Abstract

The invention relates to the technical field of waterproofing of basements, in particular to an environment-friendly energy-saving waterproof material used for a building. The environment-friendly energy-saving waterproof material used for the building is formed by mixing rigid self-waterproof materials and non-woven materials, wherein the rigid self-waterproof materials comprise C35 concrete, coal ash, calcium formate, sodium silicate, magnesium calcium carbonate, aluminium chloride, ferric oxide and a lignosulfonate water reducer, and the non-woven materials comprise hydrophilic fiber nets and water-repellent fiber nets. The water-repellent fiber nets prevent a basement from getting damp, the non-woven materials and the rigid self-waterproof materials are tightly combined through the water-repellent fiber nets, thus the tensile strength is enhanced, the strength, in various directions, of the rigid self-waterproof materials is enhanced, shrinkage stress of concrete is weakened, and capillary passages in the concrete are blocked, so that shrinkage cracks of the concrete are reduced; and the rigid self-waterproof materials prevent a water source on the upper surface from permeatingdownwards, so that the durability of the basement is improved.

Description

Technical field [0001] The invention relates to the technical field of basement waterproofing, in particular to an environment-friendly and energy-saving waterproof material for construction. Background technique [0002] Due to the rapid development of urbanization, the number of residents in the city continues to increase, and people need more and more building area, resulting in more and more scarce urban land resources, so people are pursuing more and more high-rise buildings. Nowadays, urban buildings are generally designed with basements during construction. The basement project is an important part of the underground project of the waterproof building. Because the basement is in a complex and changeable environment, it will often be attacked by various water sources. During the construction process, it will not only be disturbed by groundwater, but also on the ground. The impact of buildings. [0003] Basement waterproofing has always been an important problem faced by peo...
