Preparation method of light-shadow image concrete building material

Abstract

The invention discloses a preparation method of a light-shadow image concrete building material. The method comprises the following steps: 1) weighing cement, admixture, aggregate, a polycarboxylate superplasticizer, a water-retaining agent, a thickener and a fiber; 2) placing the weighed raw materials in step 1) in a blender for dry blending, and obtaining concrete slurry by blending for moisturepreservation for standby application; 3) press-buckling an optical fiber line to a semi-grooved silica gel soffit formwork, constructing a light-shadow image, applying epoxy resin to the part, exposed out of the silica gel soffit formwork, of the optical fiber, performing heating curing, performing cooling, casting the concrete slurry with the thickness of 2.5 cm, and performing vibration compacting, demolding and maintenance to obtain a product. Compared with the prior art, the light-shadow image concrete building material prepared with the method has good combination property and visual effect and can be extensively applied to the field of architectural decoration, and the optical fiber material is not prone to separation from a concrete layer.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a method for preparing concrete building materials with light and shadow images. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. [0003] With the improvement of people's living standards, in addition to higher requirements for the performance of bricks and slabs, those skilled in the art will also enrich and change the patterns and colors on ultra-high performance concrete slabs as a new research direction. [0004] Compared with the images printed by color prin...
