Embodiment 1～5

[0026] The phosphorus slag-phosphorus tailings foamed concrete blocks of Examples 1 to 5 are prepared by mixing base material, admixture, water and foam. The distribution ratio of each component is shown in Table 1. The base material is composed of phosphorus tailings, Composed of phosphorus slag, lime and cement, the admixture is sodium sulfate (Na 2 SO 4 ), the amount of the admixture is 0.5% of the mass of the base material, the amount of the water is 0.25 of the mass of the dry material composed of the base material and the admixture (the ratio of water to material is 0.25), the Foam is measured by volume, and the ratio of the amount of foam to the total mass of other components (the total mass of base material, admixture and water) is 1600ml / kg.

[0027] The preparation method of phosphorus slag-phosphorus tailings foam concrete block in the embodiment 1~5, comprises the following steps:

[0028] (1) According to the distribution ratio of each component in Table 1, weig...

Embodiment 6～10

[0035] The distribution ratio of each component of the phosphorus slag-phosphorus tailings foam concrete block in Examples 6-10 is shown in Table 2. The base material is composed of phosphorus tailings, phosphorus slag, lime and cement, and the admixture is sodium aluminate (Na 2 Al2 o 4 ), the amount of the admixture is 0.5% of the mass of the base material, the amount of the water is 0.27 of the mass of the dry material composed of the base material and the admixture (the ratio of water to material is 0.27), the Foam is measured by volume, and the ratio of the amount of foam to the total mass of other components (the total mass of base material, admixture and water) is 1200ml / kg.

[0036] In Examples 6-10, the preparation method of the phosphorous slag-phosphorus tailings foam concrete block is roughly the same as that of Examples 1-5, the difference is that the curing in step (3) is under natural conditions for 24 hours, and the cured After demolding the completed test bl...

Embodiment 11～15

[0043] The distribution ratio of each component of the phosphorous slag-phosphorus tailings foam concrete block in Examples 11 to 15 is shown in Table 3. The base material is composed of phosphorous tailings, phosphorous slag, lime and cement, and the admixture is sodium silicate (Na 2 SiO 3 ), the amount of the admixture is 0.5% of the mass of the base material, the amount of the water is 0.3 of the mass of the dry material composed of the base material and the admixture (the ratio of water to material is 0.3), the Foam is measured by volume, and the ratio of the amount of foam to the total mass of other components (total mass of base material, admixture and water) is 1000ml / kg.

[0044] In Examples 11 to 15, the preparation method of the phosphorus slag-phosphorus tailings foam concrete block is roughly the same as that of Examples 1 to 5, the difference is that in step (3), after demoulding the cured test block, place Steamed in an autoclave with a steam pressure of 0.8Mp...

Abstract

The invention belongs to the waste recycle application field, and relates to a phosphorus slag-phosphate tailing foam concrete block and a making method thereof. The phosphorus slag-phosphate tailing foam concrete block is made by using a base material, an additive, water and foam, the base material comprises, by mass, 45-62% of a phosphate tailing, 20-37% of phosphorus slag, 10-18% of lime and 8-10% of cement, and the additive is one or more of sodium sulfate, sodium aluminate and sodium silicate. The phosphorus slag-phosphate tailing foam concrete block is produced in a foam addition mode, the consumption of cement is controlled within 10%, the utilization rate of each of the phosphate tailing and the phosphorus slag is not lower than 72%, and the made foam concrete block has uniform pores, has a heat conduction coefficient of below 0.1w / (m.k), has good heat and sound insulation effects, a high strength and a small weight, and accords with Foam Concrete JGT266-2011 Standard.

Description

technical field [0001] The invention belongs to the application field of waste resources, and in particular relates to a phosphorus slag-phosphorus tailings foam concrete block and a preparation method thereof. Background technique [0002] Foam concrete block is a new type of building material with light weight, certain strength, thermal insulation and noise prevention. With the rapid development of economic construction and the continuous improvement of people's living standards, the energy consumed by buildings is increasing day by day, of which the energy consumption of heating and air conditioning accounts for a large proportion, especially in hot summer and cold winter areas in our country. Energy saving has become the key point of today's building materials Direction of development. Therefore, under the current tense energy supply situation, lightweight building materials are gradually becoming the main body of today's building materials due to their superior energy-...
