Embodiment 1

[0027] A self-leveling lightweight aggregate made of raw materials in the following weight percentages:

[0028] Component Weight percentage / %

[0029] Desulfurized gypsum or construction gypsum 74

[0030] Portland cement 8

[0031] Mineral powder 8

[0032] Perlite or polystyrene pellets 9

[0033] Defoamer 0.1

[0034] Methylcellulose 0.2

[0035] Coagulant regulator 0.2

[0036] Water reducer 0.2

[0037] Water repellent 0.3

[0038] The self-leveling is obtained by mixing the above components evenly. When the self-leveling is used, the amount of water added is 40% of the weight of the self-leveling.

[0039] Preferably, the gypsum is one of desulfurized gypsum and construction gypsum.

[0040] Preferably, the lightweight aggregate is one of perlite and polyphenylene particles.

[0041] Preferably, the defoamer is one of polyether type and silicone type.

[0042] Preferably, the coagulation regulator is one of citric acid, glucose or boric acid.

Abstract

The invention discloses a self-leveling agent of light aggregate. The self-leveling agent is prepared from gypsum, silicate cement, mineral powder, light aggregate, a defoaming agent, methylcellulose, a thickening time control agent, a water reducer, and a waterproof agent. The self-leveling agent has the beneficial effects that the price is low, the weight is light, and the heat insulation and isolation effects are realized; the self-leveling agent can be used for the construction of heating floors and partition walls; the fluidity is good, and the construction is convenient.

Description

technical field [0001] The invention relates to building materials, in particular to a self-leveling lightweight aggregate. Background technique [0002] Self-leveling is a ground construction technology, usually composed of cement-based cementitious materials, fine aggregates, fillers and additives, etc. After mixing with water or emulsion, it has a certain fluidity, and can be poured into the ground according to the unevenness of the ground. Flow along the trend and automatically level the ground. Traditional cement or gypsum self-leveling does not have excellent thermal insulation and heat insulation effects. However, energy saving and environmental protection are one of the basic national policies of our country. Therefore, the country is promoting the requirements for environmental protection and energy saving of buildings. Combined with the construction requirements of floor heating or partition walls, a lightweight, environmentally friendly and easy-to-construct mate...
