Abstract

The invention discloses a concrete stacking forming method. The concrete stacking forming method comprises the following steps of measuring and taking each ingredient according to ingredients of a concrete material; laying measured coarse aggregates into a mold of concrete to be formed to form a coarse aggregate layer; mixing and treating ingredients for preparing mortar with water to prepare themortar; and pouring the mortar into the mold, and performing vacuumizing treatment. The concrete stacking forming method has the advantages that the aggregate distribution uniformity can be effectively improved; the problems of segregation, bleeding, coarse aggregate sinking and the like of liquid concrete are reduced; bubbles possibly remained in a concrete component are reduced; the concrete compactness is improved; the mechanical property and the durability of the concrete are improved; and the consumption of a cementing material can be reduced.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a concrete accumulation molding method. Background technique [0002] Concrete has a history of more than 100 years of development, and it has become the most widely used and used building material in the field of civil engineering worldwide. [0003] At present, ordinary concrete is to use a mixer to mix the cementitious material, sand, admixture and water evenly to obtain a concrete mixture. Although this kind of concrete has the advantages of high compressive strength, easy material acquisition, easy forming, low price, and can be combined with steel to make various load-bearing members, it is also found to have shortcomings in the actual production and application process: for example, the compressive strength is still high. Not ideal. [0004] In addition, in order to facilitate pouring and molding of existing concrete, the concrete mixture is requir...
