Embodiment 1

[0015] Embodiment 1: Preparation and performance characterization of materials

[0016] Weigh the raw materials, first foam the foaming agent evenly, add the weighed water, and add white cement, mix and stir for 30-60 seconds, add the pre-wet ceramsite, then add the inorganic iron red pigment, and stir for 30-60 seconds 60s, molded. After 28 days of molding and curing, the sample is red ceramsite foam concrete with a volume density of 653kg / m 3 , the compressive strength is 2.9MPa, and the thermal conductivity is 0.37W / m·K. According to the standard "Foam Concrete" JG / T266-2011, the strength of foam concrete with the same density grade is 1.0-1.5MPa.

Embodiment 2

[0017] Embodiment 2: Preparation and performance characterization of materials

[0018] Weigh the raw materials according to Example 1, first foam the foaming agent evenly, add the weighed water, and add white cement, mix and stir for 30-60 seconds, add the pre-wet ceramsite, and then add the inorganic iron yellow pigment , Stir for 30-60 seconds, and mold it. After 28 days of molding and curing, the sample is yellow ceramsite foam concrete with a volume density of 725kg / m 3 , the compressive strength is 3.7MPa, and the thermal conductivity is 0.42W / m·K. According to the standard "Foam Concrete" JG / T266-2011, the strength of foam concrete with the same density grade is 1.2-2.0MPa.

Abstract

The invention provides colorful ceramsite foam concrete and a preparation method thereof. The colorful ceramsite foam concrete is prepared from, by weight, 0.5-3 parts of inorganic pigment, 35-45 parts of white cement, 15-25 parts of water, 20-45 parts of ceramsite and 2-5 parts of a foaming agent, wherein the strength grade of the white cement is 42.5, the particle size of the ceramsite is 5-20 mm, the bulk density of the ceramsite is 500-800, the cylinder pressure strength of the ceramsite is 3-5 MPa, and the inorganic pigment is inorganic metal oxide pigment; the foaming agent is foamed uniformly and added into the weighed water, the white cement is added, mixing and stirring are performed for 30-60 seconds, the pre-wetted ceramsite is added, then the inorganic pigment is added, stirring is performed for 30-60 seconds, and mold filling is performed for forming. The colorful ceramsite foam concrete has the characteristics of heat preservation, heat insulation and high strength, meanwhile has a decorative effect, can be used as an exterior wall, does not need heat-preservation and decoration construction, achieves the effect of integrating heat preservation and decoration and meets practical and industrial conditions.

Description

【Technical field】 [0001] The invention relates to a colored ceramsite foam concrete and a preparation method thereof. 【Background technique】 [0002] Ceramsite foam concrete is a kind of man-made material mixed with lightweight ceramsite and foam concrete (water, cement, fly ash, special cement foaming agent, special coagulation accelerator). Combining the advantages of ceramsite and foam concrete, overcoming the shortcomings of a single product, the foam concrete ceramsite block has light apparent density, high strength, excellent thermal insulation performance, small shrinkage, low water absorption, and impermeability Strong, good frost resistance, excellent fire resistance and durability, good sound insulation and sound absorption, and good shock resistance and shock absorption are the main reasons. At present, ceramsite foamed concrete is prepared by ordinary Portland cement. Its color is cold and dark, lacks color, and is not suitable for decoration, thus restricting i...
