Silica Sol for Cement Grade Comparison
| Model | Particle Size | SiO₂ Content | Na₂O Content | pH | Shelf Life |
|---|---|---|---|---|---|
| HC4010 | 10–15 nm | 40±1% | ≤0.4% | 9.5–10.5 | ≥12 months |
| HC4020 | 20–30 nm | 40±1% | ≤0.4% | 9.5–10.5 | ≥12 months |
| HC5020 | 20–30 nm | 50±1% | ≤0.4% | 9.5–10.5 | ≥12 months |
The HC grades are representative candidates for cement-paste, mortar and cementitious-product trials. They are not universal admixtures; dosage and suitability must be established through the actual mix design.
Balance Silica Solids, Particle Size and Mix Water
Adding silica sol changes both nanosilica input and liquid balance. Grade selection should therefore be tied to cement chemistry, water-to-binder ratio, admixtures, mixing energy and curing conditions.
HC4010 Fine-Particle Candidate
Provides 40±1% SiO₂ with the finer listed particle range for controlled cement-paste and mortar comparison trials.
HC4020 Larger-Particle Candidate
Maintains 40±1% SiO₂ while allowing particle-size effects to be compared at the same published solids level.
HC5020 Higher-Solids Candidate
Provides a higher silica concentration where limiting liquid introduced by the dispersion is a formulation objective.
Test the Complete Binder System
Confirm dispersion, flow, air, setting, shrinkage, strength and durability with all cementitious materials and admixtures present.
What to Provide Before a Cement Trial
- Cement type: identify clinker type, strength class, alkali level and any supplementary cementitious materials.
- Mix proportions: provide binder content, aggregate grading, fillers, water-to-binder ratio and target batch size.
- Admixture package: list superplasticizer, accelerator, retarder, air-control agent, fibers and other additives.
- Addition plan: state the silica-sol dosage basis, mixing sequence, mixing time and water adjustment method.
- Performance targets: define flow or slump, setting, early and later strength, shrinkage, abrasion and permeability.
- Curing conditions: provide temperature, humidity, curing duration, demolding time and intended service exposure.

Packaging Options
Available polyethylene packaging sizes are 25 kg, 250 kg and 1000 kg.
Storage Temperature
Store at 0–40°C and prevent freezing. Temperatures below 0°C can cause irreversible gelation.
Direct Sunlight
Avoid prolonged direct sunlight during storage and transportation.
Container Closure
Keep containers closed to limit evaporation and precipitation of solid silica particles.
Silica Sol for Cement FAQ
Which silica-sol grades can be evaluated in cement systems?
HC4010, HC4020 and HC5020 are representative high-solids candidates for cement-paste, mortar and cementitious-product trials.
What is the difference between HC4010 and HC4020?
Both contain 40±1% SiO₂. HC4010 has a listed particle size of 10–15 nm, while HC4020 is 20–30 nm.
Why must mix water be adjusted during testing?
Silica sol is an aqueous dispersion. Its water contribution should be included when comparing water-to-binder ratio and workability with the control mix.
Can silica sol be used with a superplasticizer?
Compatibility depends on cement chemistry and admixture type. Test flow, retention, air, setting and strength using the actual superplasticizer.
How should silica sol for cement use be stored?
Store it at 0–40°C, prevent freezing and prolonged sunlight, and keep the package closed when not in use.

Applications of Silica Sol for Cement
High-solids silica sol can be evaluated in compatible cementitious systems. Grade and dosage qualification must use the actual cement, supplementary materials, admixtures, mixing method and curing conditions.
Cement Paste Development
Controlled trials can compare hydration, flow, setting and strength at defined silica-sol dosages and water balance.
Dry-Mix Mortar
Silica sol may be evaluated in liquid-added mortar systems after compatibility, workability and storage logistics are confirmed.
Repair Mortars
Candidate grades can be tested for flow, bond, setting, shrinkage and mechanical performance in repair formulations.
Cementitious Coatings
Suitable grades may be assessed in mineral coatings requiring controlled aqueous nanosilica input.
Precast Cement Products
Trials can evaluate mixing, molding, demolding, curing, surface quality and early handling strength.
High-Performance Cement Systems
Selected grades can be screened with supplementary materials and superplasticizers under defined performance criteria.
