Viaduct Blackbox for Block Jointing Mortar
Viaduct Blackbox for Block Jointing Mortar is a pre-engineered formulation system developed to help manufacturers produce high-strength, consistent, and easy-to-apply mortar for AAC blocks, CLC blocks, and concrete blocks. Built on a controlled polymer-based formulation, it replaces conventional site-mixed mortar with a modern, thin-joint solution that delivers superior bonding and uniform performance.
Just open the Blackbox, mix it with the prescribed raw materials in the recommended ratio, and the complete block jointing mortar formulation is ready for production. No formulation trials. No dependency on site workmanship. No R&D investment.
This engineered system ensures strong inter-block adhesion, reduced material consumption, improved workability, and consistent batch quality—allowing manufacturers to offer a reliable block jointing mortar suitable for fast, accurate masonry construction. Easy to manufacture, simple to control, and trusted in performance, Viaduct Blackbox is the smarter way to produce block jointing mortar with confidence.

How to Use Viaduct Blackbox in Manufacturing
Prepare Mixing Equipment
Ensure mixers are clean, dry, and free from previous batch residues.
Measure Raw Materials
Weigh cement, graded sand, fillers, and additives as per the formulation guide.
Open the Blackbox System
Check that the polymer system is moisture-free and ready for blending.
Add Blackbox to Dry Mix
Introduce the Blackbox polymer into the mixer along with measured raw materials.
Blend Uniformly
Mix for the prescribed duration to achieve a homogeneous mortar powder.
QC Verification
Check bulk density, flow, and basic bonding parameters as per QC guidelines.
Packing & Storage
Pack the finished mortar into bags, seal properly, and store in dry conditions.
