Abstract
The invention discloses a kind of concrete water-retaining agent, which is characterized in that is made of the raw material of following parts by weight：20-50 parts of hydroxypropyl methyl cellulose, 15-25 parts of bentonite, 5-10 parts of diatomite, 3-6 parts of starch ether, 5-10 parts of zeolite, 3-8 parts of stearic acid, 5-10 parts of polyvinyl alcohol, 5-12 parts of calcium sulphoaluminate, 1-5 parts of neopelex.The present invention provides a kind of concrete water-retaining agent, and there is higher water retention, performance to stablize, and can improve the intensity of concrete, cracking resistance and concrete durability.
Description
Technical field
The present invention relates to technical field of concrete additives more particularly to a kind of concrete water-retaining agent.
Background technology
Cement needs enough water in hardening process and reacts, and just can guarantee the intensity of cement.It is general to require just
Ready-made concrete need to sprinkle water maintenance 7 days or more.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 soil water conservation is that suitable cellulose is added.Fiber is known as certain water retention, but effect is bad.Currently on the market
Have the curing agent for playing water retention, such as organosilicon curing agent, this kind of curing agent mechanism of action generally concrete formation 4~
One layer of curing agent is being sprayed above again after 8 hours, so that concrete surface is formed one layer of hydrophobic film, to play maintenance action.This
Sample curing agent need to individually construct, complex procedures.In addition, existing water-retaining agent compounding still has, stability is poor, and there are lag to secrete
Phenomena such as water, isolation.
Invention content
The object of the present invention is to provide a kind of concrete water-retaining agent, have higher water retention, performance is stablized, and energy
Enough improve the intensity of concrete, the durability of cracking resistance and concrete.
