Brief Introduction：
Architectural masonry and plastering additives for aerated blocks consists of
polymer and several high-efficient additives. It has good cohesive strength, water
retention and crack resistance so it makes sure of best cohesive performance
of aerated blocks.
Features：
1. Good water retention, strong cohesive strength, and high compressive strength so it makes aerated blocks with good cohesive strength, good frost-resistance, safety, non-cracks and non-crack-hollows.
2. Good workability, convenient to use in construction, speed up construction efficiency.
3. Time-saving, energy-saving, economical and practical, durable, and environmental safety.
Usage Range:
It can be used in architectural masonry mortar and plastering mortar for all kinds of coal ash and aerated blocks.
Reference Mixture Ratio:
The mixture ratio of agent to cement is 0.5%--0.7%, and here is a measurement spoon in every pack.
Usage：
1. Mixing procedure while using vertical mixers, horizontal mixers: Firstly, mix part sand, agent and water and stir them uniformly. Put cement and all sand into them. At last, stir the mixture for 3~5 minutes.
2. Mixing procedure while using drum-type mixers: Put agent, cement, and sand together, stir them for 1 minute. And then add water to the mixtures and stir for 3~5minutes.
3. Artificial mixing: the agent should be first dissolved into the water then placed into mortar.
4. The first mixing mortar, the quantity of agent should be increased 1 time.
5 The water in the mortar with the agent should be reduced by 20%.
6 The mixture ratio of agent fluctuates with different cement and sand. So the reasonable ratio should be depended on the materials at the site and trial.
