Concrete expansive mortar additives applied to building engineering
Concrete expansive mortar additives is a kind of low-alkali, low-dosage but high performance
products.And it belongs to calcium sulphoaluminate concrete expansion agent,the performance
is very stable.Doped 8%-10% of expansive agent in the concrete admixture cement can
compensate the shrinkage of concrete,improve the crack and seepage resistance control
function of concrete, and make it become concrete with excellent waterproof impermeability.
The technical performance of concrete expansive mortar additives as follows:
Test items | Test results |
Appearance | Powder |
Dosage | 8-10% |
Impermeability grade | >P20 |
Expanders can improve adhesion | 20%-30% |
8% ash concrete expansion | 7days to reach 0.08% |
Concrete expansion | Non-toxic, odorless, non-flammable, non-chlorine salt,no corrosive effect on steel. |
Method of use:
1.When using this product, the same amount of gelled material of concrete replaced, recommended dosage is 8-10%, and the post-pouring strengthening band concrete afterpouring, need appropriate
parameters.
2.This product configuration of the concrete can be used from structure waterproof technology, making building and waterproof in one, external waterproof can be canceled. Make the structure more
simple.
3.Concrete with this product can use the long seamless design and construction technology of
reinforced concrete. Reduce the construction process, make construction simpler, greatly shorten the time limit for a project. Can also be used to deal with the common concrete cracks.
1.Belongs to calcium sulphoaluminate concrete expansion agent ,the performance is very stable.
2.Doped 8%-10% of expansive agent in the concrete admixture cement,can compensate the
shrinkage of concrete ,improve the crack and seepage resistance control function of concrete, and make it become concrete with excellent waterproof impermeability.
3.As long as the concrete and component engineering have the requirements of impermeable and
anti-cracking,this product can be mixed to compensation shrinkage concrete. Such as: building
basements, underground structures, pool, swimming pool, sewage treatment ponds, water tower and storage tank, subway, tunnel, water conservancy and hydropower, Marine engineering waterproof
structure, such as the stadium, radiation protection of concrete structures.
4.The product can also be used to formulate concrete filled swelling and swelling filled with mortar,
such as: beam column joints, the joints filled with poured concrete, mechanical equipment and
perfusion secondary reinforcement, etc.
