Abstract

The invention discloses a glass fiber reinforced concrete material. The glass fiber reinforced concrete material is characterized by being prepared from the following raw materials in parts by weight:30-40 parts of cement, 2-5 parts of zircon sand, 10-15 parts of surface-grafted beta-cyclodextrin glass fibers, 3-6 parts of waste gypsum, 10-20 parts of volcanic ash, 20-30 parts of gravels, 60-80 parts of fine river sand, 4-8 parts of sulfate-containing organic silicon microspheres, 3-6 parts of additives and 15-20 parts of water. The glass fiber reinforced concrete material also comprises thefollowing preparation raw materials: 3-6 parts of rare earth fluoride nanofibers and 1-3 parts of zinc oxide mesoporous nanofibers. The invention also provides a preparation method of the glass fiberreinforced concrete material. The glass fiber reinforced concrete material disclosed by the invention is good in interface bonding effect and compatibility among the components, good in comprehensiveperformance, high in toughness and bending strength, and excellent in durability and impermeability.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a glass fiber reinforced concrete material and a preparation method thereof. Background technique [0002] With the development of society, there are more and more buildings and construction projects of all kinds, driving the concrete material industry to advance by leaps and bounds. Concrete material is the most widely used building material in modern times, and it is also the largest man-made material at present. Compared with other commonly used building materials, concrete material has low energy consumption, wide source of raw materials, simple process, low production cost, and durable , fire prevention, strong applicability, convenient application and so on. With the improvement of people's safety awareness and the increase of special requirements for modern construction projects, higher requirements are put forward for the performance of concrete materials.
