Description

technical field [0001] The invention belongs to the technical field of building materials, and particularly relates to a concrete slurry and a preparation method thereof. Background technique [0002] Concrete is a building material, which is made by mixing cement, sand, stone aggregate and water in proportion, and admixtures and admixtures can also be added. It has the advantages of easy molding and low price. Traditional concrete has poor bonding ability, limited strength and durability, which limit the load-bearing capacity and construction use of concrete. Chinese patent CN107540291A discloses a concrete slurry and its preparation method, which are prepared by using natural sand, silt ceramsite, cement, water, water reducing agent, thickener and air-entraining agent; the concrete slurry adopts silt ceramsite as the Aggregate can realize the recycling of waste resources. The concrete specimen has good compressive strength, low density and good mechanical properties, but ...
