Reactivity with Portland cement

HCSA BINDER may be used in combination with other mineral products, for example

PORTLAND cement, calcium sulphates and fillers, or with organics such as polymers in latex

form or in redispersible form.

Depending on the type of mixes and technology employed, HCSA BINDER can be used to obtain

and control various properties.

The behaviour of PORTLAND cement is vary variable. In general, acceleration of set increases

progressly with the addition of HCSA BINDER. The amount of HCSA BINDER needed to obtain

a specific setting time varies considerably depending on the origin of the PORTLAND cement and

performance can be modified with the use of additives.

The strength development of HCSA BINDER/PORTLAND cement and/or Calcium Sulphates

depend on the nature of the PORTLAND cement and/or Calcium Sulphates used. In general these

mixes will develop mechanical strength at a very early stage (several hours). With some type of

PORTLAND cements and in formulated products containing additives which control the setting

and hydration, the long term properties is similar to those of the original PORTLAND cement,
