Problems solved by technology

At present, there is no good treatment method for sawdust, and it can only be piled up. The piling up not only causes waste of land and resources, but also pollutes water sources, which is very harmful.

Abstract

High-flexibility leakage-resistant waterproof mortar is prepared from component in weight ratio as follows: 300-500 parts of cement, 100-300 parts of sawdust, 0.5-4 parts of a water-retaining thickener, 5-30 parts of polymer powder, 20-40 parts of bentonite, 0.2-2 parts of a rheological agent, 5-30 parts of an active compound, 1-3 parts of a water repellent, 30-60 parts of ultrafine powder, 0.5-2 parts of an early strength agent and 300-500 parts of sand. A continuous closed polymer film can be formed in the prepared mortar, and the active compound in the mortar can be crystalized and expanded to block capillary channels, so that the mortar has the characteristics of high binding strength, good flexibility, high strength, good leakage resistance, simple preparation process and low cost, can be applied widely to waterproofing and damp proofing of basements, waterproofing of roofs and external walls of buildings, waterproofing of underground garages, integral waterproofing of water tanks and water towers and the like and has large market space and high practicability.

Description

technical field [0001] The invention relates to a highly flexible anti-seepage and waterproof mortar, which belongs to the field of building materials. Background technique [0002] The application of waterproof materials in construction engineering has a long history, but it is more limited to the application of flexible materials such as "coiled materials" and "paints". But at the same time, it also blocks the entry and exit of air in the cement concrete. If the mortar concrete is in an airtight and non-breathing state for a long time, it will only accelerate aging and shorten its life. [0003] The existing ordinary rigid waterproof mortar mainly uses external additives such as water reducing agents, expansion agents, air-entraining agents and waterproofing agents as waterproof materials. Only when the construction thickness is more than 1cm can the waterproof effect be achieved. Not only the construction thickness increases but also the waterproof effect is not good. go...
