Inorganic waterproof material with high impervious performance

Abstract

The invention discloses an inorganic waterproof material with a high impervious performance. The raw materials comprise silicate cement, fine river sands, grade I coal ash, silicon powder, an expanding agent and a water reducer. The raw materials further comprise ferric chloride. The inorganic waterproof material comprises the following raw materials in parts by weight: 71-75 parts of silicate cement, 144-152 parts of fine river sands, 11-13 parts of grade I coal ash, 2-4 parts of silicon powder, 11-13 parts of an expanding agent, 3 parts of ferric chloride and 1 part of a water reducer. The material disclosed by the invention has the advantages that the chemical substance ferric chloride is added into the raw materials and the part by weight of the raw materials is adjusted, so that the impervious performance of the waterproof material is improved by 8.16%. In the waterproof material disclosed by the invention, the chemical substance ferric chloride has extremely strong activity and can be quickly reacted with a hydration product of cement to generate insoluble matters so as to effectively block fine holes in mortar, thereby greatly improving the impervious performance of the mortar.

Description

Technical field [0001] The invention relates to a waterproof material, in particular to an inorganic waterproof material with high impermeability. Background technique [0002] The present invention is a further improvement on the basis of the invention patent "Inorganic Waterproof Material" (patent number: ZL 201110045592.5) applied by the applicant in 2011. In the research on the impermeability of cement-based inorganic waterproof materials, it is difficult to solve the mortar water seepage caused by the physicochemical properties and structural defects of the concrete components and the volume shrinkage cracks in the concrete or mortar and the pore structure of the concrete or mortar. problem. In response to the above problems, the applicant selected the raw materials Portland cement, fine river sand, fly ash, silica fume, and added appropriate expansion agents and water reducing agents to prepare a new waterproof material in the patent number ZL 201110045592.5. The waterpro...

Problems solved by technology

However, for the water seepage problem caused by the capillary pores left over from the evaporation of free water in cement mud, the existing waterproof materials cannot meet the requirements of its impermeability performance.
