Problems solved by technology

At present, the waterproof use of cement-based permeable crystalline materials in the domestic market is far from reaching the foreign level. The main reason is that the difference in the quality of the materials themselves cannot be guaranteed, and the market price also seriously restricts the use of this material. develop

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] see figure 1 , a cement-based permeable crystalline waterproof material, its components and their weight ratios are: 425# ordinary Portland cement: 6# quartz sand: low-alkalinity sulphoaluminate cement: 700-900 mesh talcum powder: 300-500 mesh heavy calcium carbonate: 200-400 mesh anhydrous Na 2 SO 4 : SMD core masterbatch: anhydrous sodium carbonate powder = 490: 370: 62.5: 50: 15: 12.5: 15: 1.5

[0015] When using small-area scraping, the dry powder of the above components can be mixed according to the weight ratio, then mixed with water according to the gray-to-water ratio of 1:0.3, and mixed evenly by manual or mechanical mixing. It is best to use an electric mixer to stir and reconcile. Apply to a thick paste. Strictly implement the construction while mixing. Generally, the amount of powder for each mixing is 3kg, and it will be used up...

Abstract

The invention relates to a cement-based infiltration crystalline waterproof material which comprises the components at the weight ratios as follows: the ratio of 425# ordinary portland cement to 6# quartz sand to low-alkalinity sulphoaluminate cement to talcum powder of 700-900 meshes to ground limestone of 300-500 meshes to anhydrous Na2SO4 of 200-400 meshes to SMD (surface mounted device) core master batch to anhydrous sodium carbonate powder is 490 to 370 to 62.5 to 50 to 15 to 12.5 to 15 to 1.5. The theory durability of the product in the prescription is equivalent to the service life of roof structure concrete; the waterproof purpose is achieved by filling and compacting a gap and a micro-crack of the structure concrete; rusting of a rebar inside the structure also can be delayed; the durability of the concrete structure is improved, and the cement-based infiltration crystalline waterproof material is the cement-based infiltration crystalline waterproof material prescription product with moderate cost, good performance and wide application range.

Description

technical field [0001] The invention belongs to the technical field of building materials and relates to a cement-based permeable crystalline waterproof material. Background technique [0002] At present, more than 90% of domestic houses have been used for more than 10 years. The roof waterproofing has long relied on a single traditional flexible waterproofing solution. Its durability is about 5 to 10 years. And many residents change the design purpose of the roof at will, and plant vegetation on the roof, which aggravates the aging of the waterproof layer and shortens the durability of the waterproof layer. Therefore, the leakage of the roof of the house increases year by year. [0003] The waterproof principle of the cement-based permeable crystalline waterproof material is to fill the pores and micro-cracks of the dense structure concrete to achieve the purpose of waterproofing. Therefore, the waterproof material can also delay the rust of the steel bars in the structure ...
