Building material prepared by using dredging wastes

Abstract

The invention discloses a building material prepared by using dredging wastes. The building material comprises the following substances in parts by weight: 90-120 parts of dredging wastes, 10-50 parts of cement, 11-25 parts of shells, 3-7 parts of an active resin adhesive, 1-5 parts of wood fiber, 1-3 parts of plant protein cellulose, 30-75 parts of fly ash, 5-17 parts of diatomite, 0.5-3.7 parts of water soluble resin emulsion, 0.56-3 parts of calcium chloride, and 1-3 parts of sodium sulfate. The building material disclosed by the invention has the beneficial effects that low-cost and high-performance products are obtained under the condition of low cost; and the effect of waste utilization is achieved, energy wasting and carbon emissions caused by disposing wastes and transporting raw materials are reduced, and the effects of environmental friendliness and energy saving are improved.

Description

technical field [0001] The invention relates to a construction material prepared from dredging waste. Background technique [0002] At present, building materials such as crushed stones, bricks (including lime-sand bricks), blocks, and plates commonly used in construction have high compressive strength and low tensile strength, and the tensile strength is only about 10% of the compressive strength, resulting in The advantage of its strong ability to resist pressure cannot be fully utilized, which restricts its application. [0003] On the other hand, a large amount of dredged sand is produced every year due to port construction and waterway dredging in coastal areas. At present, there is no good treatment method for these dredged sands, and most of them are thrown outside. The cost of throwing out is relatively high, about 8-15 yuan per square meter, and it will generate a lot of carbon emissions and cause serious environmental pollution. For many coastal and mountainous a...

Problems solved by technology

[0003] On the other hand, a large amount of dredged sand is produced in the coastal area every year due to port construction and waterway dredging. At present, there is no good treatment method for these dredged sand, and most of them are thrown out.

The cost of throwing out is relatively high, about 8-15 yuan per square meter, and will generate a lot of carbon emissions, causing serious environmental pollution

For many coastal and mountainous areas, if the building materials such as crushed stones, bricks, and blocks are transported from other places, the distance is long, the cost is high, and the economy is poor, and long-distance transport will generate a lot of carbon emissions. Pollution of the environment, poor social benefits
