What Is Mortar?

Mortar is a mixture of cement (or gypsum), sand, fillers, and functional additives used for bonding, leveling, repairing, and finishing construction surfaces.

Modern dry mix mortar relies heavily on specialty chemical additives to improve:

Workability
Water retention
Bonding strength
Flexibility
Crack resistance
Setting time control
Durability

Without proper additives, mortar performance cannot meet current construction standards.

Core Mortar Additives by Function

Cellulose Ether (HPMC / HEMC / HEC)

Cellulose ether is the most essential additive in dry mix mortar.

Excellent water retention
Improved workability
Extended open time
Enhanced anti-sag performance
Better cement hydration

Polycarboxylate Superplasticizer (PCE)

PCE improves dispersion and flow.

Reduced water demand
Improved flowability
Higher early strength
Increased density

Especially suitable for:

Redispersible Polymer Powder(RDP)

Increased bonding strength
Improved flexibility
Enhanced impact resistance
Better adhesion to difficult substrates
Improved water resistance

Michem’s RDP products are ideal for:

Polypropylene Fiber

Provides reinforcement:

Crack resistance
Reduced shrinkage
Improved tensile strength
Better impact resistance

Suitable for:

Hydroxypropyl Starch Ether

Improves construction performance:

Enhanced anti-sag property
Improved thixotropy
Better troweling performance
Optimized consistency

Calcium Formate

Acts as early strength accelerator:

Faster setting time
Improved early strength
Ideal for cold weather applications

Silicone Hydrophobic Powder

Improves mortar durability:

Enhanced water repellency
Reduced water absorption
Improved freeze-thaw resistance

General FAQs

Frequently Asked Questions Questions

What additives are essential in dry mix mortar?

Cellulose ether (HPMC) is essential, followed by RDP, superplasticizer, fiber, and performance modifiers depending on application type.

Why is RDP important in polymer modified mortar?

RDP improves adhesion, flexibility, impact resistance, and durability.

Can Michem provide technical formulation support?

Yes, we provide application-based formulation optimization.

Do you supply additives for all mortar types?

Yes, we cover bonding, plastering, repair, waterproof, self-leveling, and insulation mortars.

How to dissolve Hydroxyethyl Cellulose in water?

Proper dissolution is critical for HEC performance:

Dispersion: Add HEC slowly to vortex of agitated water (not vice versa)
Particle Size: Use fine mesh grades (80-100 mesh) for faster dissolution
Temperature: Start with cold water (15-25°C); heat after hydration
pH Adjustment: Add acids/bases only after full hydration
Time: Allow 20-30 minutes for complete hydration

Pro Tip: Pre-dispersing in glycerol or alcohol prevents lumping in high-shear systems.

What is Hydroxyethyl Cellulose price per kg?

Hydroxyethyl Cellulose pricing depends on:

Viscosity grade: Higher viscosity = higher price
Purity level: Industrial vs. cosmetic vs. pharmaceutical grade
Order volume: Bulk orders (FCL) receive significant discounts
Customization: Special particle sizes or packaging

Price Range (2024):

Industrial Grade: $3.50-5.50/kg
Cosmetic Grade: $5.50-8.00/kg
Pharmaceutical Grade: $8.00-15.00/kg
