1.THE CONTENT OF DRY MORTAR PRODUCTS:
(1) Aggregates: stones, sand etc
(2) Adhesive: Cement or gypsum.
(3) Additives: Cellulose ether, redispersible polymer powder, water reducer(PCE),PP firber etc.
2.MAIN ADDITIVES / CHEMICALS IN DRY MIX MORTAR AND PERFORMANCE.
(1) Cellulose ether: HPMC-hydroxypropyl methyl cellulose ; HEMC-Hydroxyethyl methyl cellulose
Cellulose ether-HPMC or HEMC is the most important chemicals in dry mix mortar formulation.
Good water retention is the important for the adhesives(cement or gypsum) hydration.
Meanwhile, make sure other additives work. At the same time, cellulose ether also have other
functions in the formuliation:
-Improve the workability
-slip / sag - resistence
-adjust open time
-water demand
-Increase bonding strength and compressive strength
Cellulose ether(HPMC,HEMC) is required to be added in all types of dry mix mortar
(2) Redispersible polymer powder (RPP)
Redispersible polymer powder(RPP / RDP) is one of the important additives in dry mix mortar.
Choose different type of RDP could increase the bonding strength or dry mortar and increase the
flexibility. Meanwhile, it can also make contribution on the workability and waterproofing.
It is widely used in tile adhesive, wall plaster or EIFS mortar etc.
(3) Starch ether
Normally, starch ether is used together with cellulose ether. It could improve the water retention and
workability. In the same time, it could be helpful in extending the open time and reach better
consistency.
3.DIFFERENT KINDS OF DRY MIX MORTAR
Wall putty / plaster
Tile adhesive
Masonry mortar/blocks laying mortar
Joint filler
EIFS mortar
Self-leveling mortar
etc.
