concrete or semi-dry hard concreteis prepared by mixing of the following raw materials by weight: 8-12 parts of a cementitious material, 4-8 parts of an admixture, 30-40 parts of recycled brick fine aggregate, 40-50 parts of recycledbrick coarse aggregate, 0.05-1.20 parts of an additive, 0.05-0.20 part of fiber, and 4-7 parts of water. The invention has the beneficial effects that: (1) the dry hard concrete or semi-dry hard concrete employs recycled brick aggregate to replace natural aggregate completely, thus effectively utilizing abandoned bricks; (2) the obtained light partition board has better heat insulation, sound insulation, high strength and fire resistance effects, and excellent comprehensive performance; (3) the making process is concise, and is easy to operate, the production efficiency is high, and the repeatability is good.

Description

technical field [0001] The invention relates to a lightweight partition wall panel and a manufacturing method thereof, in particular to a lightweight partition wall panel of whole brick slag recycled aggregate concrete and a manufacturing method thereof, belonging to the technical field of building materials. Background technique [0002] Among industrial solid wastes, construction waste accounts for about 40%, among which waste bricks account for the largest proportion of construction waste. Most of the traditional waste bricks are piled up on the suburban wasteland, causing many serious environmental problems. With the development of research on resource utilization of construction waste, some waste bricks are used for road construction, brick making, etc., and some waste bricks are used as aggregates to partially replace natural aggregates to make recycled concrete, but the added value is low. If we can explore new ways to recycle waste bricks, we will get even greater s...
