Dry-mixed mortar types and characteristics of
Dry-mixed mortar, also known as pre-mixed mortar, which is the
ingredient in the plant by the accuracy and uniformity of the
mortar made from a mixture of semi-finished products to the
construction site, just add water mix can be used.
1, the product categories
1. Kai leveling floor mortar: The Japanese typically self-leveling
floor cement mortar. From cement, sand, fly ash, expansion agent,
water reducing agent and protecting agent such as the preparation
made. Self-leveling mortar Just add water according to regulations
on-site mixing, down on the ground, automatic leveling, curing can
be obtained after the smooth flat surface.
2. Plasticized mortar: The mortar is called admixture plasticizer
plasticized mortar. Plasticizing agent is a surface active
substance, can significantly reduce the surface tension of the
solution. In the mortar mixing water generated during the closure
of a large number of tiny bubbles, which can improve the
workability of mortar mixing materials to improve the performance
of mortar and anti-permeability properties of antifreeze.
3. Decorative mortar: Color mortar commonly used in the plaster in
the wall out of brick masonry when the imitation of the appearance
or texture finishes with an oriental style, but also has a sealed
water-resistant properties, suitable for outdoor decoration.
4. Anti-, radiation mortar: In order to protect staff from , -ray
damage, the development of anti-, radiation from the mortar cement,
barite powder, barite basestocks such as sand and yellow sand.
5. Anti-neutron radiation mortar: In order to protect staff against
neutron radiation damage, anti-neutron radiation from the mortar
cement, lime, barite powder, calcium powder such as the preparation
of boric acid made hard.
6. Insulation masonry mortar: Department of the cement, fly ash,
lime, aggregate, and composite admixture of light through the
ingredients, measuring, are mixed, packaged as a dry-mixed mortar.
The composite additive can stimulate the activity of fly ash to
improve mortar workability, water retention, and bond strength, and
reduce the water absorption of lightweight aggregate, lightweight
aggregate and the paste to improve between the bullock knot
strength, frost resistance and strength.
7. Low-shrinkage cracking waterproof mortar: For the current
application of new wall materials, cracks issues, from improving
mortar bullock knot strength and reduce shrinkage point of view,
the development of low-shrinkage cracking waterproof mortar is
cement, the sand , fly ash, slag powder and the preparation of
compound additives made.
8. Concrete floor wear mortar: use of affinity and concrete have
excellent high-strength grades of special cement for the cementing
material. With Mohs hardness of 9 and the particle surface
irregular-shaped mineral material aggregate, Combined with other
supporting materials, through the mechanization and evenly mixed.
9. Waterproof mortar: fine quartz sand thin slurry of
cement, relying on closed soaked up water by capillary effect;
ultra-waterproof mortar with coagulation, by Cypriot expansion and
the role of various real-time waterproof; semi-flexible
two-component mortar, can be anti-0.2MPa water pressure and prevent
the emergence of crack width to 0.8mm.
10. Polymer modified mortar: is mixed in cement mortar by adding
water and dispersed in the polymer material. Can be used for
floors, walkways, stairs and other indoor and outdoor masonry and
concrete spalling and other damage at the thin-layer repair.
11. Anchorage mortar: It is a kind of mixing with water in the
field is to be pouring slurries. Used mainly for masonry anchor
bolts in masonry or concrete, machinery and equipment foundation,
fence rails, columns, poles and partitions and so on, is
characterized by not contain corrosive to metal components;
quick-setting, anti-vibration, good ; not best placed to compensate
for shrinkage or contraction of concrete.
12. Tile adhesive mortar: These are mostly mortar cement, sand and
organic matter in the ready-mix mixture can be used for all kinds
of indoor and outdoor wall and floor tiles (tile, stone) the
structure and pointing and so on.
