Abstract

The invention discloses a cement-based crystal master batch material and a preparation method. The material is prepared from, by weight, 0.5-0.7% of citric acid, 0.04-0.09% of sodium tartrate, 15-20%of tartaric acid, 0.3-0.6% of pimelic acid, 0.3-0.5% of copper formate tetrahydrate, 35-40% of dicalcium silicate compound powder materials, 0.02-0.05% of monox compound materials and the balance dicalcium silicate. The cement-based crystal master batch material is applied to cement, has better water-proof performance and is harmless to human bodies, and the preparation method is simple in processand low in production cost and is applicable to industrial production.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a cement-based crystalline masterbatch material and a preparation method. Background technique [0002] Cement-based crystalline masterbatch materials are used as building materials, and can be widely used in fields such as airports, sports venues, subways, and building construction. CN201611186413.9 discloses a cement-based high-permeability crystalline masterbatch concrete, including high-permeability crystalline masterbatch 8- 12 parts by mass, 60-150 mesh graded quartz sand 35-50 parts by mass, redispersible rubber powder 0.5-2 parts by mass, water reducing agent 0.3-0.5 parts by mass, defoamer 0.3-0.5 parts by mass number, 0.2-0.4 mass fractions of cellulose ether, 40-60 mass fractions of cement and 80-120 mass fractions of water. But the performance is still low. Contents of the invention [0003] The object of the present invention is to provide a cement-based crystalli...
