Problems solved by technology

Animal protein foaming agent is made of animal hair, tellurium, horn, etc. through sodium hydroxide hydrolysis, the cost of raw materials is extremely high, and the process of preparing animal protein foaming agent is not yet mature, so the application is limited
However, egg yolk, which has a large amount and a wide range and easy access to raw materials, is used as a foaming agent and applied to lightweight foamed concrete products.

Embodiment 1

[0024] 1. Take 100 grams of sulfoaluminate cement, 30 grams of ceramic micropowder, and 50 grams of water, mix and stir evenly to form a concrete slurry.

[0025] 2. Mix egg yolk, NiCl 2 , xanthan gum, phenol, and water are mixed in a weight ratio of 100:3:12:1:2.5, and stirred evenly with a high-speed mixer until uniform and dense foams are formed. Take 200mL of the foam and add it into the prepared cement concrete slurry, stir to make the mixture uniform, and cast it into a mold. After 28 days of curing, the dry bulk density that can be produced is 400kg / m 3 , lightweight foam cement concrete with a compressive strength of 0.8MPa and a thermal conductivity of 0.07W / (m.k).

Embodiment 2

[0027] 1. Take 100 grams of sulfoaluminate cement, 30 grams of ceramic micropowder, and 50 grams of water, mix and stir evenly to form a concrete slurry.

[0028] 2. Egg yolk, FeCl 2 , lignosulfonate, benzoic acid, and water are mixed in a weight ratio of 100:5:10:0.5:3, and stirred evenly with a high-speed mixer until uniform and dense foam is formed. Take 400mL of foam and add it to the prepared concrete slurry, stir to make the mixture even, and pour it into a mold. After 28 days of curing, the dry bulk density can be obtained as 320kg / m 3 , lightweight foam cement concrete with a compressive strength of 0.6MPa and a thermal conductivity of 0.065W / (m.k).

Abstract

The invention discloses a yolk cement concrete foamer and light-weight foaming cement concrete, which comprises the following steps: 1) blending cement, ceramic micro-powder and water evenly according to certain quality; making cement concrete slurry; 2) blending yolk, stabilizer, disperser, conservative and water according to certain weight rate; forming even compact seal-pore foam; weighing certain bulk of foam to add into the cement concrete slurry; stirring evenly; casting; mounding; curing.

Description

(1) Technical field [0001] The invention relates to a lightweight foamed concrete, in particular to an egg yolk cement foaming agent and the lightweight foamed cement concrete thereof. (2) Background technology [0002] my country's annual egg production is about 40 million tons, ranking first in the world. As a common nutritional supplement in daily life, eggs are rich in protein, an essential nutrient for human growth and development, and most of the protein in eggs comes from egg yolk. Egg yolk contains about 15% protein. Because it contains protein foaming ingredients, it has been widely used in food foaming. [0003] At present, most domestic foamed concrete products use synthetic surfactants, vegetable protein foaming agents, and animal protein foaming agents as foaming agents for foamed cement concrete. Synthetic surfactants such as rosin resin, AES, alkylbenzene sulfonate, etc. These foaming agents have good foaming performance, but the foam formed has poor stabil...
