Non-bearing type light thin-wall damping partition wall

Abstract

The invention provides a non-bearing type light thin-wall damping partition wall which comprises a wall board formed by an ultrahigh toughness cement-based composite material; the mortar matrix of the ultrahigh toughness cement-based composite material comprises cement, water, fine aggregate, pulverized fuel ash, silica fume, granulated blast-furnace slag and metakaolin, and the mass ratio among the components of the mortar matrix is 1: (0.27-2.2): (0-3): (0-6.9): (0-0.3): (0-0.55): (0-0.4), wherein the maximum particle size of the fine aggregate is not larger than 0.55mm, and the weights of the pulverized fuel ash, the silica fume, the granulated blast-furnace slag and the metakaolin are not equal to 0 at the same time; furthermore, chopped fiber is added into the mortar matrix, and volume dosage of the chopped fiber is 1-3% of that of the wall board; and the slump cone expansion diameter range of the mortar matrix with the chopped fiber is 60-70mm. The non-bearing type light thin-wall damping partition wall effectively replaces the traditional wall board material, and has the advantages of being high in strength, thin in thickness, fire-resistant, impervious, good in durability, low in thermal conductivity, low-carbon, energy-saving and the like.

Description

technical field [0001] The invention belongs to the technical field of new wall materials, and relates to a method for making and assembling a non-load-bearing lightweight thin-wall shock-absorbing partition wall. Background technique [0002] At present, my country's wall materials have shown a diversified pattern, and the innovation and promotion of most building wall materials are aimed at energy saving and low carbon, such as foam concrete, lightweight lime sand bricks, etc. Although such materials have It has the characteristics of light weight and good thermal performance, but it has disadvantages such as low strength, large thickness, easy cracking, and poor durability, which largely limits its application in building walls. Contents of the invention [0003] The object of the present invention is to provide a non-load-bearing lightweight thin-wall shock-absorbing partition wall. This kind of partition wall can effectively replace traditional wall materials, and has...
