Embodiment 1

[0031] The high-strength active powder fiber concrete slab provided by this embodiment includes water and ingredients with a water-binder ratio of 0.28-0.36. The water-binder ratio can be selected from the most suitable value in the range of 0.28-0.36 according to different requirements to ensure The final product has the most suitable hardness and is easy to manufacture. For the same ingredients, the smaller the water-binder ratio, the greater the hardness of the final product, but the production efficiency is relatively reduced. The proportioning (weight ratio) of each composition of batching is: 40% of quartz powder, 30% of 42.5# cement, 3% of plant fiber, 3% of alkali-resistant glass fiber, 5% of nano-scale silicon powder, 18% of fly ash and Polyacrylic acid superplasticizer 1%; the concrete slab is a multi-layer structure, one surface of which is provided with a fibrous polymer mesh layer, this surface is the bottom surface of the concrete slab, and an alkali-resistant gla...

Embodiment 2

[0033] The high-strength reactive powder fiber concrete slab provided by the present embodiment differs from Example 1 in that the proportioning (weight ratio) of each ingredient of the batching is: 35% of quartz powder, 30% of 42.5# water, 3% of plant fiber, 3% of alkali-resistant glass fiber, 8% of nano-scale silica fume, 20% of fly ash and 1% of polyacrylic superplasticizer. The amount of fly ash used as a mineral additive. Fly ash has good fluidity, which can promote the uniform and full reaction of each component of the raw material during the reaction, improve the efficiency of the raw material reaction, and facilitate manufacturing.

Embodiment 3

[0035] The high-strength active powder fiber concrete slab provided by the present embodiment differs from Example 1 in that the proportioning (weight ratio) of each ingredient of the batching is: 35% of quartz powder, 35% of 42.5# water, 3% of plant fiber, 3% of alkali-resistant glass fiber, 5% of nano-scale silica fume, 18% of fly ash and 1% of polyacrylic superplasticizer. The products obtained by using this ratio can meet the general needs on the premise of ensuring other properties , has high strength, and is suitable for special environments that require high wall strength.

Abstract

The invention relates to a high-strength active powder fiber concrete slab characterized by comprising the following components of water with the water to binder ratio of 0.28-0.36 and ingredients, the ingredients comprise the following components in proportion (proportion by weight): 35-40% of quartz powder, 30-35% of cement, 6% of fibers and 24-29% of reaction assistants, wherein the fibers are vegetable fibers or/and alkali-resistant glass fibers; and the reaction assistants comprise 23-28% of mineral assistants and 1% of chemical assistants, wherein the mineral assistants are nano silica powder or/and pulverized fuel ash, and the chemical assistants are polyacrylic acid-series superplasticizers. Through synthesizing the characteristics of various materials, the finally obtained high-strength active powder fiber concrete slab has the advantages of light weight for lightening the weights of buildings, convenient transportation for improving the construction speed and shortening the construction period, fire and moisture prevention, heat insulation, good sound insulation and weather resistance, weathering resistance, acid rain resistance, ultraviolet ray resistance, no toxicity, no radiation and the like, can thin wall bodies to increase the usable areas of floors, and has light dead weight and good earthquake resistance so as to be beneficial to developing high-rise buildings and saving urban lands.

Description

Technical field [0001] The invention belongs to the field of construction, specifically a high-strength active powder fiber concrete board with high strength, high peeling force, thermal conductivity, good stability, and environmental protection. Its physical properties fully meet the high impact resistance of exterior walls, floors, and interior walls. , High demolition resistance requirements; the present invention also relates to the manufacturing method of the above-mentioned high-strength active powder fiber concrete board. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for walls used in life and production. It is hoped that walls have various comprehensive properties such as heat preservation, sound insulation, and compression resistance. At present, in the field of construction, boards are often spliced ​​together to form a complete wall, so the performance of the board directly determines the perform...
