Abstract

The invention relates to a lightweight energy-saving insulating concrete, belonging to building materials. The invention comprises the master batches and accessories in accordance with the following parts by weight: master batches: 30-70 parts of cementing materials, 25-60 parts of fillers, 5-10 parts of strength activators, and accessories: 1-3 parts of waterproof agents, 2.0-3.0 parts of bleeding agents, 2.0-5.0 parts of suspending agents, 0.1-0.5 part of foam stabilizer, 38-60 parts of honeycomb agents, 0.5-1.5 parts of rusty retardant agents, 0.02-10 parts of reinforcing agents, 1.2-4.2 parts of early strength agents and expanding agents and 0.6-1.4 parts of acid and alkali resistant fibers. The concrete has the advantages of high early tensile and compressive strength, no decrease and crack of later strength and simple manufacturing process. According to the requirement of the building structure, the technical target of the concrete can be realized by regulating the mixing proportion. The concrete can be used for manufacturing various products at normal temperature and is widely applied to insulating and self-waterproof building engineering.

Description

technical field [0001] The invention belongs to a building material, in particular to a lightweight energy-saving thermal insulation concrete. Background technique [0002] Promoting the innovation of wall materials and promoting energy-saving buildings are important measures to improve building functions, improve resource utilization efficiency and protect the environment.
