Abstract

The invention discloses a cast-in-place lightweight wallboard and a preparation method thereof. The solid components of this cast-in-place lightweight wallboard include the following components by mass: 80-120 parts of cement, 30-50 parts of dried sludge, 10-20 parts of power plant soot, 1-5 parts of shell powder, powder 10-20 parts of coal ash, 0.5-2 parts of fiber, 0.5-2 parts of water reducer, 0.02-0.1 part of foaming agent; wherein, the foaming agent includes the following components: polyacrylamide, polyethyleneimine, poly Vinylpyrrolidone, hydroxypropylmethylcellulose, triethanolamine, surface hydrophilic modified nano-soil powder, surfactant. At the same time, the preparation method of the cast-in-place lightweight wallboard is also disclosed. The cast-in-place lightweight wallboard of the present invention has a simple preparation process, excellent product performance, and has the advantages of light weight, high compressive strength, heat insulation, sound insulation, and water resistance. Compared with the existing lightweight wallboard, the consumption of raw materials The quantity is small, the cost is low, and the application prospect is broad.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a cast-in-place lightweight wallboard and a preparation method thereof. Background technique [0002] With the development of science and technology and the advancement of concrete technology, concrete admixtures have become an indispensable and important component of high-performance concrete materials. By adding chemical admixtures to concrete, the internal structure of concrete can be improved and the performance of concrete can be improved. [0003] Foaming agent, also known as blowing agent, is a substance that can promote foam to form a closed-cell or connected-cell structure. Under certain conditions, through chemical reaction changes or physical methods, it can form a large number of uniform and stable foams in a short period of time. The foaming agent is introduced into the concrete to generate tiny airtight uniform bubbles inside the concrete, w...
