Embodiment 1

[0025] The preparation of modified bamboo fiber reinforced aerated concrete, the concrete steps are:

[0026] 1) Bamboo fiber modification process: Weigh 3.2g of bamboo fiber and dry it in an oven at 103°C to a constant weight for later use; prepare a KH560 ethanol solution with a concentration of 1 wt% as a modifier, and the amount of KH560 is 10% of the quality of the bamboo fiber. ; Take ethylenediamine as the catalyst, and its dosage is 10% of KH560. Take an appropriate amount of bamboo fibrils, stir the modifier solution and bamboo fibrils in a constant-temperature heating magnetic stirrer at 60°C for 3 hours to ensure that the fibers are in full contact with the modifier, wash the modified fibers with water and put them in an oven for drying (103 ℃, 24h), sealed in a vacuum bag and stored for later use.

Using γ-glycidyl etheroxypropyl trimethoxysilane (KH560) to modify bamboo fiber, the prepared modified bamboo fiber reinforced aerated concrete is environmentally friendly, has good physical and mechanical properties, and is popularized The application prospect is huge.

Description

technical field [0001] The invention belongs to the technical field of fiber-reinforced aerated concrete, and particularly relates to a modified bamboo fiber-reinforced aerated concrete and a preparation method thereof. Background technique [0002] In recent years, green environmental protection and sustainable development have become the research hotspots of wall materials. Air-entrained concrete is a kind of lightweight porous concrete, which is made of calcareous material, siliceous material, gas-generating agent, water, etc. A new type of wall material. Using a single porous concrete material for wall enclosure can achieve the requirement of 65% of building energy saving. Due to the increasing shortage of river sand resources, the current industry tends to use high SiO 2 content of mineral waste residue as siliceous material. During the processing of granite stone, a large amount of powder waste is generated due to cutting, grinding and other processes, and its SiO ...
