Abstract

The invention provides a foaming agent for preparation of water-retaining foam concrete. The foaming agent comprises, by weight percent, 10-30% of anionic surfactant, 5-10% of foam stabilizer, 1-10% of water-retaining agent, and 50-80% of water. The anionic surfactant, the foam stabilizer, the water-retaining agent and the water are added into a reaction container according to the specified weight percentage, the temperature is adjusted to 50-90 DEG C for reaction for 1-3 hours, and uniform and transparent liquid is obtained. The water-retaining foam concrete made of the foaming agent has outstanding water retaining effect and unchanged mechanical strength, and is especially suitable for placement of foam concrete in areas with difficulty in water use or subsequent foam concrete maintenance.

Description

1. Technical field

[0001] The invention relates to the field of civil engineering, in particular to a foam agent for preparing water-retaining foam concrete. 2. Background technology

[0002] Foam concrete is a new type of lightweight cement environment-friendly type that uses cement, water, foam (if necessary, can be mixed with fly ash, fine sand, sandy soil, admixture) and other materials, mixed and stirred according to a certain proportion, and solidified. The material has a series of special properties that ordinary concrete does not have, such as light weight, high fluidity, low permeability, self-support after curing, low elastic shock absorption, strength adjustability, heat insulation, and durability. It has become an eye-catching new building material. It has been widely used in the field of thermal insulation in housing construction, and it is also used in engineering projects such as abutment backfill, soft foundation road section filling, and tunnel cavity backfi...
