MasterFlow 928T
Non-shrink natural-aggregate cementitious precision grout for baseplates and machinery
Product Overview
MasterFlow 928T is a high-strength, non-shrink cementitious precision grout supplied as a ready-to-use powder needing only on-site water to give predictable, shrinkage-compensated performance. It can be placed at any consistency from fluid to damp-pack, hardens free of bleeding, settlement and drying shrinkage, and contains micro-silica that enhances strength, durability and impermeability. It offers high bond strength to steel and concrete plus good fatigue and impact resistance, and complies with ASTM C1107 (Grade C) and CRD-C 621. It is part of the Master Builders Solutions range (formerly BASF Construction Chemicals), supplied in India by Space Arc Engineering, an Authorized Project Distributor. Typical uses include turbines, generators, presses, crane rails, anchor bolts and bridge bearings. Follow the technical data sheet for water content, consistency and curing.
Features & Benefits
- Adjustable consistency from fluid to damp-pack for varied applications
- Non-shrink: hardens without bleed, settlement or drying shrinkage
- Micro-silica content enhances strength, durability and impermeability
- High bond strength to steel and concrete
- Good fatigue and impact resistance for dynamic machinery
- Early strength development even at fluid consistency
Technical Highlights
| Coverage | Fills voids from about 25 mm to 100 mm; above 100 mm can be extended with 5-13 mm clean aggregate (typically 10-15 kg per 25 kg bag). Mix water for fluid grout about 4.5-5 litres per 25 kg bag. |
| Strength | At 25°C (fluid, ~4.5 L water per bag): compressive strength about 20 N/mm² at 1 day, 35 N/mm² at 3 days, 45 N/mm² at 7 days and 60 N/mm² at 28 days; flexural strength about 4.0-9.0 N/mm² from 1 to 28 days. |
| Performance | Wet density approx. 2220 kg/m³ with no apparent bleed water (ASTM C232) at recommended water; complies with ASTM C1107 Grade C and CRD-C 621. |
| Application Conditions | Keep mixed grout below 30°C in hot weather and above 10°C in cold; pre-soak substrate and maintain a hydrostatic head when pouring — refer to TDS. |
| Packaging | Supplied in 25 kg moisture-resistant bags; can be extended with clean 5-13 mm aggregate for large-volume void filling. |
Applications
- Precision grouting of gas and steam turbines and generators
- Grouting of presses, crane rails and milling machines
- Setting of anchor bolts and holding-down bolts
- Bedding of bridge bearings in infrastructure projects

Frequently Asked Questions
What is MasterFlow 928T used for?
It is a high-strength non-shrink precision grout for bedding and grouting critical equipment such as turbines, generators, presses, crane rails, milling machines, anchor bolts, precast elements and bridge bearings.
What compressive strength does MasterFlow 928T reach?
At 25°C and fluid consistency (about 4.5 litres water per 25 kg bag) it typically develops around 20 N/mm² at 1 day, 45 N/mm² at 7 days and 60 N/mm² at 28 days. Confirm against the current TDS.
Can MasterFlow 928T be extended with aggregate?
Yes. For large-volume void filling it can be bulked with clean, washed 5-13 mm aggregate, typically 10-15 kg per 25 kg bag, confirmed by site trials per the TDS.
What standards does MasterFlow 928T comply with?
It complies with ASTM C1107 (Grade C) and CRD-C 621, and shows no apparent bleed water under ASTM C232 at recommended water addition.
