Problems solved by technology

[0005] However, when wastes such as fly ash and blast furnace slag are added, although it can reduce the amount of cement and reduce production costs, due to the large amount of harmful substances remaining in fly ash and blast furnace slag, the waste of fly ash The quality is poor and the radiation is large, which leads to the poor quality of the produced products, poor thermal insulation performance, poor sound insulation effect, and also brings pollution to the air. For this reason, the researchers combined fly ash and blast furnace water The colloidal substances contained in the slag, and the existence of these colloidal substances can increase the strength of the product, reduce the amount of cement, and even eliminate the use of cement, and then obtain a slurry similar to concrete, and then make the slurry into Wall products, and then can obtain higher strength, longer time refractory materials, and then provide a new way for the field of foamed concrete wall material production

Abstract

The invention relates to the technical field of concrete panel material, and especially relates to a foaming concrete panel and a preparation method thereof. According to the combination and ratio of fly ash, blast furnace water slag, river sands, a foaming agent, fiber and a fly ash foaming agent, a depolymerization reaction and a polymerization reaction are carried out on the raw material substances, raw material performance can be performed, raw materials performance can be combined for controlling, raw materials performance is better, foaming processing of the raw materials can be enhanced, restriction of fly ash, a foaming agent and a fly ash foaming agent can ensure the mutual modification processing of the raw materials, crosslinking effect of the raw materials are enhanced, flexural compressive strength of the products can be enhanced, foaming concrete panel quality is increased; subsequent preparation technology and technological parameter are combined, so that raw material performance can be improved, and product quality is increased.

Description

technical field [0001] The invention relates to the technical field of concrete wallboard materials, in particular to a foamed concrete wallboard and a preparation method thereof. Background technique [0002] With the popularization of building energy saving and the continuous improvement of people's demand for the comfort of living environment, thermal insulation materials have been paid more and more attention by people. As one of the house insulation materials, the room temperature non-fired foamed brick is mainly made of cement, slag powder, river sand, etc. as raw materials. After mixing, it is foamed by pressure air, and the air is forced into the mixed slurry to form micro-bubbles. The structural concrete is molded and made through autoclave reaction and other processes. It is a new type of wall material that is environmentally friendly, energy-saving, and stable in material. Because of its thermal insulation, sound insulation, fire prevention, and strength superior...
