Abstract
The invention discloses a kind of concrete water-loss reducer, it is formulated by following component according to following weight ratio：10 18 parts of bentonite, 28 parts of polypropylene fibre, 30 40 parts of cellulose ether, 25 parts of starch ether, 8 12 parts of zeolite, 5 10 parts of stearic acid, 48 parts of polyvinyl alcohol, 26 parts of neopelex.The water-loss reducer of the invention is added in concrete, can effectively reduce the cost of concrete, and concrete construction is good, and adhesive strength is high, high comprehensive performance, is worthy to be popularized.
Description
Technical field
The invention belongs to technical field of concrete additives, and in particular to a kind of concrete water-loss reducer.
Background technology
Cement needs enough water in hardening process and reacted, and just can guarantee that the intensity of cement.It is general to require firm
Ready-made concrete, which need to sprinkle water, to be conserved more than 7 days.But in many Practical Projects, often do not accomplish that watering conserves 7 days, and cement
The ratio of the moisture evaporation on surface is very fast, if do not retained the moisture in concrete, will certainly influence the intensity of cement.Traditional coagulation
The method of native water conservation is to add appropriate cellulose.Fiber is known as certain water retention, but effect is bad.In the market
There is the sealing compound for playing water retention, such as organosilicon sealing compound, this kind of sealing compound mechanism of action is generally in concrete formation 4-8
One layer of sealing compound is being sprayed above again after hour, concrete surface is formed one layer of hydrophobic film, so as to play maintenance action.So
Sealing compound need to individually construct, complex procedures.In addition, to still have stability poor for existing water-loss reducer compounding, exist hysteresis bleeding,
Phenomena such as isolation.
The content of the invention
The technical problems to be solved by the invention are to provide concrete water-loss reducer, and it has a higher water retention, and performance is steady
It is fixed, bonding force is strong, it is possible to increase the durability of the intensity of concrete, cracking resistance and concrete.
The technical scheme that the present invention solves technical problem is as follows：
A kind of concrete water-loss reducer, is formulated by following component according to following weight ratio：Bentonite 10-18 parts, poly- third
Alkene fiber 2-8 parts, cellulose ether 30-40 parts, starch ether 2-5 parts, zeolite 8-12 parts, stearic acid 5-10 parts, polyvinyl alcohol 4-8
Part, neopelex 2-6 parts.
One of preferably, described concrete water-loss reducer, it is formulated by following component according to following weight ratio：
14 parts of bentonite, 5 parts of polypropylene fibre, 35 parts of cellulose ether, 3.5 parts of starch ether, 10 parts of zeolite, 7.5 parts of stearic acid, polyethylene
6 parts of alcohol, 4 parts of neopelex.
One of preferably, described bentonite is sodium bentonite.
One of preferably, described cellulose ether is the hydroxypropyl methyl cellulose that viscosity is more than 300,000 mpa.s
Ether.
One of preferably, described starch ether is hydroxypropyl starch ether of the degree of etherification falling in 20-25%.
It is an advantage of the invention that：The selection of concrete waterproofer raw material and dosage collocation of the present invention are reasonable, by adopting
With the appropriate starch ether of highly viscous cellulose ether collocation, it is ensured that can also control mortar while the water-retaining property of thermal insulation mortar
Appropriate viscosity, compounding, polymerisation along with other raw materials, preferably improve mortar encapsulation, water-retaining property, carry
STOL slurry viscosity.The water-loss reducer of the invention is added in concrete, can effectively reduce the cost of concrete, and coagulation soil application
Work is good, and adhesive strength is high, high comprehensive performance, is worthy to be popularized.
