Problems solved by technology

However, due to the shortcomings of concrete such as low tensile strength, high brittleness, and easy cracking at high temperatures, its structure will eventually have its service life, which limits the wider application of concrete and intensifies the maintenance of concrete in the later stage. At the same time, a large number of concrete Since the buildings cannot be maintained, they need to be dismantled after reaching the service life, which not only becomes a lot of waste, pollutes the environment, but also wastes a lot of resources.

Embodiment 1

[0025] figure 1 It is a structural schematic diagram of a novel synthetic concrete material of the present invention. It can be seen from this figure that a novel synthetic concrete material of the present invention consists of a concrete body 1, a concrete surface layer 2, and a glass fiber geogrid 3 between the concrete body 1 and the concrete surface layer 2.

[0026] The fiberglass geogrid 3 is a planar grid-like material constructed on the basis of glass fibers, and the fiberglass geogrid 3 is laid between the concrete body 1 and the concrete surface 2, and the adhesive layer oil is used to 4 are fixedly connected with the concrete main body 1 and the concrete surface layer 2 respectively. In this embodiment, the thickness of the glass fiber geogrid 3 is 60-100 mm, and the thickness of the concrete surface layer 2 is 60-100 mm.

[0027] The mass of the glass fiber geogrid 3 is 0.03%-0.055% of the total mass of the new synthetic concrete material, and the mass of the adh...

Embodiment 2

[0039] Embodiment 2: The weight percentage of cement, river sand, gravel, and water is 1:2:3:0.6. The mass of the glass fiber geogrid 3 accounts for 0.055% of the total mass, and the mass of the sticky layer oil 4 accounts for 0.025% of the total mass of the new synthetic concrete material.

Embodiment 3

[0040] Embodiment 3: The weight percentage of cement, river sand, gravel, and water is 1: 1.6: 2.7: 0.5. The mass of the glass fiber geogrid 3 accounts for 0.045% of the total mass, and the mass of the sticky layer oil 4 accounts for 0.02% of the total mass of the new synthetic concrete material.

Abstract

The invention discloses a novel synthetic concrete material and a preparation method and belongs to the field of concrete. The novel synthetic concrete material is prepared from glass fiber geogrid reinforced concrete. The preparation method is characterized by comprising the steps of mixing cement, water, river sand and pebbles in proportion, and conducting reinforcement treatment on compaction molded concrete through glass fiber geogrid to form the high-performance synthetic concrete material. The novel synthetic concrete material manufactured through the method has high tensile resistance,high elastic tension, good heat resistance, good corrosion resistance, low ductility, stable chemical property and good integration.

Description

technical field [0001] The invention relates to a new type of building material with high performance, more specifically, it is a new type of concrete material reinforced with glass fiber geogrid. belongs to the field of concrete. The invention also relates to a method for the preparation of this novel synthetic concrete material. Background technique [0002] With the continuous development of industrial technology, the demand for building materials has gradually increased, and the requirements for the performance of building materials have also increased. In today's life, concrete has become the most widely used building material due to its advantages of simple operation and low cost. However, due to the shortcomings of concrete such as low tensile strength, high brittleness, and easy cracking at high temperatures, its structure will eventually have its service life, which limits the wider application of concrete and intensifies the maintenance of concrete in the later s...
