Problems solved by technology

[0002] In recent years, raw soil buildings have attracted people's attention again due to their environmental protection, excellent thermal insulation performance, and low construction cost. More and more scholars have begun to study the modification of raw soil buildings. However, the existing raw soil modified materials Most of them use water as the binder and single-mixing as the basic scheme. Most of them are mixed with fly ash, wheat straw, desulfurization waste and other materials, which slightly improve the compressive strength, earthquake resistance, shear resistance and other properties of raw earth buildings. But it doesn't do much for the deformability of earthen buildings

Embodiment 1

[0035] The present embodiment provides a kind of modified raw soil material, by weight unit, is made up of following raw material: 100 parts of raw soil, 5 parts of glass slag, 0.2 part of bamboo fiber, 13 parts of glutinous rice pulp, wherein water 100 parts when making glutinous rice pulp 3 servings of glutinous rice. Preparation:

[0036] Weigh 2kg of water, mix 60g of glutinous rice with water, and cook for about 25 minutes until boiled;

[0037] The glutinous rice is filtered, and the glutinous rice slurry is cooled, and the glutinous rice slurry of 13% of the raw soil quality is weighed;

[0038] The glass is pulverized, sieved with a 5mm sieve, and weighs 5% glass slag of raw soil quality;

[0039] Bamboo fiber is pulverized, chooses the bamboo fiber of 1~2cm length, takes the bamboo fiber of 0.2% of raw soil mass;

[0040] Mix raw soil, glutinous rice pulp, glass slag, and bamboo fiber to obtain the modified raw soil material of this embodiment.

Embodiment 2

[0042] The present embodiment provides a kind of modified raw soil material, by weight unit, is made up of following raw material: 100 parts of raw soil, 10 parts of glass slag, 0.5 part of bamboo fiber, 13 parts of glutinous rice pulp, wherein water 100 parts when making glutinous rice pulp Part, 3 parts of glutinous rice, preparation method is the same as embodiment 1.

Embodiment 3

[0044] The present embodiment provides a kind of modified raw soil material, by weight unit, is made up of following raw material: 100 parts of raw soil, 15 parts of glass slag, 0.8 part of bamboo fiber, 13 parts of glutinous rice pulp, wherein water 100 parts when making glutinous rice pulp Part, 3 parts of glutinous rice, preparation method is the same as embodiment 1.

Abstract

The invention provides a modified raw soil material, which comprises the following raw materials in terms of weight unit: 100 parts of raw soil, 5-15 parts of glass slag, 0.2-0.8 part of bamboo fiber, and 13 parts of glutinous rice slurry. The formula involved in the invention can improve the ductility and deformation ability of raw soil test pieces to a large extent, and prolongs the time to failure of the test pieces. In real life, the earthquake-resistant time of raw soil buildings can be prolonged, and the resident life and property loss can be reduced. Under the circumstance of no compound addition scheme in the prior art, the invention creatively proposes the compound addition conception, the glutinous rice slurry is taken as the adhesive, and glass slag and bamboo fiber are added in raw soil to modify it. The formula improves the compressive strength, deformability and time to failure of raw soil buildings.

Description

technical field [0001] The invention belongs to the field of building materials and relates to raw soil materials, in particular to a modified raw soil material. Background technique [0002] In recent years, raw soil buildings have attracted people's attention again due to their environmental protection, excellent thermal insulation performance, and low construction cost. More and more scholars have begun to study the modification of raw soil buildings. However, the existing raw soil modified materials Most of them use water as the binder and single-mixing as the basic scheme. Most of them are mixed with fly ash, wheat straw, desulfurization waste and other materials, which slightly improve the compressive strength, earthquake resistance, shear resistance and other properties of raw earth buildings. But not much has been done in terms of the deformability of adobe buildings. Contents of the invention [0003] In view of the deficiencies in the prior art, the object of th...
