Blockadd C
Admixture for cement/concrete blocks
Blockadd C is a mortar admixture that improves the workability, strength, cohesion and improves resistance to freeze/thaw cycles, by entraining a controlled quantity of air to the mortar mix.
- Improving mortar plasticity.
- Reducing permeability.
- Chloride free, safe for embedded steel.
- Compatible with most types of Portland cement.
- Improves frost resistance.
- Can be used to replace lime.
- Improves bond strength.
- Strength increase through water reduction.
- Cement saving through strength maintaining with less cement.
Blockadd C is used to improve workability, strength, surface finish and freeze/thaw cycle resistance properties for concrete blocks, pipes, roofing tiles, concrete bricks and pavers.
Blockadd C is available in 5, 20 and 200 litre containers.
Blockadd C has a shelf life of 12 months from date of manufacture if stored at temperatures below 50°C.
Blockadd C is supplied in liquid form and should be added directly to the mortar mix at the rate of 100 - 300 ml per 50 kg of cement, depending upon sand used and consistency required.
Blockadd C complies with BS 4887: Mortar Plasticisers.
