General describle:

CSA binder is a hydraulic binder not blending  with anhydrite,slag,gypsum ect mixture.Its main raw material is calcium sulphoaluminate.And it is designed to use in formulated products either as a hydraulic binder by itself or as CSA additives in combination with portland cement,silicate cement or other mineral materials as well as chemical additives.

Characteristic changed use as CSA additives:

In addition to CSA binder, it can change the properties of mixtures like:
Adjustable setting time without impact the later compressive strength.
High rheology,which has 20 mins manipulating time after mixing.
Mechanical performance,the early strength can reach 75Mpa in only 7days.

CSA binder is performed under a strict system GB/T 19001-2000 and GB/T 24001-1996 which accommodates the technical and environmental requirements of building chemical formulators.

Application:

With properties it possessed, CSA binder are applied to obtain a wide range of products:
Fast setting cement
Rapid hardening mortar
Tile adhesive
Self-leveling compound
Non-shrinking grout
Water stopping mortar
ect.

CSA binder may be used in combination with chemical additives such as:
Ploymers,either in latex form or redispersible powder form:
Defoamers,
Retarders,
Accelerators,
Plasticizers
Fibers
ect.

Reactivity with Portland cement
CSA 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, CSA cement clinker 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 CSA cement clinker. The amount of CSA cement clinker 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 CSA cement clinker /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, however it is necessary to check the behaviour of each PORTLAND cement used. 
 
The characteristic of portland cement to be considered as:
C3A content
Mineral admixture type and content
Type of calcium sulphate used
Alumina cement:
 
The characteristic comparing to Ciment Fondu :
Its properties are smiliar to Alumina cement and Ciment Fondu  except refactory.However,it has more favorable price than alumina cement and Fondu cement.
 
common properties:
raipd hardening
fast setting 
high early compressive strength
low alkali
sulphate resistance
aci-water proof 
high degree of compaction
contrast:
1.The main raw materials of csa cement is calcium sulphoaluminate while calcium aluminate consist of Fondu.
2.the ettringite in csa cement has properties of micro expansion and low shrinkage ratio which can avoid  the surface of construction from cracking.
3.the high percentage of alumina make Fondu have good refactory and stability.
 
CSA cement can use alone as a primary agent(lithium accelerate gent),or mix with other OPC,silicate cement, calcium sulphate and other additive agent ect.

FAQ: 

Q1:Are you a factory? 
 A:Yes,we are a factory,but not just a factory,as we have sales team,our own offices,
professioners,masters and doctors,and they all can help the buyers and cooperative
partners to decide which products are the best choices for them,and all your require-
ments and inquires will be replyed in time.
