Abstract

The invention discloses ceramsite foam concrete and a preparation process thereof. The concrete comprise the following components in parts by weight: cement, fine sand, reinforced lightweight aggregate, polypropylene resin fiber, fly ash, mineral powder, a waterproof agent, an air entraining agent, a foaming agent, a water reducing agent and water. The preparation process includes the following steps: S1. weighing corresponding parts of the cement, the fine sand and ceramsite, and putting the above components into a stirrer for stirring; S2. weighing corresponding parts of the polypropylene resin fiber, the fly ash and the mineral powder, adding the polypropylene resin fiber, the fly ash and the mineral powder into the stirrer in the step S1 to continuously stir and mix, adding the water in two thirds of the proportioning parts, and continuously stirring and mixing to form slurry with uniform color; S3. adding the water, the waterproof agent, the air entraining agent and the water reducing agent with the remaining parts into the step S2 to continue stirring, starting a pressure foaming machine at the same time, and adding foam generated by the foaming agent with corresponding partsinto the slurry; and S4. uniformly stirring and mixing the slurry and foam in the step S3. The ceramsite foam concrete has the advantages of high compressive strength, good impermeability and good durability.

Description

technical field [0001] The invention relates to the technical field of concrete production, in particular to a ceramsite foam concrete and a preparation process thereof. Background technique [0002] Foamed concrete, also known as foamed cement, lightweight concrete, etc., is a new type of building energy-saving material that is waste-friendly, environmentally friendly, energy-saving, inexpensive and non-combustible. Foam concrete (lightweight concrete) is formed by introducing air or nitrogen, carbon dioxide, oxygen and other gases into the concrete slurry according to the application needs through chemical or physical means, and after reasonable maintenance and molding, it is formed to contain a large number of small closed pores, and Concrete products of considerable strength. Because the foam concrete contains a large number of closed small pores, it has good thermal insulation performance, and at the same time, a large number of small void structures also make the foam...
