Waterproof mortar taking inorganic minerals as main filler

Abstract

The invention discloses waterproof mortar taking inorganic minerals as main filler. The waterproof mortar is prepared from raw materials of components in percentage by weight as follows: 15%-45% of Portland cement, 1%-10% of attapulgite or modified attapulgite, 1%-7% of active aluminium salt, 0-3% of bentonite, 40%-70% of graded sand, 0.3%-1% of a thickening and moisturizing agent, 0.1%-1% of an early enhancer, 0-1.5% of a retarder and 0-10% of an active activator. The waterproof mortar has good waterproof and anti-seepage performance and is higher in early strength and good in weather resistance, and the later strength is also greatly improved.

Description

Technical field

[0001] The invention belongs to the field of building decoration materials, and specifically relates to a waterproof mortar with inorganic minerals as main fillers. Background technique

[0002] Leakage of buildings will not only damage the interior decoration and equipment of the project, but also seriously damage the structure of the project, causing it to lose its use function, leading to building scrapping and even endangering people's lives. The use of waterproof materials in time to prevent water seepage and water leakage in buildings has been in use since the 1950s.

[0003] Waterproof mortar is a kind of rigid waterproof material, which achieves the purpose of waterproof and impermeable by improving the compactness of the mortar and improving the crack resistance. It is mainly used for waterproofing projects that will not cause harmful cracks due to structural settlement, temperature and humidity changes, and vibration. There are three types of waterproof ...
