Embodiment 1

[0028] Such as Figure 1-3 As shown, the present invention provides a process for preparing lightweight foamed concrete with high compressive performance. The lightweight foamed concrete with high compressive performance is made of composite concrete and foaming agent, and also includes the following steps:

[0029] Step 1. Prepare composite concrete: first add water to the mixer of the hydraulic foaming machine, then put cement, fly ash, gypsum, water reducing agent and concrete reinforcing agent into the mixer and stir for 0.5 to 2 minutes.

[0030] Step 2, preparing the foaming agent aqueous solution: mixing and stirring the foaming agent foam and water at a weight percentage of 1:25-1:40, thereby preparing the foaming agent aqueous solution.

[0031] Step 3. Preparation of polystyrene foam: adding polystyrene resin to foaming agent, and simultaneously softening with internal heating of the mixer to generate gas to form a polystyrene foam with a rigid closed-cell structure....

Embodiment 2

[0035] Such as Figure 1-3 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, in the step of preparing composite concrete, the mass proportion of cement is 10% to 15%, and the mass proportion of fly ash is 20% to 15%. 30%, the mass proportion of water is 25% to 40%, the mass proportion of gypsum is 15% to 20%, the mass proportion of water reducing agent is 10% to 15%, and the mass proportion of concrete reinforcement is 5% to 15%. %, first mix cement and fly ash according to a certain ratio, then mix with gypsum and water reducer when mixing, and then add water according to the actual ratio to adjust the dilution.

[0036] In this embodiment, by mixing cement and fly ash according to a certain ratio in the step of preparing composite concrete, and then adding gypsum, water reducing agent, and concrete reinforcing agent, the strength of the material is used to increase the strength during the preparation of composite concrete. ...

Embodiment 3

[0038] Such as Figure 1-3 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, in the preparation of polystyrene foam, the mass proportion of polystyrene resin is 10% to 30%, and the mass proportion of foaming agent is 20% to 35%, in the preparation of polystyrene foam, when the polystyrene resin is added to the foaming agent and mixed with the mixer and heated, cooperate with the heating net installed on the inner wall of the mixer, so that when the polystyrene resin and the foaming agent are stirred and mixed, they can be uniform Heating to prepare lightweight foamed concrete, the mass proportion of composite concrete is 40% to 45%, the mass proportion of polystyrene foam is 40% to 45%, and the mass proportion of foaming agent aqueous solution is 5% to 10%, followed by Enter the mixer, stir and mix to prepare light foam concrete, put the foaming agent aqueous solution into the mixer, use the function of heating and stirring t...

Abstract

The invention discloses a preparation process of light foam concrete with high compressive property, and relates to the technical field of building materials. The light foam concrete is prepared from composite concrete and a foaming agent, and the preparation process also comprises the following steps: step 1, preparing the composite concrete: firstly adding water into a stirrer of a hydraulic foaming machine, and then adding cement, fly ash, gypsum, a water reducing agent and a concrete reinforcing agent. In the step of preparing the composite concrete, the cement and the fly ash are mixed according to the proportion, then the gypsum, the water reducing agent and the concrete reinforcing agent are added, the strength is improved during preparation of the composite concrete by utilizing the strength of materials, and a proper amount of water is added in a matched mode to adjust the dilution degree, so that the situation that the strength of the composite concrete is reduced due to excessive water is avoided, the problems that a large number of bubbles are introduced in the manufacturing process of the light foam concrete, the water absorption rate of a base body is easily increased, and the later strength is easily reduced are solved, the strength of the light foam concrete is easily increased, the number of the bubbles is reduced, and the light foam concrete is convenient to use.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a preparation process of lightweight foamed concrete with high compressive performance. Background technique [0002] Foam light soil is to fully foam the foaming agent mechanically through the foaming system of the foaming machine, and evenly mix the foam with the cement slurry, and then carry out cast-in-place construction or mold molding through the pumping system of the foaming machine. It is a new type of lightweight thermal insulation material with a large number of closed pores formed by natural curing. It belongs to the bubble-shaped thermal insulation material. Lightweight soil has been widely used in the field of construction due to its advantages of good durability and light weight. [0003] There are following problems at prior art: [0004] 1. Due to the introduction of a large number of air bubbles in the production process of foam light soil, it is eas...
