Concrete strutting piece and preparation technology thereof

The invention relates to a concrete strutting piece and a preparation technology thereof, belonging to the technical field of construction strutting piece. The concrete strutting piece is characterized in that a strutting piece body is a cuboid, a reinforcement steel bar slot is formed in the top surface of the strutting piece body, the length (L) of the strutting piece body is adaptive to the thickness of a building wall body, and the strutting piece body comprises raw materials: cement, aggregate chips and water the mass ratio of which is 100:480-550:43-63; the aggregate chips with particle size D of no more than 0.1cm accounts for 30-40% of total amount of aggregate chips. According to the technology, a reinforcement steel bar slot is formed in the side surface, and demolding and maintenance are immediately conducted after pressing is conducted for 1-4s. The strutting piece is short in maintenance time, high in early strength, adaptive to concrete of buildings, convenient and fast in technological process,
