Embodiment approach 1

[0015] I. adopt, slag, fly ash, river sand, lime, cement material are as initial material, and initial formula is: cement 530kg, middle sand 348kg, gravel 845kg, water: 220kg;

[0016] II. The ingredient scheme is as follows:

[0017] Cement: 424kg, medium sand: 348kg, gravel: 845kg, slag: 53kg, fly ash 53kg, water-cement ratio: 1:0.3, waste fiber: fiber volume accounts for 2% of the total material volume;

[0018] III. Optimization and determination of combined integrated block structure

[0019] There are no special requirements and restrictions on the size and shape of the test block, which can be determined according to actual needs. Generally, it is 36×24×18.5cm, and the molding pressure is 20KN. After molding, it should be cured under natural conditions and heat preservation conditions. After 28 days, Carry out a pressure test with a strength of 25MP.

Abstract

The invention discloses a preparation method of a building material containing waste fibers, belongs to the field of buildings and materials, and is characterized in that the preparation method achieves the comprehensive utilization of fly ash, furnace slag and waste fibrous materials and produces environment-friendly and energy-saving fiber building materials. The raw materials used comprises cement, sand, gravels, fly ash, furnace slag, waste cotton yarns from textile industry, waste fabric strips from garment industry, leftover materials and water. The building material is a building block which is available in different shapes according to the actual needs and can be freely assembled and connected. If necessary, the building block can be a structure provided with a dovetail-shaped mortise and a tenon. The preparation method realizes the comprehensive utilization of fly ash, furnace slag and waste fibrous materials, and achieves the purposes of turning harm into benefit and turning waste into treasure. Besides, the flexibility and the strength of building wall materials are improved, and the problem of imbalance between supply and demand is solved.

Description

technical field [0001] The invention relates to a method for preparing building materials containing waste fibers, which belongs to the field of construction and materials, and specifically relates to an environment-friendly and energy-saving fiber building material prepared by utilizing industrial waste residue and waste fiber materials and a preparation method thereof. Background technique [0002] The rapid development of my country's economic construction requires a lot of building materials, but the production of clay bricks not only destroys my country's limited land resources, consumes a lot of energy, but also emits a lot of SO 2 and greenhouse gases, polluting the atmosphere. Therefore, the use of solid clay bricks is first banned in 170 large and medium-sized cities in my country. The current annual discharge of fly ash and slag in the country is about 110 million tons. In addition to the fly ash and slag that have not been used for many years, the cumulative stoc...
