What is the difference between ALC mortar and normal cement mortar?

ALC mortar is specially designed for lightweight porous blocks. It requires higher water retention, better adhesion and improved flexibility compared with traditional mortar.

Why is HPMC used in AAC block adhesive mortar?

HPMC controls water retention and rheology, helping maintain moisture for cement hydration and improving workability.

What is the recommended RDP dosage for ALC mortar?

Typical dosage is around 1–3%, depending on adhesion and flexibility requirements.

Is PCE Powder necessary in AAC adhesive mortar?

Basic formulas may not require PCE, but premium systems can benefit from reduced water demand and improved strength performance.

Why does ALC block mortar crack?

Common causes include insufficient water retention, poor adhesion, excessive shrinkage or unsuitable formula balance.

How can manufacturers improve AAC adhesive mortar performance?

By optimizing raw materials, selecting suitable HPMC/RDP grades and adjusting the formulation according to local materials and climate conditions.
